Transcript of Omeprazole Drug Profile
INTRODUCTION
INTRODUCTION
Drug Omeprazole
Omeprazole is a proton pump inhibitor used in the treatment of dyspepsia, peptic ulcer disease
(PUD), gastroesophageal reflux disease (GORD/GERD), laryngopharyngeal reflux (LPR), and
Zollinger-Ellison syndrome. It was first marketed in the US in 1989 by AstraZeneca under the brand
names Losec and Prilosec, and is now also available from generic manufacturers under various brand
names. AstraZeneca markets omeprazole as Losec, Antra, Gastroloc, Mopral, Omepral, and Prilosec.
Omeprazole is marketed as Zegerid by Santarus, Prilosec OTC by Procter & Gamble and Zegerid OTC
by Schering-Plough. In India it is available as OMEZ (FGP). Omeprazole is one of the most widely
prescribed drugs internationally and is available over the counter in some countries.
Pharmacology
Omeprazole is a racemate. It contains a tricoordinated sulfur atom in a pyramidal structure and
therefore can exist in equal amounts of both the S and R enantiomers. In the acidic conditions of the
stomach, both are converted to achiral products, which react with a cysteine group in H + /K
+ ATPase ,
thereby inhibiting the ability of the parietal cells to produce gastric acid.
Name change
In 1990, at the request of the U.S. Food and Drug Administration (FDA), the brand name Losec
was changed to Prilosec to avoid confusion with the diuretic Lasix (furosemide). Unfortunately, the new
name has led to confusion between omeprazole (Prilosec) and fluoxetine (Prozac), an antidepressant.
Clinical use
Use in Helicobacter pylori eradication
Omeprazole is combined with the antibiotics clarithromycin and amoxicillin (or metronidazole
in penicillin-hypersensitive patients) in the 7-14 day eradication triple therapy for Helicobacter pylori.
Infection by H. pylori is the causative factor in the majority of peptic and duodenal ulcers.
Side effects
Some of the most frequent side effects of omeprazole (experienced by over 1% of those
taking the drug) are headache, diarrhea, abdominal pain, nausea, dizziness, trouble awakening and sleep
deprivation, although in clinical trials the incidence of these effects with omeprazole was mostly
comparable to that found with placebo.
Proton pump inhibitors may be associated with a greater risk of hip fractures, and clostridium
difficile-associated diarrhea. ] Patients are frequently administered the drugs in intensive care as a
protective measure against ulcers, but this use is also associated with a 30% increase in occurrence of
pneumonia.
Other side effects may include bone rebuild interference and B12 vitamin reduction.
Interactions
Omeprazole is a competitive inhibitor of the enzymes CYP2C19 and CYP2C9, and may
therefore interact with drugs that depend on them for metabolism, such as diazepam, escitalopram, and
warfarin; the concentrations of these drugs may increase if they are used concomitantly with
omeprazole.Clopidogrel (Plavix) is an inactive prodrug that partially depends on CYP2C19 for
conversion to its active form; inhibition of CYP2C19 blocks the activation of clopidogrel, thus reducing
its effects and potentially increasing the risk of stroke or heart attack in people taking clopidogrel to
prevent these events.Omeprazole is also a competitive inhibitor of p-glycoprotein, as are other PPIs.
Drugs that depend on stomach pH for absorption may interact with omeprazole; drugs that depend
on an acidic environment (such as ketoconazole or atazanavir) will be poorly absorbed, whereas drugs
that are broken down in acidic environments (such as erythromycin) will be absorbed to a greater extent
than normal.
St. John's wort (Hypericum perforatum) and Gingko biloba significantly reduce plasma
concentrations of omeprazole through induction of CYP3A4 and CYP2C19.
Absorption and distribution
The absorption of omeprazole takes place in the small intestine and is usually completed within 3– 6
hours. The systemic bioavailability of omeprazole after repeated dose is about 60%. Omeprazole
bioavailability is significantly impaired by the presence of food and, therefore, patients should be advised
to take omeprazole before eating. The capsule should be taken immediately before a meal. The MUPS
tablet may be taken with or without food. The powder for oral suspension should be taken on an empty
stomach at least 1 hour before a meal. Plasma protein binding is about 95%.
Metabolism and excretion
Omeprazole is completely metabolized by the cytochrome P450 system, mainly in the liver.
Identified metabolites are the sulfone, the sulfide and hydroxy-omeprazole, which exert no significant
effect on the acid secretion. About 80% of an orally given dose is excreted as metabolites in the urine and
the remainder is found in the feces, primarily originating from bile secretion.
FORMULATIONS AND DOSAGE FORMS
Omeprazole is available as tablets and capsules (containing omeprazole or omeprazole
magnesium) in strengths of 10 mg, 20 mg, 40 mg, and in some markets 80 mg; and as a powder
(omeprazole sodium) for intravenous injection. Most oral omeprazole preparations are enteric-coated,
due to the rapid degradation of the drug in the acidic conditions of the stomach. This is most commonly
achieved by formulating enteric-coated granules within capsules, enteric-coated tablets, and the multiple-
unit pellet system (MUPS).
It is also available for use in injectable form (I.V.) in Europe, but not in the U.S. The injection
pack is a combination pack consisting of a vial and a separate ampule of reconstituting solution.
Multiple unit pellet system
Omeprazole tablets manufactured by AstraZeneca (notably Losec/Prilosec) are formulated as a
"multiple unit pellet system" (MUPS). Essentially, the tablet consists of extremely small enteric-coated
granules (pellets) of the omeprazole formulation inside an outer shell. When the tablet is immersed in an
aqueous solution, as happens when the tablet reaches the stomach, water enters the tablet by osmosis.
The contents swell from water absorption causing the shell to burst, releasing the enteric-coated
granules. For most patients, the multiple-unit pellet system is of no advantage over conventional enteric-
coated preparations. Patients for which the formulation is of benefit include those requiring nasogastric
tube feeding and those with difficulty swallowing (dysphagia) because the tablets can be mixed with
water ahead of time, releasing the granules into a slurry form, which is easier to pass down the feeding
tube or to swallow than the pill. The granules are manufactured in a fluid air bed system. Sugar spheres
in suspension are sequentially sprayed with aqueous suspensions of omeprazole, a protective layer, an
enteric coating and an outer layer to reduce granule aggregation.
Marketing & pharmaceutical marketing
Pharmaceutical marketing, sometimes called medico-marketing or pharma marketing in some
countries, is the business of advertising or otherwise promoting the sale of pharmaceuticals or drugs.
There is some evidence that marketing practices can negatively affect both patients and the health care
profession. Many countries have measures in place to limit advertising by pharmaceutical companies.
Pharmaceutical company spending on marketing far exceeds that spent on research. In Canada, $1.7
billion was spent in 2004 to market drugs to physicians; in the United States, $21 billion was spent in
2002. In 2005 money spent on pharmaceutical marketing in the US was estimated at $29.9 billion with
one estimate as high as $57 billion. When the US numbers are broken down, 56% was free samples, 25%
was detailing of physicians, 12.5% was direct to user advertising, 4% on hospital detailing, and 2% on
journal ads.
The marketing of medication has a long history. The sale of miracle cures, many with little real
potency, has always been common. Marketing of legitimate non-prescription medications, such as pain
relievers or allergy medicine, has also long been practiced, although, until recently, mass marketing of
prescription medications has been rare. It was long believed that since doctors made the selection of
drugs, mass marketing was a waste of resources; specific ads targeting the medical profession were
thought to be cheaper and just as effective. This would involve ads in professional journals and visits by
sales staff to doctor’s offices and hospitals. An important part of these efforts was marketing to medical
students
To health care providers
Marketing to health care providers takes four main forms: gifting, detailing, drug samples, and
sponsoring continuing medical education (CME).Of the 237,000 medical sites representing 680,000
physicians surveyed in SK&A's 2010 Physician Access survey, half said they prefer or require an
appointment to see a rep (up from 38.5% preferring or requiring an appointment in 2008), while 23%
won't see reps at all, according to the survey data. Practices owned by hospitals or health systems are
tougher to get into than private practices, since appointments have to go through headquarters, the survey
found. 13.3% of offices with just one or two doctors won't see reps, compared with a no-see rate of 42%
at offices with 10 or more docs The most accessible physicians for promotional purposes are
allergists/immunologists – only 4.2% won't see reps at all – followed by orthopedic specialists (5.1%)
and diabetes specialists (7.6%). Diagnostic radiologists are the most rigid about allowing details – 92.1%
won't see reps – followed by pathologists and neuroradiologists, at 92.1% and 91.8%, respectively.
Edetailing is widely used to reach "no see physicians"; approximately 23% of primary care physicians
and 28% of specialists prefer computer-based edetailing, according to survey findings reported in the
April 25, 2011, edition of American Medical News (AMNews), published by the American Medical
Association (AMA).
New pharma code & guidelines
The Pharmaceutical Research and Manufacturers of America (PhRMA) released updates to its voluntary
Code on Interactions with Healthcare Professionals on July 10. The new guidelines take effect January
2009."
In addition to prohibiting small gifts and reminder items such as pens, notepads, staplers, clipboards, pill
boxes, etc., the revised Code:
1. Prohibits company sales representatives from providing restaurant meals to healthcare
professionals, but allows them to provide occasional meals in healthcare professionals’ offices in
conjunction with informational presentations"
2. Includes new provisions requiring companies to ensure their representatives are sufficiently
trained about applicable laws, regulations, and industry codes of practice and ethics.
3. Provides that each company will state its intentions to abide by the Code and that company CEOs
and compliance officers will certify each year that they have processes in place to comply
4. Includes more detailed standards regarding the independence of continuing medical education.
5. Provides additional guidance and restrictions for speaking and consulting arrangements with
healthcare professionals.
However, the Good Works Health government-approved platform offers physicians and other health care
professionals the opportunity to direct donations to charities of their choice in exchange for participation
in pharmaceutical promotional/educational programs.
Free samples
Free samples have been shown to affect physician prescribing behaviour. Physicians with access to free
samples are more likely to prescribe brand name medication over equivalent generic medications. Other
studies found that free samples decreased the likelihood that physicians would follow standard of care
practices.
Receiving pharmaceutical samples does not reduce prescription costs. Even after receiving samples,
sample recipients remain disproportionately burdened by prescription costs.
It is argued that a benefit to free samples is the “try it before you buy it” approach. Free Samples give
immediate access to the medication and the patient can begin treatment right away. Also, it saves time
from going to a pharmacy to get it filled before treatment begins. Since not all medications work for
everyone, and many do not work the same way for each person, free samples allow patients to find which
dose and brand of medication works best before having to spend money on a filled prescription at a
pharmacy.
Sale and techniques of sales
To become a successful sales representative you need to have a solid understanding of selling concepts. These concepts give you the foundation to understand why customers act the way they do and provide a guide as to how to use your selling skills to overcome obstacles and increase sales.
Successful Selling Steps
If we consider the steps most successful sales representatives go through to increase their effectiveness on sales calls, we will see there are three general areas for consideration:
1. Business Planning2. The Sales Call (pre-call, sales call, post-call)3. Follow-Up
Business planning is a critical step in ensuring your selling skills are most effective. Sales representatives in the healthcare industry manage their territories as if they were running their own business. To be successful in your sales territory you need to fully understand it before you attempt to call on customers. This includes knowing which customers drive your business, what their “buying” style is so you can match your selling style to it, managing an investment budget, managing your daily and weekly schedule, and working with your team to implement the territory business plans. You can view the business planning process as creating a blueprint for success. Most healthcare companies will give you a territory, a list of target customers, the sales tools needed to influence your target customers and a budget. It is up to you and your territory team to come up with a plan that will most effectively make use of these resources to increase sales.
Following the business planning process, there are three main steps to consider to improve your sales call effectiveness:
1. Pre-call planning (before you meet the customer)
2. The sales call (face to face with the customer)
3. Post-call analysis and follow-up (after your sales call)
Pre-call planning done prior to meeting your customer involves several steps such as reviewing past customer call notes, setting call objectives and preparing sales tools to be most effective in the short time with your customer. This will be covered in more detail shortly.
During the actual sales call itself, there are several steps to be aware of: opening, presenting features and benefits, probing, objection handling, etc. Making an effective sales call involves excellent skills within each of these areas and we will cover them more in-depth in the coming chapters.
After leaving each and every sales call, post-call analysis needs to be completed, and any follow-up required accurately recorded and completed. These notes which you make post-call are what you will be reviewing prior to your next appointment with your customers. Without having these notes, your effectiveness on the next call will not be as high.
One major goal of a healthcare sales representative is to be seen as a valued consultant by customers. Once you are viewed by your target customers as an excellent and credible resource (and not just another sales representative) you will have increased access and time with them – and increased face-to-face selling time is a key ingredient for success in healthcare sales. Ensuring timely follow-up to customer requests in a professional manner will go a long way in ensuring you become that value added consultant in their practices.
The Sales Cycle
A sales cycle is the stages that a typical customer goes through before agreeing to purchase or use your product. Although the ultimate goal is a sale, there are several stages which you must take the customer through before you can ask for the business.
In the first stage, called Introduction and Awareness, the customer is not yet aware that you or your products exist. They may not even know about any problems they are currently facing because they have not taken the time to consider them. Your goal with a customer at this stage is to introduce your products and services and try to identify any problem areas which your product can solve for them, their patients or the healthcare system. Moving a customer through this stage is sometimes not easy and requires certain sales techniques. Techniques used to move a customer from this stage to the next one are rapport building, probing, objection handling, and gaining feedback. Throughout this book you will learn how to improve each of these skills to be successful in a healthcare sales role.
The second stage is Identification. At this stage you need to convince the customer that a problem does indeed exist. This is sometimes the hardest stage to get through as many customers will tell you that they are happy with their current product. To move the customer through this stage, sales skills such as presenting features and benefits, probing, gaining feedback, and the ability to handle objections will be needed.
In the third stage, the Knowledge stage, you must educate the customer on what your company and products offer using the features and benefits of your products and or services. Without the proper knowledge of what you and your company can offer (to the customer, the patient or the healthcare system), the customer will not be able to evaluate his options properly. Excellent use of features and benefits, probing, and objection handling will help you to move the customer through this stage to the evaluation stage.
The Evaluation stage is where the customer takes the time to compare your product to that which he is currently using. It is sometimes extremely difficult to change the habits of a customer, so persuasion and persistence is needed. Realizing where the customer is at within this sales cycle will help you to maintain perspective and use the appropriate sales skills to move him along the sales cycle. This is where your needs analysis is critical, as you want to ensure you are reinforcing, on a frequent basis, the benefits your product or service offers versus your competition in addressing THAT particular customer’s needs. To move the customer through this stage you need to present strong features and benefits, use excellent competitive selling techniques in addition to probing and strong skills.
In the final stage, the customer makes a Decision to use your product or service or your competitors. If he has chosen your product, you can feel good about taking your customer through the sales cycle and convincing him of the benefits of your product versus the competition. If the customer does not choose your product or service, then your job will be to take him back to the evaluation stage so he can re-evaluate the options and reconsider your product. Sometimes this is very difficult to do, as they may be very happy with what they are currently using. You may have to take them all the way back to the identification stage to find new opportunities or problems which your product can address and your competitor cannot. This is a very dynamic model, and each customer you deal with will be at a different stage in this cycle. It is your job to identify where that customer is and try to get him to the next stage using effective selling techniques.
Think of the sales cycle as a series of steps that you are climbing. Before you reach the top step (the sale), you have to walk the customer up each of the lower steps first. It is very rare that you will meet a customer for the first time and walk away with a sale. You need to complete the steps in the cycle and earn the right to ask for the business.
Another concept to keep in mind is that the time needed to move a customer through the sales cycle varies based on several factors:
1. Type of product – Healthcare sales products which are more expensive (such as capital equipment for use in hospitals) often requires consensus from a committee before the contract is signed. As a result, to get all members of the committee to agree takes quite a bit longer than a sale where only one customer needs to say “yes”.
2. Frequency of sales calls – The more frequently you are able to get face to face selling time with a customer, the quicker you will be able to move them through the sales cycle…IF you have developed excellent selling skills.
3. Representative selling skills – Without effective selling skills, you will not be able to move customers through the sales cycle. To move them more quickly through the sales cycle, you must continually develop and improve on all of the sales skills listed in this book.
Of the three listed here, representative selling skills is by far the most important one which affects the time needed to move a customer through the sales cycle.
The Customer Environment
Before we discuss each stage and the selling skills needed, we will consider the customer environment. The healthcare customer environment and selling into it requires a significant amount of planning, preparation, persistence and versatility to be effective. As you will learn, time is a very valuable commodity in the healthcare office or clinic, and making effective use of your time is critical to move that customer along the sales cycle to a decision which is favorable for your product or service. The key to success in this environment is ensuring you are calling on the right customer, the right number of times using the right message!
Why is it getting more difficult to get time with our customers?
Over the past several years, it has been getting more and more difficult to access customers in the healthcare industry, and those that can be accessed are giving less and less time to sales representatives. We will now have a look at some of the main reasons this is occurring:
1. Time Pressures – Today’s professionals try to squeeze more work into a day. Some physicians see between 30 and 60 patients per day. In addition to seeing patients, physicians need to finish patient charts, fill out insurance and lawyer’s reports, return phone calls and attend meetings. This is in addition to trying to have a life outside the office and spending quality time with their families. Five minutes with a representative is five minutes they could have spent completing other tasks.
2. Lack of Monetary Gain – Physicians do not get paid to see representatives but they do get paid to see patients. If they could see a patient in the time it takes to talk to a representative then they are losing money every time they talk to a representative. This reiterates the fact that you must provide value to your target customers on each and every call if you want to continue to get face time with them.
3. Number of Representatives – In many offices that see representatives, it is not uncommon for six or more representatives to visit on any given day. The sheer number representatives can be overwhelming, not only to the physician, but to the medical office assistants who have to deal with the patients in the waiting room.
4. Lack of Value Seen – This is the most important factor to keep in mind as you work on your territory. If a physician truly believes that seeing a particular sales representative will add value to his practice, he will take the time away from his patients to hear what that representative has to say. However, if he feels that a representative will bring no value, he will likely not spend any time with him or her. There can be various reasons for this, but the number one reason is that only the best representatives take the time to identify “true” needs of each customer and sell to that particular need. There are a lot of representatives who do not take the time to identify needs, involve the customer in the sales call, or prepare for each call to ensure value is seen every time. Without providing value to your key customers you will not be able to get adequate selling time to be effective.
Key Terms
To be most successful as a healthcare sales representative, you must understand two key terms: targeting and frequency.
Targeting: The Right Customer
When considering who your target customers are, there are two key questions to ask: how important is this customer to your business and how accessible is the customer to you?
How important is this customer to your business?
When considering this factor you need to look at not only how busy their practice is, but also what their patient demographics are. Yes, you must call on customers who see many patients per day, but if they are not the right types of patients for your products, then you are wasting your time. For example, if you are selling a medication for high blood pressure and you are calling on a busy physician who sees mainly younger women and children, this is not likely a good use of your time. It is crucial that you look at both how busy your customer is and what types of patients they most commonly treat. Generally speaking, the more patients a customer sees the better, as long as these are the types of patients your product will help.
How does a representative find out what types of patients a customer may see?
There are many ways including viewing the waiting room to profile the patients waiting to see the physician, looking to see what types of product samples are on the shelves, and asking the medical office assistant or local pharmacist what types of patients the area services. If all else fails, ask your physician! They will usually give you a straight up answer as to the types of patients they look after. Just remember, it’s not just the busy physicians who are important to you – they may be busy, but may not be seeing your targeted patient population. If this is the case, they may not be a true target physician for you.
How accessible is your customer?
If you have a customer who is extremely busy and services the types of patients that would be a great fit for your product, it makes sense that they should be a target for you. However, what if this physician is not willing to see you as a sales representative even though you have tried many ways to see him or her? In this situation, it may be wiser to take them off your target list and replace them with another customer that you have access to. However, it is important to remember that just because you have tried a couple of times to see this customer and have not had success, it does not mean they are not accessible. You need to try every means possible (using all of the activities you read about in the Introduction to the Pharmaceutical Sales Industry from PharmaCareer) to ensure that there is not some way that you can access this customer. There are many times a customer seems inaccessible but somehow, someway, you manage to make contact with them. These can end up being your best supporters as much of your competition may have given up calling on them, giving you the opportunity to sell to them in a less
competitive environment. It is important to remember that on average you will need to make contact with your targeted customers six to twelve times a year to make an impact. Seeing a customer once every two years is not going to make much of an impact on your sales!
Frequency: The Right Number of Times
A physician or other healthcare professional’s accessibility will affect another key aspect in healthcare sales, which is called frequency. Frequency is simply how often, or how many times during the course of a month, quarter, or year you should be in front of a customer selling your products’ messages. Frequency must be established for each target customer by realistically evaluating how often you can access that customer. Each customer you call on will have an effective frequency which you will identify over time and will dictate how you manage your sales territory on a day to day basis.
Not only do you have to call on your customers the right number of times with the right frequency and the right message, but you must identify which activities are best suited for each customer as there are many different ways of accessing them. Here is a list of activities that you can do with each of your customers or physicians. The goal is to find out who responds best to each activity and then use this knowledge to develop your business plan around each customer to ensure you are seeing them often enough to make an impact.
· appointments
· drop-in calls
· video lunches or lunch and learns
· journal clubs
· symposia
· CME (continuing medical education) programs
· conferences
· hospital rounds
· hospital displays
· business development or public relation events
Value or Needs Based Selling
The key to value selling is to ensure that you are selling based on what is important to your customer and
NOT just what is important to you. During the training process, you will be given every possible
advantage of the product you are going to be selling. The key to success on territory is finding which of
those advantages are most important for each individual physician you call on. Many sales trainers talk
about finding the physicians “hot button.” The hot button is a product’s features and benefits which are
most important to a particular physician. Many new representatives just out of training will do a “data
dump” or “product puke” which simply means trying to present two weeks of product training in five
minutes. Instead of doing this, spend time trying to find out what is important to your customer (using
your excellent probing skills) and then using the two or three features/benefits of your product that are
most relevant.
Consultative selling simply means selling as a consultant by involving your customer in discussion to
ensure you are talking about areas that are important to them. Most adults do not like being talked “to”
and would rather be involved in a discussion. Plus, this will allow you to gain much more information
than if you were doing all of the talking. Based on the information you have received through
consultative selling and probing, you will then use the appropriate sales tools to highlight the features and
benefits your product offers which best match the customer hot buttons.
Features and Benefits
Features are simply things that are built into a product or service and cannot be changed. Examples of
typical features of a healthcare sales product include: efficacy, safety and price. Efficacy answers the
question “does the product do what is says it will do?” If a medication was designed to lower cholesterol
by a certain percentage, efficacy is a measure of whether or not it does so in the manner described in the
literature and communicated by a sales representative. Comparing the efficacy of two medications by a
physician will often lead to him developing a preference for one over the other. Safety is another area
where products may differ. Safety is simply a comparison of the adverse effect profile between
medications (contraindications, cautions, side effects). Price is self explanatory. Products rarely cost the
same, and often higher priced products need to be sold more assertively to convince customers they are
worth the extra money paid.
Features by themselves do not sell a product. It is the benefit attached to a particular feature which will
impact the customer and sell your product. The benefit explains to the customer why a feature is
important and how it will help him, the patient, or the health care system. For example, consider a
product which costs one dollar a day for a patient. This feature ($1.00) will not sell the product.
However, the benefit may be that the price is 25% less than the competitor’s product and this means that
the physician’s patients (who may all live in a lower income neighborhood) may have more money in
their pockets for other living necessities. Conversely, the $1.00 price tag may be more than what the
competitors charge. However, your product may have data (which the other product does not have)
which shows it reduces heart attacks by 30% which means a savings to the total healthcare system. As a
sales representative, your goal is to find the feature that is MOST important to your customer (hot button)
and then focus on explaining how the benefits of this feature are better or more pronounced than the
competition.
When deciding whether or not you have presented a feature or a benefit, ask yourself “so what”? If there
is an answer to the “so what” question that you just asked yourself, then you may have presented a
feature and will need to go one step further to present a benefit. Keep asking yourself “so what” until
you really have trouble answering it. You need to take a benefit down to a very basic level and be able to
communicate it in a clear and effective way – using a visual aid to reinforce your message.
In addition, to make your features and benefits more impactful, many successful healthcare sales
representatives “paint the patient picture.” Painting the patient picture means helping the physician
visualize exactly which type of patient in his practice will most benefit from your product. If you do this
successfully, the next time that patient comes in, he or she may get your product and your sales will
increase.
Relationship between Sales and Marketing
Most people confuse between sales and marketing. It’s actually pretty straightforward: Marketers create
demand, and the sales team execute accordingly to fulfill that demand. Similar to design and marketing,
both teams share a symbiotic relationship – one cannot benefit without the other, yet they don’t speak the
same language. Each have their own jargons and lingoes they throw around one other, and it’s not
helping your company to grow. How can you put an end to the ceaseless sales and marketing dispute?
Let’s take a closer look at their dynamics.
We all know that poor communication discourages any form of relationship. A disconnect between your
teammates discourages your business efforts to maximize value for both your company and your
customers. Common conflicts include:
Losing focus
You may think that joint metrics in sales and marketing saves time, money, and energy. On the contrary,
this culture is exactly what’s causing that blurry distinction between sales and marketing – when they’ve
led a successful campaign, everyone shares the reward. When all else fails, team members blame one
another.
Separatistic culture
Each team is too focused on individual tasks. Marketers work out the grand plan, sales wants to close the
deal ASAP. Marketers work behind the desk, sales are out in the field. Marketers are strategic thinkers
who are highly analytical and data-oriented, and they’re motivated by providing creative solutions for the
long haul. Sales wants to generate maximum revenue as they’re usually compensated by commissions,
quotas, bonuses, and so on.
What about the customers?
We’re living in the digital era, and as a business leader it’s your responsibility for everyone in your team
to understand that consumers’ buying behaviors are changing.
For your product or service to successfully penetrate the new demand, you need to redesign your strategy
through a coherent series of campaigns, promotions, advertising, and other efforts.
This is where your marketing and salesforce must learn to cooperate, because no matter how brilliant the
plan is, your company will never profit when people simply don’t buy.
There are 4 essential steps a customer goes through before they decide to buy from you:
1. Awareness They know your existence. They look forward to seeing you again.
2. Consideration They go home and think about you – a sign that you’ve addressed their needs and
you promise to deliver.
3. Preference They like you more than your competitors, thanks to your excellent presentations and
proposals.
4. Conversion They’re ready to negotiate contracts and proceed to sales.
Converting leads to sales is tricky, and identifying qualified leads takes time. To foster strong customer
relationships, it takes a collaborative effort from every department of your company.
Teamwork: Two heads are better than one
True, your marketing plan should be solid, but it must also be flexible enough to integrate its
functions with the sales team. Similarly, salesforce must have a clear understanding of what is expected
out of each campaign.
When both teams start speaking the same language, they’re more engaged in executing every step of the
process from start to finish.
Align your sales and marketing operations to build on the following equities:
Loyalty This is the foundation for word-of-the-mouth marketing. At this point, your focus is to
educate and nurture first-time and regular customers. You’ve earned their trust, and you’ve got to
maintain that by giving quality service and continuous support.
Advocacy When customers are loyal to your brand, they help you build referrals for future
prospects. Consider it a success when your users, fans, and customers supports your brand more
than anything else.
In a nutshell, it’s your job as a leader to encourage effective communication among your teammates.
Instead of blaming one another, shift their focus on customers instead: What are their wants and needs?

INDIAN PHARMACEUTICAL INDUSTRY
Globalization is widely seen as a dominating phenomenon of 21st century encompassing worldwide
integration of financial systems, trade liberalization, deregulation and market opening resulting in a
global market and patterns of industrial development. In last few decades it is evident that firms and
institutions from peripheral countries or developing world are making sustained and deliberate effort to
take advantage of the new opportunities. The rise of East Asia followed by growth in China and India has
led to emergence of new breed of Multinational Enterprises (MNEs) from these countries. By the end of
2004 China emerged as fifth largest outward direct foreign investor with a total US $ 37 billion and was
the third largest exporter after Germany and the US (Child and Rodrigues, 2005). Similarly albeit on a
smaller scale in the last decade Indian economy saw a dramatic growth in overseas investment by the
Indian industry. The firms from latecomer countries are making inroads in sectors such as manufacturing
(steel and pharmaceuticals) and services (IT) and trading as well as high technology sectors like semi-
conductors. Some of the firms such as Infosys, Lenovo, Ranbaxy and Espat are now
competing at a global level. Multinational enterprises from developing countries are a clear
representation of a sustained increase in outward Foreign direct investment (FDI) from developing
countries which has risen from $60 billion in 1980 to $ 869 billion in 2000 and to a total in excess of
$1trillion for the first time in 2004 (UNCTAD, 2004). Outward FDI from developing countries accounts
for more than 10 percent of the world’s outward FDI. The rise of outward FDI and new MNEs that
embody it, from economies such as India, China, Korea, Singapore, Malaysia and Taiwan is a key
phenomenon for the world economy in last decade. It shows that firms from developing countries are
rising to compete at the frontiers of the world market and this research also focusing on the strategies
they have adopted to achieve that.
The first wave MNEs from the developing world documented by authors such as Kumar and mcleod
(1981) and Lall (1983) succeeded as international players despite many difficulties. Their success was
due as much to the difficulties encountered at home as to the incentives driving internationalization. One
of the most salient features of first wave MNE activity is the direction and motivation of FDI compared
to western MNEs. Much empirical work on first MNEs indicated strong and marked trend investments in
neighboring and other countries which were at a similar or earlier stage of their development. Prominent
first wave countries such as India, Philippines, Argentina and Columbia did not show any significant
increase in either the level of the total outward FDI, nor a significant shift towards developed country
hosts. But the arrival of the second wave MNEs from developing countries represents quite a different
phenomenon.
First wave countries experienced very low or negative economic growth rate whereas second wave
countries grew rapidly over the intervening decade and half. This has been further enhanced by
fundamental changes in the world economy which were a direct result of globalization. Globalization has
created a more broad and competitive market across countries due to convergence of production and
industrial patterns. As a result firms need to have 4 competitive advantages that are globally viable rather
than domestically. Most of these developing countries also went through a fundamental shift in the policy
orientation from an import substituting role to an export oriented outward economy. Firms in these
countries now faced competition in domestic market with global firms and needed upgrade their
capabilities to survive. These changes had a profound impact in creating a second wave of MNEs from
developing countries. Therefore Mathews (2006) argues that analysis of second wave requires different
perspectives that differ from those created to account for outward FDI from developed countries, and the
first wave of MNEs from developing countries. Initial analysis of second wave of MNEs reveals that
overseas move of firms in the second wave is a result of the ‘pull factors’ that are drawing firms into
global connections unlike ‘push factors’ that drove firms as stand alone players in the first wave
(Mathews, 2006). Dunning et al. (1997) suggest that in the case of second wave of MNEs from East-
Asian countries such as Taiwan and Korea were subsidized by governments with government policy
interacting with firm strategies. The rise of second wave MNEs from emerging countries is less driven by
cost factors per se, but more by a search for markets and technological innovations to compete
successfully in the Global economy (Yueng, 2000). The sudden appearance of the second wave of firms
and their capacity to create competitive positions to existing incumbents has raised interesting questions
as they are not simply occupying space vacated by incumbents instead in many cases they are creating
new economic space by their organizational and strategic innovation. Thus the changes in the world
economy, specifically its globally interlinked character is responsible for driving the new approaches to
and patterns of internationalization in firms from peripheral countries. Therefore Mathews (2006)
suggests that existing theories and framework of internationalization have failed to capture organization
and strategic innovations adopted by developing country MNEs for new modes of internationalization. In
this context the Indian pharmaceutical industry provides an ideal case to investigate approaches and
motives of second wave MNEs firms from developing countries. From the beginning of the 1990s, the
Indian government started liberalization by removing restrictions on trade such as regulations on FDI and
opened Indian market to overseas firms. As a result of liberalization policy Indian Economy witnessed
dramatic growth, changes in domestic market and firm activities specifically in relation to overseas
expansion strategies. The cumulative number of overseas project approved during the 1990s is estimated
to be 2652, a nearly 11 fold increase from the number of projects permitted during 1975-90 (230)
(Pradhan,2004). The growth of overseas investment is been characterized by significant changes in
location and sectoral distribution. In the 1990s the majority of investments has originated from the
service sector and was increasingly developed country-oriented with majority ownership in most cases.
The most important destination of Indian outward FDI to date is the USA which accounted for 19% of
total cumulative outflows from 1996-2003.
In 2005 Indian firms acquire 136 firms overseas with a total value of US $4.3 billion. The Indian
pharmaceutical Industry is at the forefront in international expansion compared to other manufacturing
sectors in the Indian Economy.
The Indian pharmaceutical industry is the thirteenth largest in the world in terms of market output;
accounting for a market of about US$ 2.5 billion (Ramani, 2002). It is ranked as the most advanced
pharmaceutical industry amongst developing countries and is one of India’s best science-based industries.
Indian firms have been investing abroad for many years but it is only since the late-1990s that outward
FDI flows have risen considerably. The liberalization of government policies and relaxation of
regulations on FDI abroad have helped Indian firms to expand internationally. In the last decade some
Indian pharmaceutical firms have successfully internationalized their operations and emerged as a major
producers and suppliers of generic drugs all over the world. This study of internationalization motives
and strategies adopted by Indian Pharmaceutical firms. In the absence of more systematic longitudinal
firm level data this research is based on case study evidence. The findings suggest that Indian
pharmaceutical firms are accessing advanced markets and acquiring new technology through the process
of internationalization. Indian firms augmenting existing skills in production capabilities and process
R&D by acquiring technology focused firms in advance markets. The analysis suggests that Indian
pharmaceutical firms have adapted to the realities of globalization and are finding new niche through the
process of internationalization.
The Indian pharmaceutical industry:
India currently represents just US $6 billion of the $550 billion global pharmaceutical industry, its share
is increasing at 10 % a year. The organized sector of India’s pharmaceutical industry consists of 250 to
300 companies, which accounts for 70 % of the market, with the top ten companies representing 30%.
The Indian pharmaceutical industry has developed wide ranging capabilities in the complex field of drug
process
Development and production technology. It is well ahead of other developing countries in process R&D
capabilities and the range of technologically complex medicines manufactured. The Indian government
adopted a new Patents Act in 1970, which laid the foundations of the modern Indian Pharmaceutical
industry. It removed product patents for pharmaceuticals, food and agro-chemicals, allowing patents only
for production processes. The statutory term for production processes was shortened to five years from
grant or seven years from application. The 1970 Patent Act greatly weakened intellectual property
protection in India, particularly for pharmaceutical innovations. It started the era of reverse engineering
where firms developed new products by changing their production processes like Dr. Reddy. Trained
manpower, comparative ease of imitation and a strong chemistry base among Indian research institutes
supported manufacturers and gave the
Indian pharmaceutical industry its current profile. The industry’s exports were worth more than US $
492.30 in 2005-06 and they have been growing at a compound annual rate of 22.7 percent over the last
few years (National pharmaceutical policy, 2006).
The value of the Indian Pharmaceutical industry’s overseas acquisition has grown from just US $8
million in 1997 to $116 million in 2004. Indian firms have acquired over US $1 billion worth of
pharmaceutical companies overseas in 2005. There are 3 developments which are pushing expansion of
the Indian pharmaceutical industry into overseas markets;
A. Opportunities opened in the US generic market due to the Hatch-Waxman Act,
B. Increasing outsourcing by MNC pharmaceutical firms and
C. Strengthening of patent laws in the domestic market.
D. Implement all these techniques in India for producing good medicines.
These three developments are creating new challenges and opportunities for Indian industry and
internationalization is one of route adopted by Indian to succeed in this new
environment. The generic opportunity is a result of the passing of the Hutch Waxman Act in the US in
1984. Under this new law, manufacturers of generic drugs no longer had to go through a lengthy period
of extensive clinical trials in order to market a generic drug - demonstration of bio-equivalence was
sufficient to acquire a patent on a generic drug. procedures were established for the resolution of disputes
between branded drug manufacturers and generic manufacturers. Western markets were a lucrative
business opportunity and the low cost advantage enjoyed by Indian firms on account of the cheap
availability of scientific labour combined with scale economies inherent in the manufacture of bulk
chemicals made for big margins. Between 1999 and 2005 drugs worth $ 64 million went off patent
allowing generic companies to take advantage of better business opportunities. In the generics industry
prescription drugs worth $40 billion in the US and $25 billion in Europe are due to loose patent
protection by 2007-08. In 2004 the US senate passed the Greater Access to Affordable Medicine Act
diluting some of the proinnovator provisions of 1984 Hatch-Waxman Act, giving a big boost to the
generic business in the US. Similarly Europe is emerging as a key market and a potential growth driver.
The size of market in 2006 was US $ 14.2 billion with Germany, France, the UK and Italy accounting for
more than 50% of market. Governments in Europe are trying to reduce healthcare costs by embracing
generic drug companies. Liberalization facilitated the ability of Indian firms to exploit this opportunity to
market generics drugs to the US and other Western economies. Indian firms are preparing themselves to
take a share of this increasing global market. Indian drug manufacturers
currently export their products to more than 65 countries worldwide; the US being the largest customer.
However Indian firms face some difficult challenges such as non tariff barriers, decreasing profits in the
generics market, competitive threats from big pharma MNEs and reputation in western markets. For
example, US regulation disqualifies Indian firms from bidding for government contracts and Indian firms
have to submit separate
Applications for each state even when firms have FDA approved products and facilities. Another
challenge is the reduction in profit margin due to intense competition from Chinese and Eastern European
manufacturers as well as authorized generics produced by main manufacturer. Currently Indian industry
is estimated to account for 22% of generics in the world market. Indian firms are aiming to move up the
value chain by developing capabilities to produce ‘super generics’ rather than ‘generics generics’ to
branded generics.
Furthermore, stronger patent protection under the new patent law of 1999 has shut down the avenues for
exploitation of generics opportunity in domestic market, but promised large rewards to Indian firms that
could leverage their reverse engineering capabilities in advanced markets. The stronger patent law
restricts reverse engineering of newly patented molecule, thus affecting an important source of growth for
Indian firms. Also
multinational pharmaceutical firms have entered India after 2005 and using the same resource base as
Indian firms to compete in the Indian domestic market further increasing pressure on profit margins of
Indian firms. The contract research and manufacturing services (CRAM) market has emerged as huge
opportunity for the Indian pharmaceutical industry. According to Frost and Sullivan (2005), the global
outsourcing market is worth
$37 billion and growing at almost 11%; 50% of the contract manufacturing market is in North America,
40% in Europe and just 10% in Asia and the rest of the world. Indian firms possess requisite capabilities
to cater for the requirements of outsourcing markets, still India accounts for barely 1.5% of the global
CRAM industry. Due to untested patent protection law and lack of data protection MNC firms are
reluctant to outsource early stage R&D work to Indian firms. Therefore Indian firms are trying to
increase their share in the outsourcing market by moving closer to the market.
Geographically the overseas acquisition by Indian pharmaceutical firms continues to be directed at
developed countries specifically the US and Europe (Table 1). Out of 32 acquisitions listed in Table 1
only 6 are in developing markets and the remaining rest of 26 are in advanced markets such as the US
and Europe. The major acquisitions are in the area of marketing although some companies are investing
in building manufacturing and
R&D capacities in developed markets. Indian companies have already established manufacturing plants
in the US, Europe, Brazil, Russia and China.

The major Indian companies such as Ranbaxy, Dr. Reddy’s Laboratories, Wockhardt and others have
established their own brand image in the international market as well as domestic market and are taking
steps to consolidate their activities.
Indian firms are compensating for the spiraling cost of selling and marketing in advance countries by
setting wholly owned subsidiaries or acquiring local firm. Thus reinforcing the argument that Indian
firm’s internationalization through acquisition is directed towards acquiring new knowledge in different
areas such as R&D capabilities, regulatory skills and distribution networks.
3. Firms under investigation
The findings of this research are based on the study of internationalization motives and patterns adopted
by five well established Indian pharmaceutical firms, viz. Ranbaxy Laboratories, Dr. Reddy’s Labs,
Wockhardt, Nicholas Piramal and Sun Pharmaceuticals Ltd.

Omeprazole (INN) (pron.: / oʊ ̍ m ɛ p r ə z oʊ l / ) (Prilosec and generics) is a proton pump inhibitor used in the
treatment of dyspepsia, peptic ulcer disease (PUD), gastroesophageal reflux disease (GORD/GERD),
laryngopharyngeal reflux (LPR) and Zollinger–Ellison syndrome. Omeprazole is one of the most widely
prescribed drugs internationally and is available over the counter in some countries.
Medical uses
See also: Proton pump inhibitor
Used to treat GERD (gastroesophageal reflux disease), gastric and duodenum ulceration and gastritis.
As a therapeutic adjuvant in treating Helicobacter pylori related ulcers
Omeprazole is combined with the antibiotics clarithromycin and amoxicillin (or metronidazole in
penicillin-hypersensitive patients) in the 7–14 day eradication triple therapy for Helicobacter pylori.
Infection by H. pylori is the causative factor in the majority of peptic ulcers.[3]
Adverse effects
Some of the most frequent side effects of omeprazole (experienced by over 1% of those taking the drug)
are headache, diarrhea, abdominal pain, nausea, dizziness, trouble awakening and sleep deprivation,
although in clinical trials the incidence of these effects with omeprazole was mostly comparable to that
found with placebo.[4] Other side effects may include iron and vitamin B12 deficiency, although there is
very little evidence to support this.[5]
Proton pump inhibitors may be associated with a greater risk of osteoporosis related fractures[6][7] and
Clostridium difficile-associated diarrhea.[5][8] Antacid preparations (such as omeprazole), by suppressing
acid-mediated breakdown of proteins, lead to an elevated risk of developing food and drug allergies. This
happens due to undigested proteins then passing into the gastrointestinal tract where sensitisation occurs.
It is unclear whether this risk occurs with only long-term use or with short-term use as well.[9] Patients are
frequently administered the drugs in intensive care as a protective measure against ulcers, but this use is
also associated with a 30% increase in occurrence of pneumonia.[5][10] The risk of community-acquired
pneumonia may also be higher in people taking PPIs.[5]
Since their introduction, proton pump inhibitors (especially omeprazole) have been associated with
several cases of acute tubulointerstitial nephritis, an inflammation of the kidneys that often occurs as an
adverse drug reaction.[5][11][12]
PPI use has also been associated with fundic gland polyposis.[13]
The following adverse reactions have been identified during post-approval use of Prilosec Delayed-
Release Capsules.[14] Because these reactions are voluntarily reported from a population of uncertain size,
it is not always possible to reliably estimate their actual frequency or establish a causal relationship to
drug exposure.
Systemic: Hypersensitivity reactions including anaphylaxis, anaphylactic shock, angioedema,
bronchospasm, interstitial nephritis, urticaria, fever; pain; fatigue; malaise;hair loss;
Cardiovascular: Chest pain or angina, tachycardia, bradycardia, palpitations, elevated blood pressure,
peripheral edema
Endocrine: Gynecomastia
Gastrointestinal: Pancreatitis (some fatal), anorexia, irritable colon, fecal discoloration, esophageal
candidiasis, mucosal atrophy of the tongue, stomatitis, abdominal swelling, dry mouth, microscopic
colitis. During treatment with omeprazole, gastric fundic gland polyps have been noted rarely. These
polyps are benign and appear to be reversible when treatment is discontinued. Gastroduodenal carcinoids
have been reported in patients with ZE syndrome on long-term treatment with Prilosec. This finding is
believed to be a manifestation of the underlying condition, which is known to be associated with such
tumors.
Hepatic: Liver disease including hepatic failure (some fatal), liver necrosis (some fatal), hepatic
encephalopathy hepatocellular disease, cholestatic disease, mixed hepatitis, jaundice, and elevations of
liver function tests [ALT, AST, GGT, alkaline phosphatase, and bilirubin]
Metabolism and Nutritional disorders: Hypoglycemia, hypomagnesemia, hyponatremia, weight gain
Musculoskeletal: Muscle weakness, myalgia, muscle cramps, joint pain, leg pain, bone fracture
Nervous System/Psychiatric: Psychiatric and sleep disturbances including depression, agitation,
aggression, hallucinations, confusion, insomnia, nervousness, apathy, somnolence, anxiety, and dream

Interactions
Omeprazole is a competitive inhibitor of the enzymes CYP2C19 and CYP2C9, and may therefore
interact with drugs that depend on them for metabolism, such as diazepam, escitalopram, and warfarin;
the concentrations of these drugs may increase if they are used concomitantly with omeprazole. [15]
Clopidogrel (Plavix) is an inactive prodrug that partially depends on CYP2C19 for conversion to its
active form; inhibition of CYP2C19 blocks the activation of clopidogrel, thus reducing its effects and
potentially increasing the risk of stroke or heart attack in people taking clopidogrel to prevent these
events.[16][17] Omeprazole is also a competitive inhibitor of p-glycoprotein, as are other PPIs.[18]
Drugs that depend on stomach pH for absorption may interact with omeprazole; drugs that depend on an
acidic environment (such as ketoconazole or atazanavir) will be poorly absorbed, whereas acid-labile
antibiotics (such as erythromycin) will be absorbed to a greater extent than normal due to the more
alkaline environment of the stomach.[15]
St. John's wort (Hypericum perforatum) and Gingko biloba significantly reduce plasma concentrations of
omeprazole through induction of CYP3A4 and CYP2C19.[19]
Mechanism of action
Omeprazole is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the
H+/K+-ATPase in the gastric parietal cell. By acting specifically on the proton pump, omeprazole blocks
the final step in acid production, thus reducing gastric acidity.[20]
Pharmacokinetics
The absorption of omeprazole takes place in the small intestine and is usually completed within 3–6
hours. The systemic bioavailability of omeprazole after repeated dose is about 60%.
Omeprazole bioavailability is significantly impaired by the presence of food and, therefore, patients
should be advised to take omeprazole with a glass of water on an empty stomach (i.e., fast for at least 60
minutes before taking omeprazole). Additionally, most sources recommend that after taking omeprazole
at least 30 minutes should be allowed to elapse before eating [21][22] (at least 60 minutes for immediate-
release omeprazole plus sodium bicarbonate products, such as Zegerid[23]), though some sources say that
with delayed-release forms of omeprazole it is not necessary to wait before eating after taking the
medication.[24] Plasma protein binding is about 95%.
Omeprazole is completely metabolized by the cytochrome P450 system, mainly in the liver. Identified
metabolites are the sulfone, the sulfide and hydroxy-omeprazole, which exert no significant effect on acid
secretion. About 80% of an orally given dose is excreted as metabolites in the urine and the remainder is
found in the feces, primarily originating from bile secretion.
Measurement in body fluids
Omeprazole may be quantitated in plasma or serum to monitor therapy or to confirm a diagnosis of
poisoning in hospitalized patients. Plasma omeprazole concentrations are usually in a range of 0.2–
1.2 mg/L in persons receiving the drug therapeutically via the oral route and 1–6 mg/L in victims of acute
overdosage. Enantiomeric chromatographic methods are available to distinguish esomeprazole from
racemic omeprazole.[25][26]
Chemistry
(S)- and (R)-enantiomers of omeprazole, a racemate (1:1 mixture of both enantiomers)
Omeprazole is a racemate. It contains a tricoordinated sulfinyl sulfur in a pyramidal structure and
therefore can exist in equal amounts of both the (S)- and (R)-enantiomers. In the acidic conditions of the
canaliculi of parietal cells, both are converted to achiral products (sulfenic acid and sulfenamide
configurations) which reacts with a cysteine group in H + /K + ATPase , thereby inhibiting the ability of the
parietal cells to produce gastric acid.
Facing the loss of patent protection and competition from generic drug manufacturers, AstraZeneca
developed and heavily marketed esomeprazole (Nexium) as a replacement in 2001.[when?] Esomeprazole is
the eutomer [(S)-enantiomer] in the pure form, not a racemate like omeprazole.
Omeprazole undergoes a chiral shift in vivo which converts the inactive (R)-enantiomer to the active (S)-
enantiomer doubling the concentration of the active form.[27] This chiral shift is accomplished by the
CYP2C19 isozyme of cytochrome P450, which is not found equally in all human populations. Those who
do not metabolize the drug effectively are called "poor metabolizers." The proportion of the poor
metabolizer phenotype varies widely between populations, from 2–2.5% in African-Americans and white
Americans to >20% in Asians; several pharmacogenomics studies have suggested that PPI treatment
should be tailored according to CYP2C19 metabolism status.[28]
History
Omeprazole was first marketed in the U.S. in 1989 by Astra AB, now AstraZeneca under the brand
names Losec and Prilosec. An over the counter brand, Prilosec OTC, is available without prescription in
the US for treatment of heartburn. It is now also available from generic manufacturers under various
brand names.
In 1990, at the request of the U.S. Food and Drug Administration (FDA), the brand name Losec was
changed to Prilosec to avoid confusion with the diuretic Lasix (furosemide).[29] The new name has led to
confusion between omeprazole (Prilosec) and fluoxetine (Prozac), an antidepressant.[29]
AstraZeneca markets omeprazole as Losec, Antra, Gastroloc, Mopral, Omepral, and Prilosec.
Omeprazole is marketed as Zegerid by Santarus, Prilosec OTC by Procter & Gamble and Zegerid OTC
by Schering-Plough and as Segazole by Star Laboratories in Pakistan.[30][31] In the Philippines, Ajanta
Pharma markets omeprazole under the brand name Zegacid. Dr. Reddy's Laboratories markets it as Omez
in India, Russia, Romania, and South Africa. In Bangladesh Healthcare Pharmaceuticals Ltd. marketed
omeprazole under the brand name Opal. In Bangladesh Apex Pharma also markets omeprazole under the
brand name Aspra. It is also available under the brand name Rome 20 marketed by Rephco
Pharmaceuticals Ltd. In Bangladesh the brand leader in this market is Seclo. In Argentina it is made by
Bago Laboratories S.A. and available there and in Ecuador as Ulcozol. In Indonesia Darya-Varia
Laboratories marketed omeprazole as Ozid. In Brazil, omeprazole is produced by Multilab under the
name Lozeprel. In Spain it is produced by Cantabria Pharma S.L. under the name emeprotón. In
Bangladesh, Eskayef Bangladesh Limited also marketed omeprazole under the brand name Losectil. The
Acme Laboratories Limited marketed it under the brand name PPI.
In 1999, antiulcerants were the leading class of therapeutic drugs, with $15.6 billion in global sales. Of
that, Prilosec accounted for $5.91 billion, making it the best-selling drug on the market.[32]
Although Prilosec's U.S. patent expired in April 2001, AstraZeneca was able to delay the introduction of
generic versions through lawsuits and peripheral patent claims. It introduced Nexium as a patented
replacement drug.[33]

Package of Losec (Omeprazole) 20 mg, purchased in Hong Kong
Omeprazole 10 mg, From U.K.
Omeprazole is available as tablets and capsules (containing omeprazole or omeprazole magnesium) in
strengths of 10 mg, 20 mg, 40 mg, and in some markets 80 mg; and as a powder (omeprazole sodium) for
intravenous injection. Most oral omeprazole preparations are enteric-coated, due to the rapid degradation
of the drug in the acidic conditions of the stomach. This is most commonly achieved by formulating
enteric-coated granules within capsules, enteric-coated tablets, and the multiple-unit pellet system
(MUPS).
It is also available for use in injectable form (I.V.) in Europe, but not in the U.S. The injection pack is a
combination pack consisting of a vial and a separate ampule of reconstituting solution. Each 10 ml clear
glass vial contains a white to off-white lyophilised powder consisting of omeprazole sodium 42.6 mg
equivalent to 40 mg of omeprazole.
Multiple unit pellet system
Omeprazole tablets manufactured by AstraZeneca (notably Losec/Prilosec) are formulated as a "multiple
unit pellet system" (MUPS). Essentially, the tablet consists of extremely small enteric-coated granules
(pellets) of the omeprazole formulation inside an outer shell. When the tablet is immersed in an aqueous
solution, as happens when the tablet reaches the stomach, water enters the tablet by osmosis. The
contents swell from water absorption causing the shell to burst, releasing the enteric-coated granules. For
most patients, the multiple-unit pellet system is of no advantage over conventional enteric-coated
preparations. Patients for which the formulation is of benefit include those requiring nasogastric tube
feeding and those with difficulty swallowing (dysphagia) because the tablets can be mixed with water
ahead of time, releasing the granules into a slurry form, which is easier to pass down the feeding tube or
to swallow than the pill.[citation needed] The granules are manufactured in a fluid air bed system. Sugar spheres
in suspension are sequentially sprayed with aqueous suspensions of omeprazole, a protective layer, an
enteric coating and an outer layer to reduce granule aggregation. The granules are mixed with other
excipients and compressed into tablets. Finally, the tablets are film-coated to improve the stability and
appearance of the preparation. Also available in a liquid suspension form, from a compounding
pharmacy. Ideal for infants.
Immediate release formulation
In June 2004 the FDA approved an immediate release preparation of omeprazole and sodium bicarbonate
that does not require an enteric coating. This preparation employs sodium bicarbonate as a buffer to
protect omeprazole from gastric acid degradation. This allows for the production of chewable tablets.
This combination preparation is marketed in the United States by Santarus under the brand name Zegerid.
Zegerid is marketed as capsules, chewable tablets, and powder for oral suspension. Zegerid is most useful
for those patients who suffer from nocturnal acid breakthrough (NAB) or those patients who desire
immediate relief. In India it is marketed by Dr. Reddy's Laboratories as powder formulation with the
brand name OMEZ-INSTA. It is reported to have additional benefits with patients suffering from
alcoholic gastritis and life-style associated gastritis.
BRAND SELECTION
Basis of Selction Of Brands
This study was taken up as the customer centric approaches and it was kept in mind as to what
parameters do customer question while selection of a brand and thus, ultimately result as a major factor
affecting the customer over all evaluation process. The company’s interpretation is what is explained in
the following text –
1. Brand rejection.
If someone associates a brand with something negative, they will purposely avoid the
product. Have you ever experienced bad service somewhere and swore you'd never return to that
chain? Have any of your customers said that about your business? Create a logo and slogan that is
filled with great benefits to your customer and put that on everything. If public opinion is turning
against you or your product, launch a campaign to alter it.
2. Brand non-recognition.
This is where your customers simply don't recognize your brand, probably because it is
not clearly differentiated from competitors. Boldly state your product or service's benefits.
Always include the full trademark name whenever you refer to your product. Be willing to create
brand names for your products or services, just like you've done for your own business. Find the
differences in value between your product and your competitors and highlight that difference
mercilessly.
3. Brand recognition.
This is a good stage to aim for if you don't have any recognition at all. Brand recognition will
help people lean toward your product when given the choice between your product and one they have
never heard of. At the same time, though remember that your competitors are also working on brand
recognition, which means their brand could be more recognizable. Continue to differentiate yourself
and be sure to add value to your product in order to get to the next stage.
4. Brand preference.
This is where customers - given a choice between two brands - will choose yours over
someone else's. It often is the result of a sense of differentiation and that your product or service
uniquely serves their needs. As well, you can be sure that any value-added products or services you
include help them to choose yours over your competitors. Even though this is a great stage to be in,
it's not the final stage. The stage you absolutely want to be in with your brand is!
5. Brand loyalty.
This is where customers will choose your brand time and time again, even if they experience
the occasional poor service or if another product comes along that seems to be better suited to their
needs. To achieve brand loyalty, you need to provide a product that is highly differentiated, with
plenty of value added, but also you need to offer them remarkable service at a level they will not get
anywhere else. Providing this level of service will ensure that they will never switch.

The
company is the fifth largest pharmaceutical company in India, [1] with US$290m in
turnover in 2004. It is a significant manufacturer of generic drugs.
Cadila Laboratories was founded in 1952 by Shri Ramanbhai Patel (1925-2001), formerly
a lecturer in the L.M. College of Pharmacy, and his business partner Shri Indravadan
Modi. The company evolved over the next four decades into one of India's established
pharmaceutical companies.
In 1995 the Patel and Modi families split, with the Modi family's share being
moved into a new company called Cadila Pharmaceuticals Ltd. and Cadila Healthcare
became the Patel family's holding company. Cadila Healthcare did its IPO on the Bombay
Stock Exchange in 2000. Its stock code on the Bombay exchange is 532321.
In 2001 the company acquired another Indian pharmaceutical company called
German Remedies. On June 25, 2007, the company signed an agreement to acquire 100
per cent stake in Brazils Quimica e Farmaceutica Nikkho do Brasil Ltda (Nikkho) for
around 26 million dollars.

Dosage forms:
Omeprazole is available as tablets and capsules (containing omeprazole or omeprazole magnesium) in
strengths of 10 mg, 20 mg, 40 mg, and in some markets 80 mg; and as a powder (omeprazole sodium) for
intravenous injection. Most oral omeprazole preparations are enteric-coated, due to the rapid degradation
of the drug in the acidic conditions of the stomach. This is most commonly achieved by formulating
enteric-coated granules within capsules, enteric-coated tablets, and the multiple-unit pellet system
(MUPS).
It is also available for use in injectable form (I.V.) in Europe, but not in the U.S. The injection pack is a
combination pack consisting of a vial and a separate ampule of reconstituting solution. Each 10 ml clear
glass vial contains a white to off-white lyophilised powder consisting of omeprazole sodium 42.6 mg
equivalent to 40 mg of omeprazole.
Synthesis:
preparation of omeprazole which comprises the steps of:
# (i) converting 4-nitro-2,3,5-trimethyl pyridine-N-oxide (I) to 4-nitro-3,5-dimethyl-2-(X-substituted
methyl) pyridine (II) where X is halogen
# (ii)
reacting (II) with a substituted benzimidazole of formula (III) to make a compound of formula (IV):
# (iii) converting compound (IV) to compound (V) by replacing the nitro group with a methoxy group:
# (iv) and oxidising (V) to form omeprazole (VI)
Preferably, in step (i), the compound I is acetylated to form 4-nitro-3,5-dimethyl-2-
acetoxymethylpyridine (Ia) which, after hydrolysis to compound Ib, is halogenated to form the 2-
halomethyl derivative (II): where X is halogen.
EP-A-484265 discloses a similar process, but with key differences. At page 32 of EP-A- 484265,
production of omeprazole from the intermediate is described, but the N-oxide moiety is retained until
after the condensation reaction with 5-methoxy-2-mercapto-benzimidazole has been performed, thus
requiring a subsequent deoxygenation step.
In the above preferred procedure for step (i), the intermediate compounds Ia and Ib are preferably not
isolated from the reaction mixture. Also, compound II need not be isolated.
In the most preferred step (i), the acetylation is effected using acetic anhydride, and the halogenation is
effected using thionyl chloride. However, other suitable reactants can be used for each of these reactions.
Step (ii) of the process is preferably effected in the presence of sodium hydroxide and a phase transfer
catalyst such as, for example, a quaternary ammonium salt, especially one selected from triethyl benzyl
ammonium chloride, tetrabutyl ammonium bromide, tetrabutyl ammonium hydrogen sulphate and
cetrimide.
Step (iii) of the process of the invention is preferably effected using a mixture of methanol, sodium
methoxide and potassium carbonate. However, other reactants can be used such as, for example,
potassium hydroxide, sodium hydroxide and potassium bicarbonate. In the most preferred method of
performing step (iii), compound IV is reacted with potassium carbonate and sodium methoxide in
methanol in the presence of catalytic amounts of anhydrous zinc chloride or magnesium chloride at a
temperature above 45°C, preferably at the reflux temperature of methanol.
In step (iv) of the process, the compound of formula V is oxidised to form omeprazole.
Mechanism of Action:
Omeprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress
gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface
of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the
gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the
final step of acid production. This effect is dose-related and leads to inhibition of both basal and
stimulated acid secretion irrespective of the stimulus. Animal studies indicate that after rapid
disappearance from plasma, omeprazole can be found within the gastric mucosa for a day or more.
Animal Pharmacology
Pharmacodynamics:
Antisecretory Activity:
After oral administration, the onset of the antisecretory effect of omeprazole occurs within one hour, with
the maximum effect occurring within two hours. Inhibition of secretion is about 50% of maximum at 24
hours and the duration of inhibition lasts up to 72 hours. The antisecretory effect thus lasts far longer than
would be expected from the very short (less than one hour) plasma half-life, apparently due to prolonged
binding to the parietal H+/K+ ATPase enzyme. When the drug is discontinued, secretory activity returns
gradually, over 3 to 5 days. The inhibitory effect of omeprazole on acid secretion increases with repeated
once-daily dosing, reaching a plateau after four days.
Results from numerous studies of the antisecretory effect of multiple doses of 20 mg and 40 mg of
omeprazole in normal volunteers and patients are shown below. The “max” value represents
determinations at a time of maximum effect (2-6 hours after dosing), while “min” values are those 24
hours after the last dose of omeprazole.
Serum Gastric Effects
In studies involving more than 200 patients, serum gastrin levels increased during the first 1 to 2 weeks
of once-daily administration of therapeutic doses of omeprazole in parallel with inhibition of acid
secretion. No further increase in serum gastrin occurred with continued treatment. In comparison with
histamine H2-receptor antagonists, the median increases produced by 20 mg doses of omeprazole were
higher (1.3 to 3.6 fold vs. 1.1 to 1.8 fold increase). Gastrin values returned to pretreatment levels, usually
within 1 to 2 weeks after discontinuation of therapy.
Enterochromaffin-like (ECL) Cell Effects
Human gastric biopsy specimens have been obtained from more than 3000 patients treated with
omeprazole in long-term clinical trials. The incidence of ECL cell hyperplasia in these studies increased
with time; however, no case of ECL cell carcinoids, dysplasia, or neoplasia has been found in these
patients. However, these studies are of insufficient duration and size to rule out the possible influence of
long-term administration of omeprazole on the development of any premalignant or malignant
conditions.
Other Effects
Systemic effects of omeprazole in the CNS, cardiovascular and respiratory systems have not been found
to date. Omeprazole, given in oral doses of 30 or 40 mg for 2 to 4 weeks, had no effect on thyroid
function, carbohydrate metabolism, or circulating levels of parathyroid hormone, cortisol, estradiol,
testosterone, prolactin, cholecystokinin or secretin.
No effect on gastric emptying of the solid and liquid components of a test meal was demonstrated after a
single dose of omeprazole 90 mg. In healthy subjects, a single I.V. dose of omeprazole (0.35 mg/kg) had
no effect on intrinsic factor secretion. No systematic dose-dependent effect has been observed on basal or
stimulated pepsin output in humans.
However, when intragastric pH is maintained at 4.0 or above, basal pepsin output is low, and pepsin
activity is decreased.
As do other agents that elevate intragastric pH, omeprazole administered for 14 days in healthy subjects
produced a significant increase in the intragastric concentrations of viable bacteria. The pattern of the
bacterial species was unchanged from that commonly found in saliva. All changes resolved within three
days of stopping treatment.
Pharmacokinetics
Absorption and Distribution:
OMEPRAZOLE Delayed-Release Capsules contain an enteric-coated granule formulation of omeprazole
(because omeprazole is acid-labile), so that absorption of omeprazole begins only after the granules leave
the stomach. Absorption is rapid, with peak plasma levels of omeprazole occurring within 0.5 to 3.5
hours. Peak plasma concentrations of omeprazole and AUC are approximately proportional to doses up to
40 mg, but because of a saturable first-pass effect, a greater than linear response in peak plasma
concentration and AUC occurs with doses greater than 40 mg. Absolute bioavailability (compared with
intravenous administration) is about 30-40% at doses of 20-40 mg, due in large part to presystemic
metabolism. In healthy subjects the plasma half-life is 0.5 to 1 hour, and the total body clearance is 500-
600 mL/min.
Based on a relative bioavailability study, the AUC and Cmax of OMEPRAZOLE (omeprazole
magnesium) for Delayed-Release Oral Suspension were 87% and 88% of those for OMEPRAZOLE
Delayed-Release Capsules, respectively.
The bioavailability of omeprazole increases slightly upon repeated administration of OMEPRAZOLE
Delayed-Release Capsules.
OMEPRAZOLE Delayed-Release Capsule 40 mg was bioequivalent when administered with and without
applesauce. However, OMEPRAZOLE Delayed-Release Capsule 20 mg was not bioequivalent when
administered with and without applesauce. When administered with applesauce, a mean 25% reduction in
Cmax was observed without a significant change in AUC for OMEPRAZOLE Delayed-Release Capsule
20 mg. The clinical relevance of this finding is unknown.
Distribution
Protein binding is approximately 95%.
Metabolism:
Omeprazole is extensively metabolized by the cytochrome P450 (CYP) enzyme system.
Excretion:
Following single dose oral administration of a buffered solution of omeprazole, little if any unchanged
drug was excreted in urine. The majority of the dose (about 77%) was eliminated in urine as at least six
metabolites. Two were identified as hydroxyomeprazole and the corresponding carboxylic acid. The
remainder of the dose was recoverable in feces. This implies a significant biliary excretion of the
metabolites of omeprazole. Three metabolites have been identified in plasma — the sulfide and sulfone
derivatives of omeprazole, and hydroxyomeprazole. These metabolites have very little or no antisecretory
activity.
Side Effects:
The safety data described below reflects exposure to OMEPRAZOLE Delayed-Release Capsules in 3096
patients from worldwide clinical trials (465 patients from US studies and 2,631 patients from
international studies). Indications clinically studied in US trials included duodenal ulcer, resistant ulcer,
and Zollinger-Ellison syndrome. The international clinical trials were double blind and open-label in
design. The most common adverse reactions reported (i.e., with an incidence rate ≥ 2%) from
OMEPRAZOLE-treated patients enrolled in these studies included headache (6.9%), abdominal pain
(5.2%), nausea (4.0%), diarrhea (3.7%), vomiting (3.2%), and flatulence (2.7%).
Additional adverse reactions that were reported with an incidence ≥ 1% included acid regurgitation
(1.9%), upper respiratory infection (1.9%), constipation (1.5%), dizziness (1.5%), rash (1.5%), asthenia
(1.3%), back pain (1.1%), and cough (1.1%).
The clinical trial safety profile in patients greater than 65 years of age was similar to that in patients 65
years of age or less.
The clinical trial safety profile in pediatric patients who received OMEPRAZOLE Delayed-Release
Capsules was similar to that in adult patients. Unique to the pediatric population, however, adverse
reactions of the respiratory system were most frequently reported in both the 1 to < 2 and 2 to 16 year age
groups (75.0% and 18.5%, respectively). Similarly, fever was frequently reported in the 1 to 2 year age
group (33.0%), and accidental injuries were reported frequently in the 2 to 16 year age group (3.8%).[See
Use in Specific Populations]
Clinical Trials Experience with OMEPRAZOLE in Combination Therapy for H. pylori Eradication
In clinical trials using either dual therapy with OMEPRAZOLE and clarithromycin, or triple therapy with
OMEPRAZOLE, clarithromycin, and amoxicillin, no adverse reactions unique to these drug
combinations were observed. Adverse reactions observed were limited to those previously reported with
omeprazole, clarithromycin, or amoxicillin alone.
Dual Therapy (OMEPRAZOLE/clarithromycin)
Adverse reactions observed in controlled clinical trials using combination therapy with OMEPRAZOLE
and clarithromycin (n = 346) that differed from those previously described for OMEPRAZOLE alone
were taste perversion (15%), tongue discoloration (2%), rhinitis (2%), pharyngitis (1%) and flu-syndrome
(1%). (For more information on clarithromycin, refer to the clarithromycin prescribing information,
Adverse Reactions section).
Triple Therapy (OMEPRAZOLE/clarithromycin/amoxicillin)
The most frequent adverse reactions observed in clinical trials using combination therapy with
OMEPRAZOLE, clarithromycin, and amoxicillin (n = 274) were diarrhea (14%), taste perversion (10%),
and headache (7%). None of these occurred at a higher frequency than that reported by patients taking
antimicrobial agents alone. (For more information on clarithromycin or amoxicillin, refer to the
respective prescribing information, Adverse Reactions sections).
The following adverse reactions have been identified during post-approval use of OMEPRAZOLE
Delayed-Release Capsules. Because these reactions are voluntarily reported from a population of
uncertain size, it is not always possible to reliably estimate their actual frequency or establish a causal
relationship to drug exposure.
Body As a Whole: Hypersensitivity reactions including anaphylaxis, anaphylactic shock, angioedema,
bronchospasm, interstitial nephritis, urticaria, (see also Skin below); fever; pain; fatigue; malaise;
Cardiovascular: Chest pain or angina, tachycardia, bradycardia, palpitations, elevated blood pressure,
peripheral edema

DRUG INTERACTIONS:
Interference with Antiretroviral Therapy:
Concomitant use of atazanavir and nelfinavir with proton pump inhibitors is not recommended. Co-
administration of atazanavir with proton pump inhibitors is expected to substantially decrease atazanavir
plasma concentrations and may result in a loss of therapeutic effect and the development of drug
resistance. Co-administration of saquinavir with proton pump inhibitors is expected to increase
saquinavir concentrations, which may increase toxicity and require dose reduction.
Omeprazole has been reported to interact with some antiretroviral drugs. The clinical importance and the
mechanisms behind these interactions are not always known. Increased gastric pH during omeprazole
treatment may change the absorption of the antiretroviral drug. Other possible interaction mechanisms are
via CYP 2C19.
Reduced concentrations of atazanavir and nelfinavir
For some antiretroviral drugs, such as atazanavir and nelfinavir, decreased serum levels have been
reported when given together with omeprazole. Following multiple doses of nelfinavir (1250 mg, twice
daily) and omeprazole (40 mg daily), AUC was decreased by 36% and 92%, Cmax by 37% and 89% and
Cmin by 39% and 75% respectively for nelfinavir and M8. Following multiple doses of atazanavir (400
mg, daily) and omeprazole (40 mg, daily, 2 hr before atazanavir), AUC was decreased by 94%, Cmax by
96%, and Cmin by 95%. Concomitant administration with omeprazole and drugs such as atazanavir and
nelfinavir is therefore not recommended.
Increased concentrations of saquinavir
For other antiretroviral drugs, such as saquinavir, elevated serum levels have been reported, with an
increase in AUC by 82%, in Cmax by 75%, and in Cmin by 106%, following multiple dosing of
saquinavir/ritonavir (1000/100 mg) twice daily for 15 days with omeprazole 40 mg daily co-administered
days 11 to 15. Therefore, clinical and laboratory monitoring for saquinavir toxicity is recommended
during concurrent use with PRILOSEC. Dose reduction of saquinavir should be considered from the
safety perspective for individual patients.
There are also some antiretroviral drugs of which unchanged serum levels have been reported when given
with omeprazole.
Drugs for Which Gastric pH Can Affect Bioavailability
Because of its profound and long lasting inhibition of gastric acid secretion, it is theoretically possible
that omeprazole may interfere with absorption of drugs where gastric pH is an important determinant of
their bioavailability (e.g., ketoconazole, ampicillin esters, and iron salts). In the clinical trials, antacids
were used concomitantly with the administration of PRILOSEC.
Effects on Hepatic Metabolism/Cytochrome P-450 Pathways
Omeprazole can prolong the elimination of diazepam, warfarin and phenytoin, drugs that are metabolized
by ^oxidation in the liver. There have been reports of increased INR and prothrombin time in patients
receiving proton pump inhibitors, including omeprazole, and warfarin concomitantly. Increases in INR
and prothrombin time may lead to abnormal bleeding and even death. Patients treated with proton pump
inhibitors and warfarin may need to be monitored for increases in INR and prothrombin time.
Although in normal subjects no interaction with theophylline or propranolol was found, there have been
clinical reports of interaction with other drugs metabolized via the cytochrome P450 system (e.g.,
cyclosporine, disulfiram, benzodiazepines). Patients should be monitored to determine if it is necessary to
adjust the dosage of these drugs when taken concomitantly with PRILOSEC.
Concomitant administration of omeprazole and voriconazole (a combined inhibitor of CYP2C19 and
CYP3A4) resulted in more than doubling of the omeprazole exposure. Dose adjustment of omeprazole is
not normally required. However, in patients with Zollinger-Ellison syndrome, who may require higher
doses up to 240 mg/day, dose adjustment may be considered. When voriconazole (400 mg Q12h x 1 day,
then 200 mg x 6 days) was given with omeprazole (40 mg once daily x 7 days) to healthy subjects, it
significantly increased the steady-state Cmax and AUC0-24 of omeprazole, an average of 2 times (90%
CI: 1.8, 2.6) and 4 times (90% CI: 3.3, 4.4) respectively as compared to when omeprazole was given
without voriconazole.
Omeprazole acts as an inhibitor of CYP 2C19. Omeprazole, given in doses of 40 mg daily for one week
to 20 healthy subjects in cross over study, increased Cmax and AUC of cilostazol by 18% and 26%
respectively. Cmax and AUC of one of its active metabolites, 3,4-dihydro-cilostazol, which has 4-7 times
the activity of cilostazol, were increased by 29% and 69% respectively. Co-administration of cilostazol
with omeprazole is expected to increase concentrations of cilostazol and its above mentioned active
metabolite. Therefore a dose reduction of cilostazol from 100 mg b.i.d. to 50 mg b.i.d. should be
considered.
Drugs affecting Omeprazole:
Before taking omeprazole, tell your doctor if you are taking any of the following drugs:
* a blood thinner such as warfarin (Coumadin);
* clopidogrel (Plavix);
* atazanavir (Reyataz);
* disulfiram (Antabuse);
* cyclosporine (Gengraf, Neoral, Sandimmune);
* tacrolimus (Prograf);
* phenytoin (Dilantin);
* theophylline (TheoBid, Theo-Dur, Theochron, Theolair, Elixophyllin, Slo-Phyllin);
* ketoconazole (Nizoral), voriconazole (Vfend);
* ampicillin (Omnipen, Principen);
* iron (Feosol, Mol-Iron, Fergon, Femiron, others); or
* a medicine for insomnia or anxiety such as diazepam (Valium), alprazolam (Xanax), lorazepam
(Ativan), temazepam (Restoril), clorazepate (Tranxene), chlordiazepoxide (Librium), and others.
Nonclinical Toxicology:
Carcinogenesis, Mutagenesis, Impairment of Fertility:
In two 24-month carcinogenicity studies in rats, omeprazole at daily doses of 1.7, 3.4, 13.8, 44.0 and
140.8 mg/kg/day (about 0.7 to 57 times a human dose of 20 mg/day, as expressed on a body surface area
basis) produced gastric ECL cell carcinoids in a dose-related manner in both male and female rats; the
incidence of this effect was markedly higher in female rats, which had higher blood levels of omeprazole.
Gastric carcinoids seldom occur in the untreated rat. In addition, ECL cell hyperplasia was present in all
treated groups of both sexes. In one of these studies, female rats were treated with 13.8 mg
omeprazole/kg/day (about 6 times a human dose of 20 mg/day, based on body surface area) for one year,
and then followed for an additional year without the drug. No carcinoids were seen in these rats. An
increased incidence of treatment-related ECL cell hyperplasia was observed at the end of one year (94%
treated vs 10% controls). By the second year the difference between treated and control rats was much
smaller (46% vs 26%) but still showed more hyperplasia in the treated group. Gastric adenocarcinoma
was seen in one rat (2%). No similar tumor was seen in male or female rats treated for two years. For this
strain of rat no similar tumor has been noted historically, but a finding involving only one tumor is
difficult to interpret. In a 52-week toxicity study in Sprague-Dawley rats, brain astrocytomas were found
in a small number of males that received omeprazole at dose levels of 0.4, 2, and 16 mg/kg/day (about
0.2 to 6.5 times the human dose on a body surface area basis). No astrocytomas were observed in female
rats in this study. In a 2-year carcinogenicity study in Sprague-Dawley rats, no astrocytomas were found
in males or females at the high dose of 140.8 mg/kg/day (about 57 times the human dose on a body
surface area basis). A 78-week mouse carcinogenicity study of omeprazole did not show increased tumor
occurrence, but the study was not conclusive. A 26-week p53 (+/-) transgenic mouse carcinogenicity
study was not positive.
Omeprazole was positive for clastogenic effects in an in vitro human lymphocyte chromosomal
aberration assay, in one of two in vivo mouse micronucleus tests, and in an in vivo bone marrow cell
chromosomal aberration assay. Omeprazole was negative in the in vitro Ames test, an in vitro mouse
lymphoma cell forward mutation assay, and an in vivo rat liver DNA damage assay.
Omeprazole at oral doses up to 138 mg/kg/day in rats (about 56 times the human dose on a body surface
area basis) was found to have no effect on fertility and reproductive performance.
OVERDOSE:
Reports have been received of overdosage with omeprazole in humans. Doses ranged up to 2400 mg (120
times the usual recommended clinical dose). Manifestations were variable, but included confusion,
drowsiness, blurred vision, tachycardia, nausea, vomiting, diaphoresis, flushing, headache, dry mouth,
and other adverse reactions similar to those seen in normal clinical experience.
Symptoms were transient, and no serious clinical outcome has been reported when PRILOSEC was taken
alone. No specific antidote for omeprazole overdosage is known. Omeprazole is extensively protein
bound and is, therefore, not readily dialyzable. In the event of overdosage, treatment should be
symptomatic and supportive.
Single oral doses of omeprazole at 1350, 1339, and 1200 mg/kg were lethal to mice, rats, and dogs,
respectively. Animals given these doses showed sedation, ptosis, tremors, convulsions, and decreased
activity, body temperature, and respiratory rate and increased depth of respiration.
MISSED DOSE:
If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed
dose and resume your usual dosing schedule. Do not double the dose to catch up.
CONTRAINDICATIONS:
OMEPRAZOLE Delayed-Release Capsules are contraindicated in patients with known hypersensitivity
to substituted benzimidazoles or to any component of the formulation. Hypersensitivity reactions may
include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, interstitial nephritis, and urticaria
STORAGE:
Store at room temperature between 59-86 degrees F (15-30 degrees C) away from light and moisture. Do
not store in the bathroom. Keep all medicines away from children and pets.
Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly
discard this product when it is expired or no longer needed.
