increased blood pressure (severe headache, blurred vision); seizure (convulsions); feeling light-headed, fainting; pounding heartbeat; chest pain or heavy feeling, pain spreading to the arm or shoulder,...

Read All Potential Side Effects and See Pictures of Methergine »

Methergine® (methylergonovine maleate) is a semi-synthetic ergot alkaloid used for the prevention and control ofpostpartum hemorrhage.

INDICATIONSFor routine management after delivery of the placenta; postpartum atony andhemorrhage; subinvolution. Under full obstetric supervision, it may be given in thesecond stage of labor following delivery of the anterior shoulder.

DOSAGE AND ADMINISTRATIONParenteral drug products should be inspected visually for particulate matter and discoloration prior to administration.

Intramuscularly

1 mL, 0.2 mg, after delivery of the anterior shoulder, after delivery of the placenta, or during the puerperium. May be repeated as required, at intervals of 2-4 hours.

Intravenously

Dosage same as intramuscular. (See WARNINGS.)

Orally

One tablet, 0.2 mg, 3 or 4 times daily in the puerperium for a maximum of 1 week.

SIDE EFFECTSThe most common adverse reaction is hypertension associated in several cases with seizure and/or headache. Hypotension has also been reported. Nausea and vomiting have occurred occasionally. Rarely observed reactions have included:acute myocardial infarction, transient chest pains, arterial spasm (coronary and peripheral), bradycardia, tachycardia, dyspnea, hematuria, thrombophlebitis, water intoxication, hallucinations, leg cramps, dizziness, tinnitus, nasal congestion, diarrhea, diaphoresis, palpitation, rash, and foul taste.1

There have been rare isolated reports of anaphylaxis, without a proven causal relationship to the drug product.

Drug Abuse And Dependence

Methergine® (methylergonovine maleate) has not been associated with drug abuse or dependence of either a physical or psychological nature.

WARNINGSThis drug should not be administered I.V. routinely because of the possibility of inducing sudden hypertensive and cerebrovascular accidents. If I.V. administration is considered essential as a lifesaving measure, Methergine® (methylergonovine maleate) should be given slowly over a period of no less than 60 seconds with careful monitoring of blood pressure. Intra-arterial or periarterial injection should be strictly avoided.

PRECAUTIONS

General

Caution should be exercised in the presence of sepsis, obliterative vasculardisease, hepatic or renal involvement. Also use with caution during the second stage of labor. The necessity for manual removal of a retained placenta should occur only rarely with proper technique and adequate allowance of time for its spontaneous separation.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No long-term studies have been performed in animals to evaluate carcinogenicpotential. The effect of the drug on mutagenesis or fertility has not been determined.

Pregnancy

Category C. Animal reproductive studies have not been conducted with Methergine. It is also not known whether methylergonovine maleate can cause fetal harm or can affect reproductive capacity. Use of Methergine is contraindicated during pregnancy because of its uterotonic effects. (SeeINDICATIONS AND USAGE.)

Labor and Delivery

The uterotonic effect of Methergine is utilized after delivery to assist involution and decrease hemorrhage, shortening the third stage of labor.

Nursing Mothers

Methergine® (methylergonovine maleate) may be administered orally for a maximum of 1 week postpartum to control uterine bleeding. Recommended dosage is 1 tablet (0.2 mg) 3 or 4 times daily. At this dosage level a small quantity of drug appears in mothers' milk. Caution should be exercised when Methergine is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Clinical studies of Methergine did not include sufficient number of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger patients. In general dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

OVERDOSESymptoms of acute overdose may include: nausea, vomiting, abdominal pain, numbness, tingling of the extremities, rise in blood pressure, in severe cases followed by hypotension, respiratory depression, hypothermia, convulsions, andcoma.

Because reports of overdosage with Methergine® (methylergonovine maleate) are infrequent, the lethal dose in humans has not been established. The oral LD50 (in mg/kg) for the mouse is 187, the rat 93, and the rabbit 4.5.2 Several cases of accidental Methergine injection in newborn infants have been reported, and in such cases 0.2 mg represents an overdose of great magnitude. However, recovery occurred in all but one case following a period of respiratory depression, hypothermia, hypertonicity with jerking movements, and, in one case, a single convulsion.

Also, several children 1-3 years of age have accidentally ingested up to 10 tablets (2 mg) with no apparent ill effects. A postpartum patient took 4 tablets at one time in error and reported paresthesias and clamminess as her only symptoms.

Treatment of acute overdosage is symptomatic and includes the usual procedures of:

1. removal of offending drug by inducing emesis, gastric lavage, catharsis, and supportive diuresis.2. maintenance of adequate pulmonary ventilation, especially if convulsions or coma develop.3. correction of hypotension with pressor drugs as needed.4. control of convulsions with standard anticonvulsant agents.5. control of peripheral vasospasm with warmth to the extremities if needed.3

CONTRAINDICATIONSHypertension; toxemia; pregnancy; and hypersensitivity.

Department.

CLINICAL PHARMACOLOGYMethergine® (methylergonovine maleate) acts directly on the smooth muscle of the uterus and increases the tone, rate, and amplitude of rhythmic contractions. Thus, it induces a rapid and

sustained tetanic uterotonic effect which shortens the third stage of labor and reduces blood loss. The onset of action after I.V. administration is immediate; after I.M. administration, 2-5 minutes, and after oral administration, 5-10 minutes.

Pharmacokinetic studies following an I.V. injection have shown that methylergonovine is rapidly distributed from plasma to peripheral tissues within 2-3 minutes or less. The bioavailability after oral administration was reported to be about 60% with no accumulation after repeated doses. During delivery, withintramuscular injection, bioavailability increased to 78%. Ergot alkaloids are mostly eliminated by hepatic metabolism and excretion, and the decrease in bioavailability following oral administration is probably a result of first-pass metabolism in the liver.

Bioavailability studies conducted in fasting healthy female volunteers have shown that oral absorption of a 0.2 mg methylergonovine tablet was fairly rapid with a mean peak plasma concentration of 3243 ± 1308 pg/mL observed at 1.12 ± 0.82 hours. For a 0.2 mg intramuscular injection, a mean peak plasma concentration of 5918 ± 1952 pg/mL was observed at 0.41 ± 0.21 hours. The extent of absorption of the tablet, based upon methylergonovine plasma concentrations, was found to be equivalent to that of the I.M. solution given orally, and the extent of oral absorption of the I.M. solution was proportional to the dose following administration of 0.1, 0.2, and 0.4 mg. When given intramuscularly, the extent of absorption of Methergine solution was about 25% greater than the tablet. The volume of distribution (Vdss/F) of methylergonovine was calculated to be 56.1 ± 17.0 liters, and the plasma clearance (CLp/F) was calculated to be 14.4 ± 4.5 liters per hour. The plasma level decline was biphasic with a mean elimination half-life of 3.39 hours (range 1.5 to 12.7 hours). A delayed gastrointestinalabsorption (Tmax about 3 hours) of Methergine tablet might be observed inpostpartum women during continuous treatment with this oxytocic agent.

USES:This medication is used after childbirth to help stop bleeding from the uterus. Methylergonovine belongs to a class of drugs known as ergot alkaloids. It works by increasing the rate and strength of contractions and the stiffness of the uterus muscles. These effects help to decrease bleeding.HOW TO USE:Take this medication by mouth with or without food, usually 3 to 4 times daily for up to 1 week after delivery or as directed by your doctor.Dosage is based on your medical condition and response to treatment.

VITAMIN K1INJECTIONPhytonadioneInjectable Emulsion, USP

Phytonadione is a vitamin, which is a clear, yellow to amber, viscous, odorless or nearly odorless liquid. It is insoluble in water, soluble in chloroform and slightly soluble in ethanol.

Vitamin K1 Injection (Phytonadione Injectable Emulsion, USP) is indicated in the following coagulation disorders which are due to faulty formation of factors II, VII, IX and X when caused by vitamin K deficiency or interference with vitamin K activity.

Vitamin K1 Injection is indicated in:

anticoagulant-induced prothrombin deficiency caused by coumarin or indanedione derivatives;

prophylaxis and therapy of hemorrhagic disease of the newborn; hypoprothrombinemia due to antibacterial therapy; hypoprothrombinemia secondary to factors limiting absorption or synthesis of vitamin K, e.g.,

obstructive jaundice, biliary fistula, sprue, ulcerative colitis, celiac disease, intestinal resection, cystic fibrosis of the pancreas, and regional enteritis;

other drug-induced hypoprothrombinemia where it is definitely shown that the result is due to interference with vitamin K metabolism, e.g., salicylates.

DOSAGE AND ADMINISTRATION

Whenever possible, Vitamin K1 Injection (Phytonadione Injectable Emulsion, USP) should be given by the subcutaneous route. (See Box Warning.) When intravenous administration is considered unavoidable, the drug should be injected very slowly, not exceeding 1 mg per minute.

Protect from light at all times.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Directions for Dilution

Vitamin K1 Injection may be diluted with 0.9% Sodium Chloride Injection, 5% Dextrose Injection, or 5% Dextrose and Sodium Chloride Injection. Benzyl alcohol as a preservative has been associated with toxicity in newborns. Therefore,all of the above diluents should be preservative-free (see WARNINGS). Other diluents should not be used. When dilutions are indicated, administration should be started immediately after mixture with the diluent, and unused portions of the dilution should be discarded, as well as unused contents of the ampul.

Prophylaxis of Hemorrhagic Disease of the Newborn

The American Academy of Pediatrics recommends that vitamin K1 be given to the newborn. A single intramuscular dose of Vitamin K1 Injection 0.5 to 1 mg within one hour of birth is recommended.

Treatment of Hemorrhagic Disease of the Newborn

Empiric administration of vitamin K1 should not replace proper laboratory evaluation of the coagulation mechanism. A prompt response (shortening of the prothrombin time in 2 to 4 hours) following administration of vitamin K1 is usually diagnostic of hemorrhagic disease of the newborn, and failure to respond indicates another diagnosis or coagulation disorder.

Vitamin K1 Injection 1 mg should be given either subcutaneously or intramuscularly. Higher doses may be necessary if the mother has been receiving oral anticoagulants.

Whole blood or component therapy may be indicated if bleeding is excessive. This therapy, however, does not correct the underlying disorder and Vitamin K1 Injection should be given concurrently.

Effective for:

Treating and preventing vitamin K deficiency.

Preventing certain bleeding or blood clotting problems.

Reversing the effects of too much warfarin used to prevent blood clotting.

Vitamin K is safe for most people. Most people do not experience any side effects when taking in the recommended amount each day.

Special Precautions & Warnings:

Pregnancy  and breast-feeding: When taken in the recommended amount each day, vitamin K is considered safe for pregnant and breast-feeding women, but don't use higher amounts without the advice of your healthcare professional.

Kidney disease: Too much vitamin K can be harmful if you are receiving dialysis treatments due to kidney disease.

Liver disease: Vitamin K is not effective for treating clotting problems caused by severe liver disease. In fact, high doses of vitamin K can make clotting problems worse in these people.

MEPHYTON is indicated in the following coagulation disorders which are due to faulty formation of factors II, VII, IX and X when caused by vitamin K deficiency or interference with vitamin K activity.

MEPHYTON tablets are indicated in:

— anticoagulant-induced prothrombin deficiency caused by coumarin or indanedione derivatives;

— hypoprothrombinemia secondary to antibacterial therapy;

— hypoprothrombinemia secondary to administration of salicylates;

— hypoprothrombinemia secondary to obstructive jaundice or biliary fistulas but only if bile salts are administered concurrently, since otherwise the oral vitamin K will not be absorbed

SIDE EFFECTSSevere hypersensitivity reactions, including anaphylactoid reactions and deaths have been reported following parenteral administration. The majority of these reported events occurred following intravenous administration.

Transient "flushing sensations" and "peculiar" sensations of taste have been observed with parenteral phytonadione, as well as rare instances of dizziness, rapid and weak pulse, profuse sweating, brief hypotension, dyspnea, andcyanosis.

Hyperbilirubinemia has been observed in the newborn following administration of parenteral phytonadione. This has occurred rarely and primarily with doses above those recommended.

WARNINGSAn immediate coagulant effect should not be expected after administration of phytonadione.

Phytonadione will not counteract the anticoagulant action of heparin.

When vitamin K1 is used to correct excessive anticoagulant-induced hypoprothrombinemia, anticoagulant therapy still being indicated, the patient is again faced with the clotting hazards existing prior to starting the anticoagulant therapy. Phytonadione is not a clotting agent, but overzealous therapy with vitamin K1 may restore conditions which originally permitted thromboembolic phenomena. Dosage should be kept as low as possible, and prothrombin timeshould be checked regularly as clinical conditions indicate.

Repeated large doses of vitamin K are not warranted in liver disease if the response to initial use of the vitamin is unsatisfactory. Failure to respond to vitamin K may indicate a congenital coagulation defect or that the condition being treated is unresponsive to vitamin K.

PRECAUTIONS

General

Vitamin K1 is fairly rapidly degraded by light; therefore, always protect MEPHYTON from light. Store MEPHYTON in closed original carton until contents have been used. (See also HOW SUPPLIED, Storage.)

Carcinogenesis, Mutagenesis, Impairment of Fertility

Studies of carcinogenicity or impairment of fertility have not been performed with MEPHYTON. MEPHYTON at concentrations up to 2000 mcg/plate with or without metabolic activation, was negative in the Ames microbial mutagen test.

Pregnancy

Pregnancy Category C: Animal reproduction studies have not been conducted with MEPHYTON. It is also not known whether MEPHYTON can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. MEPHYTON should be given to a pregnant woman only if clearly needed.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established with MEPHYTON. Hemolysis, jaundice, and hyperbilirubinemia in newborns, particularly in premature infants, have been reported with vitamin K.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when MEPHYTON is administered to a nursing woman.

Geriatric Use

Clinical studies of MEPHYTON did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

OVERDOSEThe intravenous and oral LD50s in the mouse are approximately 1.17 g/kg and greater than 24.18 g/kg, respectively.

CONTRAINDICATIONSHypersensitivity to any component of this medication.

CLINICAL PHARMACOLOGYMEPHYTON tablets possess the same type and degree of activity as does naturally-occurring vitamin K, which is necessary for the production via the liverof active prothrombin (factor II), proconvertin (factor VII), plasma thromboplastin component (factor IX), and Stuart factor (factor X). The prothrombin test is sensitive to the levels of three of these four factors – II, VII, and X. Vitamin K is

an essential cofactor for a microsomal enzyme that catalyzes the posttranslational carboxylation of multiple, specific, peptidebound glutamic acidresidues in inactive hepatic precursors of factors II, VII, IX, and X. The resulting gammacarboxyglutamic acid residues convert the precursors into activecoagulation factors that are subsequently secreted by liver cells into the blood.

Oral phytonadione is adequately absorbed from the gastrointestinal tract only ifbile salts are present. After absorption, phytonadione is initially concentrated in the liver, but the concentration declines rapidly. Very little vitamin K accumulates in tissues. Little is known about the metabolic fate of vitamin K. Almost no free unmetabolized vitamin K appears in bile or urine.

In normal animals and humans, phytonadione is virtually devoid of pharmacodynamic activity. However, in animals and humans deficient in vitamin K, the pharmacological action of vitamin K is related to its normal physiological function; that is, to promote the hepatic biosynthesis of vitamin K-dependent clotting factors.

MEPHYTON tablets generally exert their effect within 6 to 10 hours.

USES:Vitamin K is used to treat and prevent low levels of certain substances (blood clotting factors) that your body naturally produces. These substances help your blood to thicken and stop bleeding normally (e.g., after an accidental cut or injury). Low levels of blood clotting factors increase the risk for unusual bleeding. Low levels may be caused by certain medications (e.g., warfarin) or medical conditions (e.g., obstructive jaundice). Vitamin K helps to treat and prevent unusual bleeding by increasing the body's production of blood clotting factors.HOW TO USE:Take this medication by mouth exactly as directed by your doctor. Dosage is based on your medical condition and response to treatment.If you are using a certain "blood thinner" drug (warfarin), vitamin K can decrease the effects of warfarin for up to 2 weeks. Therefore, be sure to take your vitamin K and warfarin exactly as directed by your doctor or pharmacist.

If you develop easy bruising or bleeding, seek immediate medical attention. You may need another dose of vitamin K.

SIDE EFFECTS:Vitamin K usually has very few side effects. If you have any unusual effects from taking this medicine, tell your doctor or pharmacist promptly.If your doctor has prescribed this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

PRECAUTIONS:Before taking vitamin K, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies.Before using this medication, tell your doctor or pharmacist your medical history, especially of: blood disorders, gallbladder disease (e.g., obstructive jaundice, biliary fistula), liver disease.

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

It is not known whether this medication passes into breast milk. Consult your doctor before breast-feeding.

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. Consult your pharmacist or local waste disposal company for more details about how to safely discard your product.

Dosage Usual Recommended Dose: Adults: 0.15-0.2 mg/kg body weight. Children: 0.1-0.2 mg/kg up to a total single dose of 10 mg.

Nubain may be administered SC, IM or IV. The doses may be repeated every 3-6 hrs or as needed. Dosage should be adjusted according to severity of pain and physical status of the patient.

Overdosage Symptoms: The administration of single IM doses of 72 mg of nalbuphine HCl to 8 normal subjects has been reported to have resulted primarily in symptoms of sleepiness and mild dysphoria.

Treatment: Naloxone HCl is a specific antidote for nalbuphine HCl, but symptomatic and supportive therapy will usually suffice for mild or moderate overdosage. Oxygen, IV fluids, vasopressors and other supportive measures should be employed as indicated.

Contraindications Patients who are hypersensitive to nalbuphine HCl.

Warnings Drug Dependence: Nalbuphine HCl cannot be substituted for heroine, methadone or other narcotics in physically dependent individuals. It will precipitate abstinence in such patients. Nalbuphine HCl has been shown to have a low abuse potential. Psychological and physical dependence

and tolerance may follow the misuse or abuse of nalbuphine; therefore, caution should be observed in prescribing it for emotionally unstable patients or for individuals with a history of narcotic abuse. When nalbuphine HCl is selected for the control of chronic pain, care should be taken to avoid increases in dosage or the frequency of administration which, in susceptible individuals, might result in physical dependence and tolerance. Abrupt withdrawal after chronic use can precipitate abstinence syndrome.

Use in Ambulatory Patients: Nalbuphine HCl may impair the mental or physical abilities required for the performance of potentially dangerous tasks eg, driving a car or operating machinery. Therefore, it should be administered with caution to ambulatory patients who should be warned to avoid such hazards.

Use in Pregnancy: Safe use of nalbuphine HCl in pregnancy (other than labor) has not been established. It should only be administered to pregnant women (other than in labor) when, in the judgement of the physician, the potential benefits outweigh the possible hazards. Potent analgesics should be used with caution in women delivering premature infants. In full-term labor, 10-15 mg of nalbuphine has provided analgesia equivalent to that of 75-113 mg of meperidine with fewer maternal side effects.

Use During Labor and Delivery: The placental transfer of nalbuphine is high, rapid and variable with a maternal-to-fetal ratio ranging from 1:0.37 to 1:1.6. Fetal and neonatal adverse effects that have been reported following the administration of nalbuphine to the mother during labor include fetal tachycardia, respiratory depression at birth, apnea and cyanosis. Maternal administration of naloxone during labor has normalized these effects in some cases. Severe and prolonged fetal bradycardia has been reported. Permanent neurological damage attributed to fetal bradycardia has occurred. A sinusoidal fetal heart rate pattern associated with the use of nalbuphine has also been reported. Nubain should be used with caution in women during labor and delivery, and newborns should be monitored for respiratory depression, apnea, bradycardia and arrhythmias if Nubain has been used.

Head Injury and Increased Intracranial Pressure: The possible respiratory depressant effects and the potential of potent analgesics to elevate cerebrospinal fluid pressure (resulting from vasodilation following CO2 retention) may be

markedly exaggerated in the presence of head injury, intracranial lesions or a preexisting increase in intracranial pressure. Furthermore, potent analgesics can produce effects which may obscure the clinical course of patients with head injuries. Therefore, nalbuphine HCl should be used in these circumstances only when essential, and then should be administered with extreme caution.

Special Precautions Impaired Respiration: 10 mg of nalbuphine HCl causes some respiratory depression approximately equivalent to 10 mg of morphine. However, in contrast to morphine, respiratory depression is not appreciably increased with higher doses of nalbuphine HCl. Respiratory depression induced by nalbuphine HCl can be reversed by naloxone HCl when indicated. It should be administered with caution at low doses to patients with impaired respiration (eg, from other medication, uremia, bronchial asthma, severe infection, cyanosis or respiratory obstruction).

Impaired Renal or Hepatic Function: Because nalbuphine HCl is metabolized in the liver and excreted by the kidneys, patients with renal or liver dysfunction may over-react to customary doses. Therefore, in these individuals, nalbuphine HCl should be used with caution and administered in reduced amounts. However, liver and renal function tests on patients who have received nalbuphine HCl in single and chronic dosages do not reveal any changes attributable to its administration.

Use in pregnancy & lactation: Caution should be exercised when administered to pregnant and nursing patients. Nalbuphine should only be administered when in the judgement of the physician, the potential benefits outweigh the possible hazards (see Warnings).

Adverse Drug Reactions

The most commonly occurring reactions are sedation, drowsiness, sweating, nausea, dry mouth and dizziness. Pain at injection site, headache, vomiting and lightheadedness occur less frequently. Restlessness, blurred vision, chills, euphoria and impaired respiration have been infrequent.

Nubain produces few if any psychotomimetic side effects eg, visual hallucinations and dysphoria.

Monitoring on the Usage: Prescriptions of Nubain shall be through an ordinary prescription form wherein the name, address, S2 license number and PTR number of the prescribing practitioner shall be stated, as well as the name, address and age of the patient. The pharmacist must

keep a record of its sales including the name and address of the prescribing physician in an Additional Dangerous Drugs Record Book registered prior to use.Click to view ADR Monitoring Website

Drug Interactions With Other Central Nervous System Depressants: Although nalbuphine HCl possesses narcotic antagonistic activity, there is evidence that in non-dependent patients, it will not antagonize a narcotic analgesic administered just before, concurrently, or just after an injection of nalbuphine HCl. Therefore, patients receiving narcotic analgesics, general anesthetics, phenothiazines or other tranquilizers, sedatives, hypnotics or other CNS depressants (including alcohol) concomitantly with nalbuphine HCl may exhibit an additive effect. When such combined therapy is contemplated, the dose of one or both agents should be reduced.View more drug interactions for   Nubain

Pregnancy Category (US FDA)

Category B: Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1sttrimester (and there is no evidence of a risk in later trimesters).

if prolonged use/high doses at term.

Category D: There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).

Storage Store at temperatures not exceeding 30°C.

Description Each mL of Nubain ampoule also contains sodium chloride 2 mg, sodium citrate 9.41 mg and anhydrous citric acid 12.62 mg; pH is adjusted with hydrochloric acid.

Nalbuphine HCl is (-)-17-(cyclobutylmethyl)-4,5α-epoxymorphinan-3,6α,14-triol hydrochloride. It is a synthetic agonist-antagonist analgesic of the phenanthrene series which is chemically related to both the widely used narcotic antagonist, naloxone, and the potent analgesic, oxymorphone.

Mechanism of Action Pharmacology: Nalbuphine HCl is a potent analgesic, 10 mg of which is comparable in analgesic potency to 8-10 mg of morphine sulfate, whether administered IV, SC or IM.

The onset of action occurs within 2-3 min after IV administration of nalbuphine HCl and in <10 min following SC or IM injection.

Clinical experience suggests that in some patients, analgesia may be longer lasting than from comparable doses of morphine, effects having been observed in acute and chronic pain for 3-8 hrs. The t½ of nalbuphine is 5 hrs.

Nalbuphine HCl has the effect of lowering the cardiac work load and can be used immediately in myocardial infarction (use with caution where emesis is involved). Hemodynamic studies in patients with severe arteriosclerotic heart changes reveal that nalbuphine HCl has circulatory effects similar to those of morphine ie, a minimal decrease in oxygen consumption, cardiac index, left ventricular end diastolic pressure and cardiac work.

Nalbuphine HCl antagonist activity is ¼ as potent as nalorphine and approximately 1/40 that of naloxone.
