Definition: Hypertension
A medical condition in which the pressure in the arteries are elevated.
Hypertension is considered after the BP reaches 140/90 mm Hg or higher or when pt is on antihypertensive drug therapy.
Blood pressure is measured in two ways: Systolic Diastolic
![Page 12: Hypertension Case Presentation](https://reader036.fdocuments.in/reader036/viewer/2022062501/56816583550346895dd826b9/html5/thumbnails/12.jpg)
Diagnosis
Periodic screening for all individuals older than 21 years
Patient seated quietly in chair for at least 5 minutes
Use appropriate cuff size (bladder length at least 80% the circumference of the arm).
Take BP at least 2 times, separated by at least 2 minutes.
The average BP on two separate visits is required to diagnose hypertension accurately.

$28-$40
Calcium Channel Blockers
Non-Dihydropyridines:Inhibits calcium ion from entering the “slow channels” or select voltage-sensitive areas of vascular smooth muscle and myocardium
Diltiazem (Cardizem®)Verapamil (Calan®)

Classes of Anti-Hypertensives
Class Mechanism of Action
Examples Cost
Angiotensin Converting Enzyme Inhibitors (ACE Inhibitors)
Inhibits the activity of the enzyme ACE, which decreases the production of angiotensin II. As a result, the blood vessels enlarge or dilate, and blood pressure is reduced.
Prinivil (Lisinopril®) Benazepril (Lotensin®)Enalapril (Vasotec®)
$30-$90
Angiotensin Receptor Blockers (ARBs)
Blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II
Olmesartan (Benicar®) Valsartan (Diovan®)Losartan (Cozaar®)
$50-$80

Hydralazine (Apresoline®)Clonidine (Catapres®)Methyldopa (Aldomet®)
$15-$29
Nitrates Improves the contractile state in smooth muscle by stimulating guanylate cyclase through formation of free radical nitric oxide thus causing vasodilation.
Nitrogylcerin (Nitrostat®)
$25-35

Furosemide (Lasix®)Torsemide (Demadex®)Bumetanide (Bumex®)
$10-$30
Thiazide Diuretics:Decrease active re-absorption of sodium and chloride ions by inhibiting the sodium/chloride co-transporter in the distal convoluted tubule
Hydrochlorothiazide (Microzide®)Methylclothiazide (Enduron®)
$10-$30
![Page 20: Hypertension Case Presentation](https://reader036.fdocuments.in/reader036/viewer/2022062501/56816583550346895dd826b9/html5/thumbnails/20.jpg)
Classes of Anti-Hypertensives
Class Mechanism of Action
Examples Cost
Diuretics
Thiazide-Like Diuretics:Sulfonamide-derived diuretic that inhibits sodium and chloride reabsorption in the cortical-diluting segment of the ascending loop of Henle
Chlorthalidone (Thalitone®)Indapamide (Lozol®)
$10-$35
Osmotic Diuretics:Promotes diuresis by increasing osmolarity and therefore blocking the tubular reabsorption of water
Mannitol(Osmitrol®)
$7-$32

No therapy for hypertension and hyperlipidemia in place
Appropriate Drug Selection Glipizide alone not effective for NIDDM
