Question | Answer |
---|---|
Adrenergic Drugs - Central Acting - a2 receptor agonists | clonidine (Catapres),guanfacine (Tenex), methyldopa (Aldomet) |
Adrenergic Drugs - Peripheral a1 blockers/antagonists | end in -zosin doxazosin (Cardura), prazosin (Minipress), erazosin (Htrin), |
Adrenergic Drugs - b blockers | Propranolol, atenolol, othersReduce BP by reducing HRreduced secretion of reninLT use causes reduced peripheral vascular resistance |
Adrenergic Drugs - Dual Action a1 & b recepetor blockers | labetalol (Normodyne) and carvedilol (Coreg)Reduce HR (b1 receptor blockade) Vasodilation (a1 receptor blockade) |
ACE Inhibitors - Angiotensin Converting Enzyme Inhibitors | end in -pril captopril (Capoten), enalapril (Vasotec), lisinopril (Prinivil and Zestril) & quinapril (Accupril) and others |
ACE Inhibitors - Adverse Effects | Fatigue, HA, Dry non-productive cough, Dizziness, 1st dose hypotensive effect may occur - falls |
Angiotensin II Receptor Blockers | end in -sartanlosartan(Cozar, Hyzaar), valsartan (Diovan), eposartan, irbesartan |
Calcium Channel Blockers | Prevents smooth muscle contraction result decreased BP - Benzothiazepines - diltiazem (Cardizem, Dilacor), Phenylalkamines - verapamil (Calan, Isoptin), Dihydropyridines - amlodipine (Norvasc), bepridil (Vascor), nicardipine (Cardene), nifedipine (Procard |
Diuretics | thiazide diuretics most commonly used for hypotension |
Vasodilators | diazoxide (Hyperstat), hydralazine HCl (Apresoline), minoxidil (Loniten), sodium nitroprusside (Nipride, Nitropress) *IV Med for malignant HTN, Emergency use, photo sensative |
Nursing Implications | Never double up, Monitor BP, keep journal of regular BP checks, should not be stopped abruptly - rebound hypertension - lead to stroke, change positions slowly, decreased sex drive, avoid ETOH, hot tubs and baths, hot weather, BP kept < 130/90 |
