30
-zosin
alpha blockers
31
Combinations to avoid
- ACE inhibitors, ARBs, and renin inhibitors - Beta blockers and non dihydropyrine - Potassium sparing diuretics and ACE inhibitors
32
Most effective parenteral drug for hypertensive emergencies
Sodium nitroprusside- vasodilator Potential for cyanide toxicity limits prolonged use
33
Less antihypertensive efficacy than other agents for HTN emergencies; useful adjunct in pts with cardiac ischemia or after coronary bypass surgery
Nitroglycerin-vasodilator
34
DHP-CCB with longer onset of action and longer elimination half life, but good safey profile
Nicardipine-vasodilator
35
Ultra short-acting DHP-CCB is approved only for hypertensive emergencies
Clevidipine-vasodilator
36
Rarely used due to slow onset and long duration of action; hypotensive response is unpredictable and dependent on plasma volume and plasma renin activity
Enalaprilat-vasodilator
37
Maintains or increases renal perfusion by dilating renal arteries; possibly a good choice for patients with renal dysfunction; avoid in glaucoma
Fenoldopam-vasodilator
38
Use of parenteral form limited by prolonged and unpredictable hypotensive effect; considered safe in pregnant patients
hydralazine-vasodilator
39
Acute management of severe hypertension in pregnancy
1. Labetalol 2. Hydralazine- only used if preeclampsia 3. CCB- nifedipine or nicardipine 4. Nitroglycerin- good when HTN is associated w pulmonary edema
40
Long term oral therapy for HTN in pregnancy
1. Methyldopa 2. Labetalol 3. Nifedipine 4. Hydralazine 5. Thiazide
