Study Notes
Antihypertensive Medications Overview
- ACE inhibitors include lisinopril, benazepril, enalapril, ramipril, and captopril; they block the conversion of angiotensin I to II and are indicated for hypertension, post-MI, and diabetic nephropathy
- ACE inhibitors have side effects such as hyperkalemia, angioedema, and cough, and are contraindicated in pregnancy, renal artery stenosis, and concurrent use with spironolactone or lithium
- ARBs, like valsartan and losartan, competitively inhibit angiotensin II and are indicated for hypertension, heart failure, and diabetic nephropathy/retinopathy
- ARBs have similar side effects to ACE inhibitors and are contraindicated in pregnancy and renal artery stenosis
- Calcium channel blockers (CCBs) such as amlodipine, nicardipine, and nifedipine block calcium channels on peripheral smooth muscle and are indicated for hypertension, dysrhythmias, and angina
- Renin inhibitors like aliskiren decrease plasma renin activity and are indicated for hypertension, often combined with CCBs or HCTZ
- Alpha-1 antagonists (blockers) like doxazosin and prazosin block vascular alpha-1 receptors on smooth muscle and are indicated for hypertension, with off-label uses including BPH and PTSD nightmares
- Alpha-2 agonists like clonidine and methyldopa reduce sympathetic outflow and are indicated for hypertension, with off-label uses including pain, opioid withdrawal, and ADHD
- Beta blockers have first, second, and third-generation types, with varying indications and contraindications based on their selectivity and effects on the lungs and heart
- Vasodilators like hydralazine and sodium nitroprusside are indicated for hypertension and heart failure, with specific considerations for monitoring and contraindications
- Nitrates like nitroglycerin act directly on the smooth muscle of arterioles via nitric oxide and are indicated for angina, with contraindications for glaucoma, migraines, and certain medical conditions
- Medications to avoid in pregnancy include ACE/ARB/RI, propranolol, atenolol, metoprolol, and bisoprolol, with labetalol and methyldopa being first-line treatments for pregnancy-induced hypertension. Nifedipine and HCTZ are second-line treatments.
