DRUG THERAPY OF HYPERTENSION 1) CALCIUM CHANNEL BLOCKERS (CCBs) Exаmples: DHP: Amlоdipine, Nifedipine, Nicаrdipine Nоn-DHP: Verаpamil, Diltiazem MOA Blоck L-type Ca²⁺ channels → ↓ vascular tone + ↓ cardiac activity (non-DHP) Effects Vasodilation → ↓ afterload ↓ myocardial O₂ demand ↑ coronary perfusion Uses HTN (first-line option) Pregnancy HTN (safe) Angina SVT (non-DHP) PAD AEs DHP: Edema Flushing Reflex tachycardia Non-DHP: Bradycardia AV block Worsening HF Gingival hyperplasia Constipation (verapamil) 2) DIRECT VASODILATORS 1. Hydralazine Arteriolar vasodilator Uses: pregnancy HTN, HF (with nitrates) AE: drug-induced lupus, tachycardia 2. Minoxidil K⁺ channel opener → arteriolar dilation AE: hypertrichosis, pericardial effusion 3. Sodium Nitroprusside Sodium nitroprusside NO donor → balanced arterial + venous dilation Use: hypertensive emergency (ICU only) AE: cyanide toxicity (life-threatening) 3) SYMPATHOLYTICS 1. Central α2 agonists: Clonidine, Methyldopa MOA ↓ sympathetic outflow → ↓ HR, CO, renin Uses Resistant HTN Methyldopa = drug of choice in pregnancy AEs Sedation, dry mouth Rebound HTN (clonidine withdrawal) Hemolytic anemia (methyldopa) 2. α-Blockers α1 blockers: Prazosin MOA: vasodilation → ↓ BP Uses: HTN + BPH AE: first-dose orthostatic hypotension α1 + α2 blockers: Phentolamine (pheochromocytoma emergency) Uses: Pheochromocytoma crisis Catecholamine extravasation AE: reflex tachycardia 3. β-Blockers: Metoprolol, Propranolol, Carvedilol, Labetalol MOA ↓ renin (kidney) ↓ HR + contractility → ↓ CO Uses Post-MI HFrEF (selected agents) HTN with tachycardia Pregnancy HTN (labetalol) Pheochromocytoma (with α-blockade) AEs Bradycardia, AV block Bronchospasm (non-selective) Mask hypoglycemia Sexual dysfunction CNS effects (fatigue, depression) Rebound HTN if stopped abruptly Question: A 55-year-old patient is treated for hypertensive emergency in the ICU with a continuous IV medication.
