AZOR vs SERPASIL-APRESOLINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amlodipine is a dihydropyridine calcium channel blocker that inhibits calcium ion influx across cardiac and vascular smooth muscle cells, causing vasodilation and reduced peripheral vascular resistance. Olmesartan is an angiotensin II receptor blocker (ARB) that selectively blocks AT1 receptors, inhibiting vasoconstriction and aldosterone secretion.
Combination of reserpine (depletes catecholamines from sympathetic nerve endings) and hydralazine (direct vasodilator, increases cGMP via NO).
AZOR is a combination of amlodipine and olmesartan. Typical adult dose: one tablet orally once daily. Available strengths: amlodipine/olmesartan 5mg/20mg, 5mg/40mg, 10mg/20mg, 10mg/40mg. Dose can be titrated based on blood pressure response.
1 tablet (containing reserpine 0.1 mg and hydralazine 25 mg) orally once daily; may increase to twice daily if needed. Maximum dose: 2 tablets per day.

Amlodipine: 30-50 h (terminal); supports once-daily dosing. Olmesartan: 10-15 h (terminal); once-daily dosing effective
Reserpine: ~50-100 hours (biphasic; terminal phase 4.5-11 days due to enterohepatic circulation and tissue binding). Hydralazine: 2-8 hours (rapid acetylators 30-50 min, slow acetylators 2-8 hours); longer in renal impairment.
Renal: 90% (amlodipine: 60% as metabolites, 10% as parent; olmesartan: 35-50% as parent via urine, rest in feces via bile). Fecal: 10%
Reserpine: <1% unchanged in urine; extensive hepatic metabolism followed by renal and fecal excretion. Hydralazine: 80-90% renal; 10% fecal; 1-2% unchanged in urine; polymorphic acetylation (rapid/slow acetylators) affects clearance.
