AMLODIPINE MALEATE; BENAZEPRIL HYDROCHLORIDE vs MAVIK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amlodipine is a dihydropyridine calcium channel blocker that inhibits the influx of calcium ions into vascular smooth muscle and cardiac muscle, leading to vasodilation and reduced peripheral vascular resistance. Benazepril is an angiotensin-converting enzyme (ACE) inhibitor that prevents the conversion of angiotensin I to angiotensin II, resulting in vasodilation and reduced aldosterone secretion.
Angiotensin-converting enzyme (ACE) inhibitor; inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure and reduced cardiac workload.
Initial: 2.5-5 mg amlodipine / 10-20 mg benazepril orally once daily, titrated to 10/40 mg once daily based on response.
Oral, 1-4 mg once daily for hypertension; 2-4 mg once daily for heart failure.

Amlodipine: 30-50 h (terminal), allowing once-daily dosing; benazeprilat: 10-11 h (terminal), effective for 24 h.
Trandolaprilat: terminal half-life ~24 hours (range 15–35 hours) for once-daily dosing; effective half-life ~6–10 hours at steady state.
Renal: Amlodipine 10% unchanged, benazeprilat (active metabolite) 50-60% in urine; biliary/fecal: amlodipine 20-25% as metabolites, benazeprilat 10-20% in feces.
Renal: trandolapril ~33% (as trandolaprilat and metabolites), trandolaprilat ~33% (as unchanged and metabolites); biliary/fecal: ~66% of total radioactivity.
