Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACEON (perindopril) is an angiotensin-converting enzyme (ACE) inhibitor. It inhibits ACE, which converts angiotensin I to angiotensin II, a potent vasoconstrictor. This results in decreased vasopressor activity, reduced aldosterone secretion, and lower peripheral vascular resistance, leading to antihypertensive effects.
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, decreased aldosterone secretion, and reduced blood pressure.
Initial: 4 mg orally once daily; titrate to 8-32 mg daily in 1-2 divided doses. Typical maintenance: 8-16 mg daily.
Oral, 1 capsule (amlodipine 2.5-10 mg / benazepril 10-40 mg) once daily. Start with amlodipine 2.5 mg / benazepril 10 mg, titrate based on response.

Perindoprilat: terminal half-life ~30 hours (up to 120 hours in elderly or heart failure due to prolonged terminal phase from slow dissociation from ACE binding); perindopril: ~1.5 hours.
Amlodipine: terminal elimination half-life 30-50 hours (mean ~35 h), allowing once-daily dosing. Benazeprilat: effective half-life 10-11 hours; terminal half-life ~22 hours, with prolonged effects in renal impairment.
Renal: approximately 30% as perindopril and 20% as perindoprilat; fecal: approximately 50% as metabolites.
Amlodipine: ~90% metabolized to inactive metabolites, ~10% excreted unchanged in urine; metabolites excreted renally (~60%) and fecally (~20-25%). Benazepril: hydrolyzed to benazeprilat, which undergoes renal excretion (~33% as unchanged drug and metabolites) and biliary/fecal excretion (~33%), with the remainder via other routes.
