AMLODIPINE BESYLATE; BENAZEPRIL HYDROCHLORIDE vs BRINSUPRI
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, decreased aldosterone secretion, and reduced blood pressure.
BRINSUPRI is a novel oral cyclin-dependent kinase (CDK) inhibitor that selectively inhibits CDK4 and CDK6, thereby blocking phosphorylation of the retinoblastoma (Rb) protein and preventing G1-to-S phase cell cycle progression. This induces cell cycle arrest in cancer cells with intact Rb function.
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.
4 mg orally once daily, with or without food.

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.
Terminal elimination half-life is approximately 20-30 hours in healthy adults, allowing once-daily dosing. In renal impairment (CrCl <30 mL/min), half-life may extend to >50 hours, requiring dose adjustment.
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.
Primarily renal excretion as unchanged drug (70-85%) and minor fecal elimination (10-15%). Biliary excretion accounts for <5%.
