What is Amlodipine-Benazepril: Uses, Warnings & Interactions

Updated May 14, 2025  •  Published Dec 30, 2020

Amlodipine-benazepril is a generic prescription blood pressure drug that combines two commonly prescribed medications. Benazepril is an ACE inhibitor that relaxes blood vessels. It is typically one of the first drugs healthcare professionals use to treat high blood pressure. Amlodipine is a calcium channel blocker that relaxes the blood vessels and the heart to reduce blood pressure. It, too, is a common first-line treatment for hypertension. Amlodipine-benazepril capsules are taken once daily at the same time each day.
