Lotrel

Generic name: amlodipine and benazeprilam-LOE-di-peen-and-ben-AY-ze-pril ]
Drug class: ACE inhibitors with calcium channel blocking agents

Medically reviewed by Sophia Entringer, PharmD. Last updated on Oct 4, 2023.

What is Lotrel?

Lotrel contains a combination of amlodipine and benazepril. Amlodipine is a calcium channel blocker. Amlodipine relaxes (widens) blood vessels and improves blood flow.

Benazepril is an ACE inhibitor. ACE stands for angiotensin converting enzyme. Benazepril also widens blood vessels and also prevents the body from retaining water.

Lotrel is used to treat high blood pressure (hypertension).

Lotrel may also be used for purposes not listed in this medication guide.
