Generic Name: amlodipine and benazepril (am LOE di peen and ben AY ze pril)
Brand Names: Lotrel

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.

You should not use this medication if you are allergic to amlodipine (Norvasc) or benazepril (Lotensin), or if you have ever had angioedema (hives or severe swelling of deep skin tissues sometimes caused by allergic reaction).
