The following information is a summary about Lotrel. It is not intended to replace a doctor's instructions.
What is Lotrel?
Amlodipine is in a group of drugs called calcium channel blockers. Amlodipine relaxes (widens) blood vessels and improves blood flow.
Benazepril is in a group of drugs called ACE inhibitors. ACE stands for angiotensin converting enzyme. Benazepril also widens blood vessels and prevents the body from retaining water.
Lotrel is used to treat high blood pressure (hypertension). It is usually given after other blood pressure medications have been tried without successful treatment.
Lotrel may also be used for purposes other than those listed in this medication guide.
