What is Benazepril?

Plain description, key identifiers and synonyms

Benazepril is a benzazepine that is benazeprilat in which the carboxy group of the 2-amino-4-phenylbutanoic acid moiety has been converted to the corresponding ethyl ester. It is used (generally as its hydrochloride salt) as a prodrug for the angiotensin-converting enzyme inhibitor benazeprilat in the treatment of hypertension and heart failure. It has a role as an EC 3.4.15.1 (peptidyl-dipeptidase A) inhibitor and a prodrug. It is an ethyl ester, a lactam, a benzazepine and a dicarboxylic acid monoester. It is functionally related to a benazeprilat. It is a conjugate base of a benazepril(1+).

Benazepril is a chemical compound ACE inhibitor.
