CLINICAL PHARMACOLOGY Mechanism of Action In animals and humans, fosinopril sodium is hydrolyzed by esterases to the pharma- cologically active form, fosinoprilat, a specific competitive inhibitor of angiotensin converting enzyme (ACE). ACE is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vaso- constrictor substance, angiotensin II. Angiotensin I
