The expanding role of angiotensin converting enzyme inhibitors in the management of hypertension.

Angiotensin converting enzyme (ACE) inhibitors are increasingly important in antihypertensive therapy because of their efficacy, tolerability, and specific benefits in subsets of patients. They are pharmacologically diverse. Whereas most benefits have been proven with older agents (captopril, enalopril), newer agents, such as benazepril, quinapril, and ramipril, offer potential advantages that remain to be proven.
