Ramipril for the prevention and treatment of cardiovascular disease.
OBJECTIVE
To evaluate the effectiveness of ramipril in the prevention and treatment of cardiovascular disease and determine its need for inclusion on a formulary.


METHODS
A MEDLINE and PubMed database search was conducted (1987-May 2002). Only journals written in the English language were selected for review. DATA EXTRACTION AND STUDY SELECTION: Articles reporting the use of ramipril in humans were evaluated. Emphasis was placed on randomized, controlled trials assessing efficacy.


RESULTS
Ramipril is an angiotensin-converting enzyme (ACE) inhibitor that exerts its effects through inhibition of the renin-angiotensin-aldosterone system. It exhibits a safety profile that is similar to that of other ACE inhibitors and is comparable in cost to the majority of the available agents. Clinical trials have proven the effectiveness of ACE inhibitors in the treatment of hypertension, heart failure, and nephropathy. Ramipril, however, is the only ACE inhibitor currently approved for the prevention of cardiovascular events in high-risk patients without evidence of left-ventricular dysfunction or heart failure, based on the results of the HOPE (Heart Outcomes Prevention Evaluation) trial. Whether this effect is specific to ramipril has yet to be proven. This article emphasizes the major trials involving ramipril including the AIRE (Acute Infarction Ramipril Efficacy), REIN (Ramipril Efficacy in Nephropathy), and HOPE trials.


CONCLUSIONS
Although similar to other ACE inhibitors in many aspects, it cannot be assumed that the benefits shown with ramipril in the HOPE trial are a class effect. Ongoing trials should help to clarify this matter. Until this time, current evidence justifies the inclusion of ramipril on a formulary.
