CAPTOPRIL is an antihypertensive (blood pressure lowering agent) known as an ACE inhibitor. Captopril controls high blood pressure (hypertension) by relaxing blood vessels; it is not a cure. High blood pressure levels can damage your kidneys, and may lead to a stroke or heart failure. Captopril also can help to treat heart failure (heart does not pump strongly enough) and certain kidney disorders.
