Quinapril (Accupril, Accuretic) is an angiotensin-converting enzyme (ACE) inhibitor, one of a class of drugs that lowers blood pressure by blocking the formation of a substance that contracts blood vessels. Quinapril works by relaxing blood vessels, thereby lowering blood pressure and increasing the supply of blood and oxygen to the heart.
