Amlodipine/benazepril, marketed in the U.S. as Lotrel by Novartis and manufactured as a generic drug by Teva and Sandoz, is an antihypertensive medication which combines a calcium channel blocker (amlodipine besilate) with an angiotensin converting enzyme inhibitor (benazepril). This drug, like similar combinations, is prescribed when either agent alone is not sufficient to bring a person's blood pressure down to target range. As a combination agent, Lotrel shares the adverse reaction profile of both of its individual parts.
