Benazepril is a medication that belongs to a class of drugs known as angiotensin-converting enzyme (ACE) inhibitors. It is primarily used to treat high blood pressure, but it is also commonly employed in the treatment of heart failure. Benazepril works by relaxing the walls of blood vessels, making it easier for the heart to pump blood throughout the body. Some common synonyms of benazepril include Lotensin, Cibacen, Fortekor, and Renitec. These synonyms refer specifically to the brand names of benazepril manufactured by different pharmaceutical companies but contain the same active ingredient. Your doctor will prescribe the brand name that is best for your needs.
