Benazepril is an angiotensin-converting enzyme (ACE) inhibitor commonly prescribed to treat high blood pressure (hypertension) and heart failure. It works by relaxing blood vessels, making it easier for the heart to pump blood and reducing blood pressure. By inhibiting the ACE enzyme, which is responsible for producing a substance that narrows blood vessels, Benazepril helps lower the strain on the heart and improves overall cardiovascular function. This medication is also used to help prevent kidney damage caused by hypertension or diabetes, and it may be used in combination with other medications for a more comprehensive approach to managing heart-related conditions.
