Benazepril is a medication primarily used to treat high blood pressure, also known as hypertension. It belongs to a class of drugs called ACE inhibitors, which work by relaxing blood vessels, making it easier for the heart to pump blood. This helps lower blood pressure and reduces the risk of heart-related issues. In addition to managing hypertension, benazepril may also be prescribed for heart failure and to protect kidney function in patients with diabetes. It is important for patients to follow their healthcare provider's instructions and report any side effects, such as cough or dizziness, while taking this medication.
