Benazepril is an angiotensin-converting enzyme (ACE) inhibitor primarily prescribed to manage high blood pressure and heart failure. It works by blocking the conversion of angiotensin I to angiotensin II—a potent vasoconstrictor—thereby relaxing blood vessels, lowering blood pressure, and reducing the heart's workload. This mechanism not only helps to improve overall blood flow but also contributes to the protection of the kidneys by reducing protein loss, especially in patients with chronic kidney disease. Benazepril is typically administered orally, with dosage tailored to the patient's specific condition and response to therapy.
