Benazepril is primarily used in the treatment of high blood pressure (hypertension). It helps to relax blood vessels, allowing blood to flow more smoothly and reducing the workload on the heart. This makes it effective in managing conditions like chronic heart failure and improving overall cardiovascular health. Additionally, it is sometimes prescribed to protect kidney function in patients with diabetes, as it can slow the progression of kidney damage. It is often used in combination with other medications to achieve optimal blood pressure control. Regular monitoring is recommended to ensure its effectiveness and to manage potential side effects.
