Lisinopril vs. Benazepril: Comparing ACE Inhibitors for Blood Pressure and Heart Conditions

Lisinopril and Benazepril are both Angiotensin-Converting Enzyme (ACE) inhibitors, a class of medications primarily used to treat high blood pressure. They work by relaxing blood vessels to improve blood flow and reduce the heart's workload. Patients often compare these drugs due to their similar mechanisms and uses, though there can be differences in specific indications and dosing.

When to ChooseA doctor might prefer Lisinopril if a patient needs treatment for heart failure or has recently had a heart attack, in addition to high blood pressure. It is also indicated for pediatric patients 6 years and older with hypertension.

Bottom Line

Lisinopril and Benazepril are both effective ACE inhibitors for managing high blood pressure, with similar mechanisms and potential side effects. Lisinopril has additional indications for heart failure and post-heart attack treatment. The best choice depends on your specific health conditions, other medications, and your doctor's clinical judgment.

Lisinopril Overview

Lisinopril (Prinivil, Zestril) is one of the most widely prescribed medications in the United States and the most commonly used ACE inhibitor. It lowers blood pressure by relaxing blood vessels, reduces hospitalizations and death in heart failure, and improves survival after a heart attack. It is also used to slow kidney disease progression in people with diabetes. Generic lisinopril is available for as little as $4–$15 per month, making it one of the most cost-effective cardiovascular medications available.
