What drug class is Lisinopril in?

Lisinopril belongs to the class of medications known as ACE inhibitors. This drug class is primarily used to treat high blood pressure and heart failure. ACE stands for Angiotensin-Converting Enzyme, and inhibitors block this enzyme's action, which helps to prevent the conversion of angiotensin I to angiotensin II—a substance that narrows blood vessels and raises blood pressure. By inhibiting this process, lisinopril effectively helps to lower blood pressure, improve blood flow, and enhance oxygen supply to the heart.

This makes ACE inhibitors, like lisinopril, critical in managing cardiovascular conditions, as they can also provide benefits related to kidney health, especially in diabetic patients. Understanding the role of ACE inhibitors is essential for medication assistants, as it allows them to recognize the intended effects and potential side effects associated with these medications, particularly regarding their application in treating hypertension and heart failure.
