Angiotensin Converting Enzyme (ACE) Inhibitors are a medication that is used to help treat hypertension, also known as high blood pressure, as well as prevent heart failure. 

Captopril belongs to a group of medications known as Angiotensin Converting Enzyme Inhibitors, also known simply as ACE inhibitors. ACE inhibitors work by widening the blood vessels, making it easier for your heart to pump blood through them.
