What is this medication for?

Quinapril belongs to the class of medications called angiotensin converting enzyme (ACE) inhibitors, a class used to lower blood pressure. Quinapril works by relaxing blood vessels and by making the heart pump more efficiently. It is used for the treatment of high blood pressure, which lowers the risk of having a heart attack or stroke.  It is also used with other medications to treat heart failure.
