How Does It Work?

Enalapril is part of a class of drugs called ACE inhibitors. ACE stands for angiotensin-converting enzyme. The medication helps to block the angiotensin-converting enzyme, which is normally part of a reaction in the body that causes the blood vessels to narrow (constrict). By blocking this enzyme, it causes blood vessels to relax, which can lower blood pressure.
