How it works
EnalaprilLopressor
Enalapril is an angiotensin converting enzyme (ACE) inhibitor. It blocks a chemical that tightens blood vessels. This makes blood vessels relax, which lowers blood pressure and allows more blood and oxygen to get to your heart and other organs.Lopressor (metoprolol tartrate) is a beta blocker. It lowers blood pressure by slowing your heart rate, relaxing blood vessels, and lowering the body's fight-or-flight response.
