How Enalapril Works

Enalapril works by inhibiting the angiotensin-converting enzyme (ACE), which plays a role in the body’s regulation of blood pressure.

By blocking this enzyme, Enalapril helps to relax and widen blood vessels, making it easier for the heart to pump blood around the body.

This action helps to lower blood pressure and can improve symptoms of heart failure.
