How does Enalapril work?

  • Enalapril works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly and the heart can pump blood more efficiently.
  • ACE inhibitors prevent the conversion of angiotensin I to angiotensin II by ACE, thereby attenuating the vasoconstrictive effects of angiotensin II peripherally (afterload reduction) and in the kidney (causing efferent arteriolar dilation).
  • They also decrease the release of aldosterone into blood preventing sodium and water retention.
  • ACE also is responsible for the breakdown of bradykinin (a vasodilator), and ACE inhibitors result in an accumulation of bradykinin, which may have beneficial vasodilatory effects.

How to take Enalapril?

  • Enalapril comes as an immediate and extended-release (long-acting) tablet to take by mouth.
