It is an angiotensin-converting-enzyme (ACE) inhibitor. The angiotensin I is converted to angiotensin II in the presence of an angiotensin-converting enzyme (ACE). The Angiotensin II constricts blood vessels, increasing blood pressure. By inhibiting the ACE, enalaprilat, the active metabolite of enalapril, decreases levels of angiotensin II leading to less vasoconstriction a decreased blood pressure.
