is enalapril a beta blocker?
<answer> No, enalapril is not a beta blocker, it is an ACE inhibitor. <context> Enalapril is not a beta blocker, it is an ACE (Angiotensin Converting Enzyme) inhibitor. This enzyme converts angiotensin I to angiotensin II, which is a vasoconstrictor substance. So, as long as ACE is inhibited, there won't be any contracting effect on vessels triggered by Angiotensin II. Views.
