Angiotensin inhibitor or blocker?

For controlling blood pressure, an ACE inhibitor is a good place to start.

Doctors are often quick to prescribe new drugs even when the "old" ones work perfectly fine. That has certainly been the case with newer angiotensin receptor blockers (ARBs) and older ACE inhibitors, two classes of drugs commonly used to treat high blood pressure (hypertension). Both drugs target a molecule known as angiotensin II, but in different ways.
