How Does Irbesartan Work?

Irbesartan is part of a class of drugs called angiotensin II receptor blockers (ARBs for short). As the name implies, irbesartan blocks angiotensin II receptors.

By blocking the effects of angiotensin II, irbesartan causes blood vessels to relax, which can lower blood pressure.
