How Irbesartan Works
Irbesartan works by blocking the action of a natural substance called angiotensin II, which causes blood vessels to tighten. By inhibiting this substance, irbesartan helps to relax and widen blood vessels.
This action lowers blood pressure and improves blood flow, reducing the strain on the heart.
As an angiotensin II receptor blocker, it specifically targets receptors on blood vessels to prevent tightening.
