Understanding how it works, its potential side effects, and important precautions can help you use irbesartan safely and effectively.
How Irbesartan Works
Irbesartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs). Angiotensin II is a hormone that causes blood vessels to constrict, leading to increased blood pressure. Irbesartan works by blocking the action of angiotensin II, allowing the blood vessels to relax and blood to flow more easily. This, in turn, lowers blood pressure and reduces the workload on the heart.
