Mechanism of action

Irbesartan is an angiotensin II receptor blocker (ARB) that selectively antagonizes AT1 receptors on vascular smooth muscle and adrenal tissue. By blocking angiotensin II signaling, it causes vasodilation and reduces sodium and water retention, thereby decreasing blood pressure and reducing cardiac workload. This mechanism also provides renal protection in patients with hypertension and diabetes.
