Irbesartan works by blocking the action of angiotensin II, a chemical in the body that causes blood vessels to tighten and narrow. By blocking the receptors that angiotensin II acts on, irbesartan allows blood vessels to relax and widen, which in turn reduces blood pressure, improves blood flow, and reduces the workload on the heart.
