How Candesartan Works

Candesartan works by blocking the action of a natural substance in the body called angiotensin II. This substance usually causes blood vessels to tighten.

By blocking angiotensin II, candesartan helps relax and widen blood vessels, making it easier for the heart to pump blood and reducing blood pressure.

This relaxation of blood vessels can also help improve blood flow and reduce the workload on the heart.
