How It Works

Losartan is an angiotensin II receptor blocker that works by blocking the action of a substance in the body called angiotensin II. Angiotensin II causes blood vessels to constrict, which leads to high blood pressure. By blocking the action of angiotensin II, losartan helps to relax and widen blood vessels, lowering blood pressure and making it easier for the heart to pump blood to the rest of the body.
