|Type of medicine||Angiotensin-II receptor antagonist|
Candesartan is an angiotensin receptor blocker (also called an angiotensin-II receptor antagonist or an AIIRA). It is used to treat hypertension (high blood pressure) and heart failure (a condition where the pumping action of the heart is reduced). People with high blood pressure often do not feel unwell but, left untreated, high blood pressure can harm the heart and damage blood vessels.
Candesartan works by blocking the effect of a chemical called angiotensin II which is made in your bloodstream. Angiotensin II causes your blood vessels to narrow, so by blocking this effect, candesartan allows your blood vessels to relax and widen. As this happens, the pressure of blood within your blood vessels is reduced. This also makes it easier for your heart to pump blood around your body.
