Description: Candesartan is an angiotensin II receptor antagonist used mainly for the treatment of hypertension. Candesartan is marketed as the cyclohexyl 1-hydroxyethyl carbonate (cilexetil) ester, known as candesartan cilexetil. Candesartan cilexetil is metabolised completely by esterases in the intestinal wall during absorption to the active candesartan moieity. The use of a prodrug form increases the bioavailability of candesartan. Despite this, absolute bioavailability is relatively poor at 15% (candesartan cilexetil tablets) to 40% (candesartan cilexetil solution). Its IC50 is 15 µg/kg.
