Indications & Uses

Pharmacology

Candesartan Cilexetil is an ester prodrug that is hydrolysed to its active form, Candesartan, during absorption from the gastrointestinal tract. Candesartan is an angiotensin II receptor (type AT1) antagonist. It blocks the vasoconstrictor and aldosterone secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland.
