Candesartan is an angiotensin receptor blocker used mainly for the treatment of high blood pressure and congestive heart failure. Candesartan has a very low maintenance dose. Like olmesartan, the metabolism of the drug is unusual as it is a cascading prodrug. Candesartan has good bioavailibility and is the most potent by weight of the AT-1 receptor antagonists. It was patented in 1990 and approved for medical use in 1997.
