Candesartana Cilexetila CAS:145040-37-5

Candesartan cilexetil is a prodrug of the potent, long-acting, and selective angiotensin II type 1 receptor AT1 antagonist, candesartan. It is rapidly hydrolyzed to candesartan during gastrointestinal absorption. After hydrolysis of candesartan cilexetil to candesartan during gastrointestinal absorption, candesartan selectively competes with angiotensin II for the binding of the angiotensin II receptor subtype 1 AT1 in vascular smooth muscle, blocking angiotensin II-mediated vasoconstriction and inducing vasodilatation. In addition, antagonism of AT1 in the adrenal gland inhibits angiotensin II-stimulated aldosterone synthesis and secretion by the adrenal cortex; sodium and water excretion increase, followed by a reduction in plasma volume and blood pressure.
