Notes: Candesartan-d4 is intended for use as an internal standard for the quantification of candesartan by GC- or LC-MS. Candesartan is an antagonist of the angiotensin II type 1 (AT1) receptor (Kis = 0.17, 0.12, and 0.12 nM for human AT1, rat AT1A, and rat AT1B recombinant receptors, respectively) and an active metabolite of the prodrug candesartan cilexitil (Item No. 10489).{28032} It is selective for AT1 over AT2 receptors (Ki = 26,500 nM for the human recombinant AT2 receptor). It inhibits angiotensin II-induced contraction of isolated rabbit aortic strips and increases in blood pressure in rats following intravenous administration (ID50 = 0.033 mg/kg).{42295} Formulations containing candesartan have been used in the treatment of hypertension and heart failure.
