Candesartan cilexetil tablets USP, a prodrug, are hydrolyzed to candesartan during absorption from the gastrointestinal tract. Candesartan is a selective AT 1 subtype angiotensin II receptor antagonist. Candesartan cilexetil, a nonpeptide, is chemically described as (±)2-Ethoxy-1-[[2’-(1 H -tetrazol-5-yl)[1,1’-biphenyl]-4-yl]methyl]-1 H -benzimidazole-7-carboxylic acid-1-[[(cyclohexyloxy)carbonyl]oxy]ethyl ester. Its molecular formula is C 33 H 34 N 6 O 6 , and its structural formula is: Candesartan cilexetil, USP is a white or off-white powder with a molecular weight of 610.66. It is practically insoluble in water and sparingly soluble in methanol. Candesartan cilexetil is a racemic mixture containing one chiral center at the cyclohexyloxycarbonyloxy ethyl ester group. Following oral administration, candesartan cilexetil undergoes hydrolysis at the ester link to form the active drug, candesartan, which is achiral. Candesartan cilexetil is available for oral use as tablets containing either 4 mg, 8 mg, 16 mg, or 32 mg of candesartan cilexetil and the following inactive ingredients: carboxymethylcellulose calcium, corn starch, glyceryl stearate, hydroxypropyl cellulose, lactose monohydrate and magnesium stearate. The 8 mg, 16 mg and 32 mg tablets also contain red iron oxide. Candesartan Cilexetil Structural Formula
