Candesartan cilexetil and hydrochlorothiazide tablets combines an angiotensin II receptor (type AT 1 ) antagonist and a diuretic, hydrochlorothiazide. Candesartan cilexetil, USP a nonpeptide, is chemically described as (±)-1-Hydroxyethyl 2-ethoxy-1-[ p -( o -1 H -tetrazol-5- ylphenyl)benzyl]-7-benzimidazolecarboxylate, cyclohexyl carbonate (ester). Its empirical formula is C 33 H 34 N 6 O 6 , and its structural formula is Candesartan cilexetil USP is a white to off-white powder with a molecular weight of 610.67. It is practically insoluble in water and sparingly soluble in methanol. Candesartan cilexetil USP is a racemic mixture containing one chiral center at the cyclohexyloxycarbonyloxy ethyl ester group. Following oral administration, candesartan cilexetil USP undergoes hydrolysis at the ester link to form the active drug, candesartan, which is achiral. Hydrochlorothiazide USP is 6-chloro-3,4-dihydro-2 H -1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Its empirical formula is C 7 H 8 ClN 3 O 4 S 2 and its structural formula is Hydrochlorothiazide USP is a white, or practically white, crystalline powder with a molecular weight of 297.72, which is slightly soluble in water, but freely soluble in sodium hydroxide solution. Candesartan cilexitil and hydrochlorothiazide tablets are available for oral administration in three tablet strengths of candesartan cilexetil USP and hydrochlorothiazide USP. Candesartan cilexetil and hydrochlorothiazide tablets 16 mg/12.5 mg contain 16 mg of candesartan cilexetil USP and 12.5 mg of hydrochlorothiazide USP. Candesartan cilexetil and hydrochlorothiazide tablets 32 mg/12.5 mg contain 32 mg of candesartan cilexetil USP and 12.5 mg of hydrochlorothiazide USP. Candesartan cilexetil and hydrochlorothiazide tablets 32 mg/25 mg contain 32 mg of candesartan cilexetil USP and 25 mg of hydrochlorothiazide USP. The inactive ingredients of the tablets are carboxymethylcellulose calcium, hydroxypropyl cellulose, lactose monohydrate, magnesium stearate, corn starch, glycerin, and ferric oxide (yellow). Ferric oxide (red) is also added to the 16 mg/12.5 mg and 32 mg/25 mg tablets as colorant. cande-structure HCTZ-structure
