Exforge HCT is a fixed combination of amlodipine, valsartan, and hydrochlorothiazide. Exforge HCT contains the besylate salt of amlodipine, a dihydropyridine calcium channel blocker (CCB). Amlodipine besylate, USP is a white to pale yellow crystalline powder, slightly soluble in water and sparingly soluble in ethanol. Amlodipine besylate’s chemical name is 3-Ethyl 5-methyl (±)-2-[(2-aminoethoxy)methyl]-4-( o -chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridinedicarboxylate, monobenzenesulfonate; its structural formula is: Its empirical formula is C 20 H 25 ClN 2 O 5 •C 6 H 6 O 3 S and its molecular weight is 567.1. Valsartan, USP is a nonpeptide, orally active, and specific angiotensin II antagonist acting on the AT 1 receptor subtype. Valsartan is a white to practically white fine powder, soluble in ethanol and methanol and slightly soluble in water. Valsartan’s chemical name is N-(1-oxopentyl)-N-[[2′-(1 H -tetrazol-5-yl)[1,1′-biphenyl]-4-yl]methyl]-L-valine; its structural formula is: Its empirical formula is C 24 H 29 N 5 O 3 and its molecular weight is 435.5. Hydrochlorothiazide, USP is a white, or practically white, practically odorless, crystalline powder. It is slightly soluble in water; freely soluble in sodium hydroxide solution, in n -butylamine, and in dimethylformamide; sparingly soluble in methanol; and insoluble in ether, in chloroform, and in dilute mineral acids. Hydrochlorothiazide is chemically described as 6-chloro-3,4-dihydro-2 H -1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Hydrochlorothiazide is a thiazide diuretic. Its empirical formula is C 7 H 8 ClN 3 O 4 S 2 , its molecular weight is 297.73, and its structural formula is: Exforge HCT (amlodipine, valsartan, and hydrochlorothiazide) is available as film-coated tablets containing amlodipine besylate (6.9 mg or 13.9 mg, equivalent to 5 mg or 10 mg of amlodipine respectively), with valsartan 160 mg or 320 mg, and hydrochlorothiazide 12.5 mg or 25 mg, providing for the following available combinations: 5/160/12.5 mg, 10/160/12.5 mg, 5/160/25 mg, 10/160/25 mg, and 10/320/25 mg. The inactive ingredients for all strengths of the tablets include microcrystalline cellulose; crospovidone; colloidal anhydrous silica; magnesium stearate; hypromellose, macrogol 4000, and talc. Additionally, the 5/160/12.5 mg strength contains titanium dioxide; the 10/160/12.5 mg strength contains titanium dioxide and yellow and red iron oxides; the 5/160/25 mg strength contains titanium dioxide and yellow iron oxide, and the 10/160/25 mg and 10/320/25 mg strengths both contain yellow iron oxide. amlodipine structural formula Valsartan structural formula Hydrochlorothiazide structural formula
