Amlodipine, valsartan and hydrochlorothiazide tablets USP are a fixed combination of amlodipine, valsartan, and hydrochlorothiazide. Amlodipine, valsartan and hydrochlorothiazide tablets USP contain the besylate salt of amlodipine, a dihydropyridine calcium channel blocker (CCB). Amlodipine besylate, USP is a white or almost white 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 molecular 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, USP is a white, fine hygroscopic 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 molecular 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 molecular formula is C 7 H 8 ClN 3 O 4 S 2 , its molecular weight is 297.73, and its structural formula is: Amlodipine, valsartan and hydrochlorothiazide is available as film-coated tablets containing amlodipine besylate USP (6.9 mg or 13.9 mg, equivalent to 5 mg or 10 mg of amlodipine respectively), with valsartan USP 160 mg or 320 mg, and hydrochlorothiazide USP 12.5 mg or 25 mg, providing for the following available combinations: 5 mg/160 mg/12.5 mg, 10 mg/160 mg/12.5 mg, 5 mg/160 mg/25 mg, 10 mg/160 mg/25 mg, and 10 mg/320 mg/25 mg.
