Olmesartan medoxomil, amlodipine and hydrochlorothiazide provided as a tablet for oral administration, is a fixed combination of olmesartan medoxomil (ARB), amlodipine (CCB), and hydrochlorothiazide (thiazide diuretic). Olmesartan medoxomil, a prodrug, is hydrolyzed to olmesartan during absorption from the gastrointestinal tract. The olmesartan medoxomil component of olmesartan medoxomil, amlodipine and hydrochlorothiazide tablet is chemically described as 1H-Imadazole-5-carboxylic acid, 4-(1-hydroxy-1-methyl-ethyl)- 2-Propyl-1-[[2’-(1H tetrazole-5-yl) [1,1’-biphenyl]-4-yl]methyl-, (5- methyl-2-oxo-1, 3-dioxol-4-yl) methyl ester. Its empirical formula is C 29 H 30 N 6 O 6 . The amlodipine besylate component of olmesartan medoxomil, amlodipine and hydrochlorothiazide tablet is chemically described as 3,5-pyridine dicarboxylic acid, 2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-1,4-dihydro-6-methyl,3-ethyl 5-methyl ester, (±)-monobenzene sulfonate. Its empirical formula is C 26 H 31 CIN 2 O 8 S. The hydrochlorothiazide component of olmesartan medoxomil, amlodipine and hydrochlorothiazide tablet is chemically described as 6-chloro-3, 4-dihydro-2 H-1, 2, 4-benzothiadiazine-7-sulphonamide 1,1- dioxide. Its empirical formula is C 7 H 8 CIN 3 O 4 S 2 . The structural formula for olmesartan medoxomil is: The structural formula for amlodipine besylate is: The structural formula for hydrochlorothiazide is: Olmesartan medoxomil, amlodipine and hydrochlorothiazide tablet contains olmesartan medoxomil USP, a white to off-white, crystalline powder, amlodipine besylate USP, a white or almost white powder, and hydrochlorothiazide USP, a white or practically white, practically odourless, crystalline powder. The molecular weights of olmesartan medoxomil, amlodipine besylate, and hydrochlorothiazide are 558.6, 567.1, and 297.7, respectively. Olmesartan medoxomil USP is practically insoluble in water and in heptane, slightly soluble in ethanol (96%), sparingly soluble in methanol. Amlodipine besylate USP is slightly soluble in water, freely soluble in methanol, sparingly soluble in anhydrous ethanol, slightly soluble in 2-propanol. Hydrochlorothiazide USP is very slightly soluble in water, freely soluble in sodium hydroxide solution, in n-butylamine, and in dimethyl formamide, sparingly soluble in methanol, insoluble in ether, in chloroform and in dilute mineral acids. Each tablet of olmesartan medoxomil, amlodipine and hydrochlorothiazide also contains the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, magnesium stearate, microcrystalline cellulose and pregelatinized starch. The color coating contains iron oxide black, iron oxide red, iron oxide yellow, macrogol, polyvinyl alcohol, talc and titanium dioxide. The botanical source for pregelatinized starch is corn starch. oahfigstruct1 oahfigstruct2 oahfigstruct3
