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 tablets is chemically described as 2,3-dihydroxy-2-butenyl 4-(1-hydroxy-1-methylethyl)-2-propyl-1-[ p-(o- 1 H -tetrazol-5-ylphenyl)benzyl]imidazole-5-carboxylate, cyclic 2,3-carbonate. Its empirical formula is C 29 H 30 N 6 O 6 . The amlodipine besylate component of olmesartan medoxomil, amlodipine and hydrochlorothiazide tablets is chemically described as 3-ethyl-5-methyl (±)-2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridinedicarboxylate, monobenzenesulphonate. Its empirical formula is C 20 H 25 CIN 2 O 5 •C 6 H 6 O 3 S. The hydrochlorothiazide component of olmesartan medoxomil, amlodipine and hydrochlorothiazide tablets is chemically described as 6-chloro-3,4-dihydro-2 H -1,2,4-benzo-thiazidiazine-7-sulfonamide 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 tablets contains olmesartan medoxomil, a white to light yellowish-white powder or crystalline powder, amlodipine besylate, a white to off-white crystalline powder, and hydrochlorothiazide, a white or practically white, crystalline powder. The molecular weights of olmesartan medoxomil, amlodipine besylate, and hydrochlorothiazide tablets are 558.6, 567.1, and 297.7, respectively. Olmesartan medoxomil is practically insoluble in water and sparingly soluble in methanol. Amlodipine besylate is slightly soluble in water and sparingly soluble in ethanol. Hydrochlorothiazide is slightly soluble in water but freely soluble in sodium hydroxide solution. Each 20/5/12.5 mg tablet contains 20 mg of olmesartan medoxomil, 5 mg of amlodipine besylate and 12.5 mg of hydrochlorothiazide. Each 40/5/12.5 mg tablet contains 40 mg of olmesartan medoxomil, 5 mg of amlodipine besylate and 12.5 mg of hydrochlorothiazide. Each 40/5/25 mg tablet contains 40 mg of olmesartan medoxomil, 5 mg of amlodipine besylate and 25 mg of hydrochlorothiazide. Each 40/10/12.5 mg tablet contains 40 mg of olmesartan medoxomil, 10 mg of amlodipine besylate and 12.5 mg of hydrochlorothiazide. Each 40/10/25 mg tablet contains 40 mg of olmesartan medoxomil, 10 mg of amlodipine besylate and 25 mg of hydrochlorothiazide. Each tablet of olmesartan medoxomil, amlodipine besylate and hydrochlorothiazide also contains the following inactive ingredients: silicified microcrystalline cellulose, pregelatinized starch, croscarmellose sodium, and magnesium stearate. The color coating for 20 /5 /12.5 mg, 40 /5 /25 mg tablets contains titanium dioxide, hypromellose, polyethylene glycol and polysorbate, the color coating for 40/10/25 mg and 40/5/12.5 mg tablets contains polyvinyl alcohol - part dehydrolyzed, titanium dioxide, polyethylene glycol, talc and iron oxide red and the color coating for 40 /10 /12.5 mg tablets polyvinyl alcohol - part dehydrolyzed, titanium dioxide, polyethylene glycol, talc iron oxide yellow and FD&C #6.
