Olmesartan medoxomil and hydrochlorothiazide tablets are a combination of an angiotensin II receptor antagonist (AT 1 subtype), olmesartan medoxomil, and a thiazide diuretic, hydrochlorothiazide (HCTZ). Olmesartan medoxomil is 1H-Imidazole-5-Carboxylic Acid, 4-(1-Hydroxy-1-Methylethyl)-2-Propyl-1-[[2’-1H-Tetrazol-5yl)[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 and its structural formula is: Olmesartan medoxomil is a white to off white powder with a molecular weight of 558.59. It is slightly soluble in acetone and methanol, very slightly soluble in ethanol and practically insoluble in water. Hydrochlorothiazide is 6-chloro-3,4-dihydro-2 H -1,2,4-benzo-thiadiazine-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 is a white, or practically white, practically odorless, crystalline powder with a molecular weight of 297.74. Hydrochlorothiazide is freely soluble in sodium hydroxide solution, in n-butyl amine and in dimethylformamide; very slightly soluble in water, sparingly soluble in methanol, insoluble in ether, in chloroform and in dilute mineral acids. Olmesartan medoxomil and hydrochlorothiazide tablets are available for oral administration in tablets containing 20 mg or 40 mg of olmesartan medoxomil combined with 12.5 mg of hydrochlorothiazide, or 40 mg of olmesartan medoxomil combined with 25 mg of hydrochlorothiazide. Inactive ingredients include: hydroxy propyl cellulose, hypromellose, iron oxide red, iron oxide yellow, lactose monohydrate, low substituted hydroxy propyl cellulose, magnesium stearate, microcrystalline cellulose, talc and titanium dioxide. olme-hctz-structure-1 olme-hctz-structure-2
