Losartan potassium and hydrochlorothiazide tablets, 50/12.5 mg, losartan potassium and hydrochlorothiazide tablets, 100/12.5 mg and losartan potassium and hydrochlorothiazide tablets, 100/25 mg combine an angiotensin II receptor blocker acting on the AT 1 receptor subtype and a diuretic, hydrochlorothiazide. Losartan potassium, USP a non-peptide molecule, is chemically described as 2-butyl-4-chloro-1-[ p- ( o -1 H -tetrazol-5-ylphenyl)benzyl]imidazole-5-methanol monopotassium salt. Its empirical formula is C 22 H 22 ClKN 6 O, and its structural formula is: Losartan potassium, USP is a white to off-white free-flowing crystalline powder with a molecular weight of 461.01. It is freely soluble in water, soluble in alcohols, and slightly soluble in common organic solvents, such as acetonitrile and methyl ethyl ketone. Oxidation of the 5-hydroxymethyl group on the imidazole ring results in the active metabolite of losartan. Hydrochlorothiazide, USP is 6-chloro-3,4-dihydro-2 H -1,2,4-benzothiadiazine-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, USP is a white, or practically white, crystalline powder with a molecular weight of 297.74, which is slightly soluble in water, but freely soluble in sodium hydroxide solution. Losartan potassium and hydrochlorothiazide tablets, USP are available for oral administration in three tablet combinations of losartan and hydrochlorothiazide.
