Sitagliptin Sitagliptin is an orally-active inhibitor of the DPP-4 enzyme. Sitagliptin free base drug substance is used to manufacture sitagliptin and metformin hydrochloride extended-release tablets. Sitagliptin free base is described chemically as 7-[(3R)-3-amino-1-oxo-4-(2,4,5-trifluorophenyl)butyl]-5,6,7,8-tetrahydro-3-(trifluoromethyl)-1,2,4-triazolo[4,3-α]pyrazine with an empirical formula of C 16 H 15 F 6 N 5 O and a molecular weight of 407.31. The structural formula is: Sitagliptin free base is a white to off-white, non-hygroscopic powder. It is soluble in methanol and slightly soluble in water. Metformin hydrochloride Metformin hydrochloride ( N , N -dimethylimidodicarbonimidic diamide hydrochloride) is a white crystalline powder with a molecular formula of C 4 H 11 N 5 •HCl and a molecular weight of 165.62. Metformin hydrochloride is freely soluble in water, slightly soluble in ethanol (95%), practically insoluble in acetone and in methylene chloride. The pK a of metformin hydrochloride is 12.4. The pH of a 1% aqueous solution of metformin hydrochloride is 6.68. The structural formula is as shown: Sitagliptin and metformin hydrochloride extended-release tablets Sitagliptin and metformin hydrochloride extended-release tablets are available as film-coated tablets containing: 50 mg sitagliptin and 389.93 mg of metformin equivalent to 500 mg metformin hydrochloride (sitagliptin and metformin hydrochloride extended-release tablets 50/500). 50 mg sitagliptin and 779.86 mg of metformin equivalent to 1,000 mg metformin hydrochloride (sitagliptin and metformin hydrochloride extended-release tablets 50/1,000). 100 mg sitagliptin and 779.86 mg of metformin equivalent to 1,000 mg metformin hydrochloride (sitagliptin and metformin hydrochloride extended-release tablets 100/1,000).
