sitagliptin and metformin hydrochloride - Medication Listings

Sitagliptin and metformin hydrochloride extended-release tablets for oral use contain two antihyperglycemic medications: sitagliptin and metformin hydrochloride. 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). All doses of sitagliptin and metformin hydrochloride extended-release tablets contain the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, dibasic calcium phosphate anhydrous, ferric oxide yellow, hypromellose, magnesium stearate, malic acid, microcrystalline cellulose, povidone, pregelatinized starch (maize) and sodium stearyl fumarate. In addition, the film-coating for all doses contains the following inactive ingredients: polyethylene glycol, polyvinyl alcohol-partially hydrolyzed, iron oxide yellow, talc and titanium dioxide. Additionally, sitagliptin and metformin hydrochloride extended-release tablets 50 mg/500 mg and 100 mg/1,000 mg tablets film-coating contain the inactive ingredient red iron oxide and 50 mg/1,000 mg and 100 mg/1,000 mg tablets film-coating contain the FD&C yellow#6 Aluminum Lake.
