Saxagliptin and metformin hydrochloride extended-release tablets contain two oral antihyperglycemic medications used in the management of type 2 diabetes mellitus: saxagliptin and metformin HCl. Saxagliptin Saxagliptin is an orally active inhibitor of the dipeptidyl-peptidase-4 (DPP4) enzyme. Saxagliptin monohydrate is described chemically as (1 S ,3 S ,5 S )-2-[(2 S )-2-Amino-2-(3-hydroxytricyclo[3.3.1.1 3,7 ]dec-1-yl)acetyl]-2-azabicyclo[3.1.0]hexane-3-carbonitrile, monohydrate or (1 S ,3 S ,5 S )-2-[(2S)-2-Amino-2-(3-hydroxyadamantan-1-yl)acetyl]-2-azabicyclo[3.1.0]hexane-3-carbonitrile monohydrate. The molecular formula is C 18 H 25 N 3 O 2 •H 2 O and the molecular weight is 333.43. The structural formula is: Saxagliptin monohydrate is a white to light yellow or light brown, non-hygroscopic powder. It is very soluble at room temperate in methanol, freely soluble in ethanol, soluble in acetone, sparingly soluble in ethyl acetate and water, and slightly soluble in 1-octanol. Metformin Hydrochloride, USP Metformin HCl (N,N-dimethyl imido-dicarbonimidic diamide HCl) is a white crystalline powder with a molecular formula of C 4 H 11 N 5 • HCl and a molecular weight of 165.63. Metformin HCl is freely soluble in water, slightly soluble in alcohol, and practically insoluble in acetone and in methylene chloride. The pK a of metformin HCl is 8.6. The structural formula is: Saxagliptin and Metformin Hydrochloride Extended-release Tablets Saxagliptin and metformin hydrochloride extended-release tablets are available for oral administration as tablets containing either 5.58 mg saxagliptin HCl (anhydrous) equivalent to 5 mg saxagliptin and 500 mg metformin HCl, USP (saxagliptin and metformin hydrochloride extended-release tablets 5 mg/500 mg), or 5.58 mg saxagliptin HCl (anhydrous) equivalent to 5 mg saxagliptin and 1,000 mg metformin HCl, USP (saxagliptin and metformin hydrochloride extended-release tablets 5 mg/1,000 mg), or 2.79 saxagliptin HCl (anhydrous) equivalent to 2.5 mg saxagliptin and 1,000 mg metformin HCl, USP (saxagliptin and metformin hydrochloride extended-release tablets 2.5 mg/1,000 mg). Each film-coated tablet of saxagliptin and metformin hydrochloride extended-release tablets contains the following inactive ingredients: colloidal silicon dioxide, hydrochloric acid, hypromellose, iron oxide black, magnesium stearate, microcrystalline cellulose, polyethylene glycol, povidone, propylene glycol, shellac, talc, titanium dioxide. In addition, 5 mg/500 mg tablets contain iron oxide red and iron oxide yellow; 5 mg/1,000 mg tablets contain iron oxide red; 2.5 mg/1,000 mg tablets contain iron oxide yellow. The biologically inert components of the tablet may occasionally remain intact during gastrointestinal transit and will be eliminated in the feces as a soft, hydrated mass. structure1 structure2
