KOMBIGLYZE XR (saxagliptin and metformin HCl 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. 13,7 ]dec-1-yl)acetyl]-2-azabicyclo[3.1.0]hexane-3-carbonitrile, monohydrate or (1 S ,3 S ,5 S )-2-[(2 S )-2-Amino-2-(3-hydroxyadamantan-1-yl)acetyl]-2-azabicyclo[3.1.0]hexane-3-carbonitrile hydrate. The empirical 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, crystalline powder. It is sparingly soluble in water at 24°C ± 3°C, slightly soluble in ethyl acetate, and soluble in methanol, ethanol, isopropyl alcohol, acetonitrile, acetone, and polyethylene glycol 400 (PEG 400). saxagliptin structure Metformin HCl Metformin HCl ( N,N -dimethylimidodicarbonimidic diamide HCl) is a white to off-white crystalline compound 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 is practically insoluble in acetone, ether, and chloroform. The pK a of metformin is 12.4. The pH of a 1% aqueous solution of metformin HCl is 6.68. The structural formula is: metformin hydrochloride structural formula KOMBIGLYZE XR KOMBIGLYZE XR is available for oral administration as tablets containing either 5.58 mg saxagliptin HCl (anhydrous) equivalent to 5 mg saxagliptin and 500 mg metformin HCl (KOMBIGLYZE XR 5 mg/500 mg), or 5.58 mg saxagliptin HCl (anhydrous) equivalent to 5 mg saxagliptin and 1,000 mg metformin HCl (KOMBIGLYZE XR 5 mg/1,000 mg), or 2.79 mg saxagliptin HCl (anhydrous) equivalent to 2.5 mg saxagliptin and 1,000 mg metformin HCl (KOMBIGLYZE XR 2.5 mg/1,000 mg). Each film-coated tablet of KOMBIGLYZE XR contains the following inactive ingredients: carboxymethylcellulose sodium, hypromellose 2208, and magnesium stearate. The 5 mg/500 mg strength tablet of KOMBIGLYZE XR also contains microcrystalline cellulose and hypromellose 2910. In addition, the film coatings contain the following inactive ingredients: polyvinyl alcohol, polyethylene glycol 3350, titanium dioxide, talc, and iron oxides. 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.
