Pioglitazone and metformin hydrochloride tablets, USP are a thiazolidinediones and biguanide combination product that contains two oral antidiabetic medications: pioglitazone hydrochloride and metformin hydrochloride. Pioglitazone [(±)-5-[[4-[2-(5-ethyl-2-pyridinyl) ethoxy]phenyl]methyl]-2,4-] thiazolidinedione monohydrochloride contains one asymmetric carbon, and the compound is synthesized and used as the racemic mixture. The two enantiomers of pioglitazone interconvert in vivo . No differences were found in the pharmacologic activity between the two enantiomers. The structural formula is as shown: Pioglitazone hydrochloride USP is an off-white to pale yellow color powder that has a molecular formula of C 19 H 20 N 2 O 3 S•HCl and a molecular weight of 392.90 daltons. It is soluble in N,N -dimethylformamide, slightly soluble in anhydrous ethanol, very slightly soluble in acetone and acetonitrile, practically insoluble in water, and insoluble in ether. Metformin hydrochloride USP ( 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 and is practically insoluble in acetone, ether, and chloroform. The pKa of metformin is 12.4. The pH of a 1% aqueous solution of metformin hydrochloride is 6.68. The structural formula is as shown: Pioglitazone and metformin hydrochloride is available as a tablet for oral administration containing 15 mg pioglitazone (as the base) with 500 mg metformin hydrochloride USP (15 mg/500 mg) or 15 mg pioglitazone (as the base) with 850 mg metformin hydrochloride USP (15 mg/850 mg) formulated with the following excipients: carboxymethylcellulose calcium, hydroxypropyl cellulose, hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol 6000, talc, and titanium dioxide.
