DUETACT tablets are a thiazolidinedione and a sulfonylurea combination product that contains two oral antihyperglycemic agents: pioglitazone and glimepiride. The concomitant use of pioglitazone and a sulfonylurea, the class of drugs that includes glimepiride, has been previously approved based on clinical trials in patients with type 2 diabetes inadequately controlled on a sulfonylurea. Additional efficacy and safety information about pioglitazone and glimepiride monotherapies may be found in the prescribing information for each individual drug. Pioglitazone is an oral antidiabetic medication. 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 is an odorless, white crystalline 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. Glimepiride is an oral sulfonylurea chemically identified as 1-[[ p -[2-(3-ethyl-4-methyl-2-oxo-3-pyrroline-1-carboxamido)ethyl]phenyl]sulfonyl]-3-(trans-4-methylcyclohexyl)-urea (C 24 H 34 N 4 O 5 S) with a molecular weight of 490.62. Glimepiride is a white to yellowish-white, crystalline, odorless to practically odorless powder and is practically insoluble in water. The structural formula is: DUETACT is available as a tablet for oral administration containing 30 mg pioglitazone (as the base) with 2 mg glimepiride (30 mg/2 mg) or 30 mg pioglitazone (as the base) with 4 mg glimepiride (30 mg/4 mg) formulated with the following excipients: croscarmellose sodium NF, lactose monohydrate NF, magnesium stearate NF, hydroxypropyl cellulose NF, polysorbate 80 NF, and microcrystalline cellulose NF. pio-chem structure.jpg glim-chem structure.jpg
