alogliptin and pioglitazone - Generic Medications

OSENI tablets contain two oral antihyperglycemic drugs used in the management of type 2 diabetes mellitus: alogliptin and pioglitazone. Alogliptin Alogliptin is a selective, orally bioavailable inhibitor of the enzymatic activity of dipeptidyl peptidase-4 (DPP-4). Chemically, alogliptin is prepared as a benzoate salt, which is identified as 2-({6-[(3 R )-3-aminopiperidin-1-yl]-3-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2 H )-yl}methyl)benzonitrile monobenzoate. It has a molecular formula of C 18 H 21 N 5 O 2 ∙C 7 H 6 O 2 and a molecular weight of 461.51 daltons. The structural formula is: Alogliptin benzoate is a white to off-white crystalline powder containing one asymmetric carbon in the aminopiperidine moiety. It is soluble in dimethylsulfoxide, sparingly soluble in water and methanol, slightly soluble in ethanol and very slightly soluble in octanol and isopropyl acetate. Pioglitazone Chemically, pioglitazone is prepared as hydrochloride (HCl) salt, which is identified as (±)-5-[[4-[2-(5-ethyl-2-pyridinyl)ethoxy]phenyl]methyl]-2,4-thiazolidinedione monohydrochloride. It has a molecular formula of C 19 H 20 N 2 O 3 S∙HCl and a molecular weight of 392.90 daltons. The structural formula is: Pioglitazone HCl is an odorless white crystalline powder that contains one asymmetric carbon in the thiazolidinedione moiety. The synthetic compound is a racemate and the two enantiomers of pioglitazone interconvert in vivo . 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. OSENI is available as a fixed-dose combination tablet for oral administration containing 34 mg alogliptin benzoate equivalent to 25 mg alogliptin and any of the following strengths of pioglitazone HCl: 16.53 mg pioglitazone HCl equivalent to 15 mg pioglitazone (25 mg/15 mg) 33.06 mg pioglitazone HCl equivalent to 30 mg pioglitazone (25 mg/30 mg) 49.59 mg pioglitazone HCl equivalent to 45 mg pioglitazone (25 mg/45 mg) OSENI is also available as a fixed-dose combination tablet for oral administration containing 17 mg alogliptin benzoate equivalent to 12.5 mg alogliptin for the following strength of pioglitazone HCl: 33.06 mg pioglitazone HCl equivalent to 30 mg pioglitazone (12.5 mg/30 mg) OSENI tablets contain the following inactive ingredients: croscarmellose sodium, hydroxypropyl cellulose, lactose monohydrate, magnesium stearate, mannitol, and microcrystalline cellulose; the tablets are film-coated with ferric oxide (yellow and/or red), hypromellose, polyethylene glycol, talc, titanium dioxide, and are marked with printing ink (Red A1 or Gray F1).
