20090012184Production of Dosage Forms Comprising a Solid Dispersion of a Microcrystalline Agent - A method is described for the production of dosage forms, which comprise a solid dispersion of a microcrystalline active substance, in which a thermoplastic polymer with a glass transition temperature Tg of at least 40° C. is melted and an active substance is dissolved homogeneously in the melt; crystallization of the active substance is initiated in the mass obtained; and the mass is cooled. Crystallization of the active substance can be initiated by adding a nonsolvent, seed crystals of the active substance or a derivatization reagent. In addition, crystallization can be initiated by holding the mass for a sufficient length of time at a temperature that is below the temperature at which the active substance is completely soluble in the mass.01-08-2009
20100143459PHARMACEUTICAL DOSAGE FORM FOR ORAL ADMINISTRATION OF TYROSINE KINASE INHIBITOR - A pharmaceutical dosage form comprises a solid dispersion product of at least one tyrosine kinase inhibitor, at least one pharmaceutically acceptable polymer, and at least one pharmaceutically acceptable solubilizer.06-10-2010
20100297194FORMULATION FOR ORAL ADMINISTRATION OF APOPTOSIS PROMOTER - An orally deliverable pharmaceutical composition comprises as a sole or first active ingredient a compound of Formula I defined herein or a pharmaceutically acceptable salt thereof, for example ABT-263 free base or ABT-263 bis-HCl salt, dispersed, in a free base equivalent amount of at least about 2.5% by weight of the composition, in a pharmaceutically acceptable carrier; wherein said active ingredient is in solid-state form and/or the composition further comprises, dispersed in the carrier, a pharmaceutically acceptable heavier-chalcogen antioxidant in an amount effective to inhibit oxidation of the active ingredient at a thioether linkage thereof. The composition is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.11-25-2010
20100310648PHARMACEUTICAL DOSAGE FORM FOR ORAL ADMINISTRATION OF A BCL 2 FAMILY INHIBITOR - The invention relates to a pharmaceutical dosage form which comprises a solid dispersion product comprising N-(4-(4-((2-(4-chlorophenyl)-5,5-dimethyl-1-cyclohex-1-en-1-yl)methyl)piperazin-1-yl)benzoyl)-4-(((1R)-3-(morpholin-4-yl)-1-((phenylsulfanyl)methyl)propyl)amino)-3-((trifluoromethyl)sulfonyl)benzenesulfonamide or a salt, hydrate or solvate thereof, at least one pharmaceutically acceptable polymer, and at least one pharmaceutically acceptable solubilizer. The invention is further directed to processes for preparing the pharmaceutical dosage form and to use of the dosage form for treating proliferative disorders.12-09-2010
20110008430Solid Pharmaceutical Dosage Form - A solid pharmaceutical dosage form providing improved oral bioavailability is disclosed for inhibitors of HIV protease. In particular, the dosage form comprises a solid dispersion of at least one HIV protease inhibitor and at least one pharmaceutically acceptable water-soluble polymer and at least one pharmaceutically acceptable surfactant, said pharmaceutically acceptable water-soluble polymer having a Tg of at least about 50° C. Preferably, the pharmaceutically acceptable surfactant has an HLB value of from about 4 to about 10.01-13-2011
