  • Publication number: 20110182891
    Abstract: A pharmaceutical dosage form comprises a solid dispersion product of at least one active ingredient dispersed in a polymeric binder composition, the polymeric carrier composition comprising a) a vinylpyrrolidone homopolymer, wherein at least 95% by weight of the vinylpyrrolidone homopolymer has a molecular weight distribution within the range of from 1000 to 13 000; and b) a vinylpyrrolidone copolymer having a weight-average molecular weight of from 5000 to 1 500 000. The dosage form is preferably prepared by a melt extrusion process. The polymeric carrier composition exhibits a high drug dissolution power and allows a reduction of the viscosity of the melt without deteriorating the mechanical properties and storage stability of the dosage form.

  • Publication number: 20100297194
    Abstract: 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.

  • Publication number: 20090012184
    Abstract: 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.
