  • Patent number: 8841303
    Abstract: The invention provides a dosage form, comprising a melt-processed mixture of (a) a pharmaceutically effective amount of imatinib or a salt thereof, (b) at least one polymeric binder, and (c) at least one pharmaceutically acceptable non-ionic surfactant. The invention provides imatinib dosage forms with high drug loading which can be prepared in a simple and efficient manner, imatinib dosage forms from which the active principle is released in an essentially pH-independent fashion, and extended release imatinib dosage forms.

  • Patent number: 8337733
    Abstract: A description is given of a process for the preparation of a pharmaceutical composition of a macrolide antibiotic in essentially noncrystalline form, in which the macrolide antibiotic, a water-swellable polymer and a proton donor are blended in an extruder in the presence of water and forced through a die, the ratio by weight of the sum of macrolide antibiotic, water-swellable polymer and proton donor to water being at least 1:1. The macrolide antibiotic is preferably clarithromycin and the water-swellable polymer is preferably chosen from crosslinked polyvinylpyrrolidone, crosslinked sodium carboxymethylcellulose and crosslinked polyacrylic acid.

  • 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: 20090050262
    Abstract: Disclosed is a method for producing dosing molds, according to which two separating films (7) are contacted with each other in a defined area, an active substance-containing melt is introduced between the separating films (7) such that a pocket for receiving a portion of the melt is embodied in at least one of the separating films, and the separating films (7) are separated from each other in order to eject the portion. Preferably, a method is disclosed in which the separating films (7) are contacted with each other in the gap of two molding rolls (2, 3) which rotate in opposite directions and are provided with opposite recesses (4, 5) on the surface thereof, and into which the separating films (7) can be pressed when the active substance-containing melt is introduced so as to form pockets. The separating films (7) make it possible to avoid a direct contact between the melt and the rolls (4,5) and thus prevent the melt from adhering to the roll (2, 3).
