  • Publication number: 20120190667
    Abstract: A process for preparing solid dispersions of highly crystalline compounds. The highly crystalline or thermally labile therapeutic compounds are processed in an extruder in combination with a solubilizing agent and optionally a plasticizer. The resulting extrudate features the therapeutic compound in an amorphous state. Particularly useful as the solubilizing agents are surfactants such as poloxamers.

  • Publication number: 20100331387
    Abstract: Pharmaceutical compositions that include a poorly water-soluble therapeutic compound, an aqueous solvent, an chelator/antioxidant, a buffer or buffer component, and a bulking agent. The pharmaceutical compositions can be orally ingested or administered parenterally. The pharmaceutical compositions can further be lyophilized to form a pharmaceutically acceptable cake that can be administered orally, e.g., as a solid oral dosage form; or reconstituted and administered parenterally, e.g. as a single i.v. bolus or iv infusion, or administered orally, e.g. as a drink solution.
