  • Patent number: 10166197
    Abstract: Solid dosage forms containing nanoparticles are prepared where sugar esters serve as nanoparticle stabilizers that prevent agglomeration of nanoparticles during preparation of the solid dosage form and allow for restoration of the original nanoparticle size of the nanoparticles upon redispersion of the solid dosage form in aqueous media.
    Type: Grant
    Filed: February 12, 2016
    Date of Patent: January 1, 2019
    Assignee: St. John's University
    Inventors: Hetalben N. Prajapati, Abu T. M. Serajuddin

  • Publication number: 20140350027
    Abstract: Sustained release pharmaceutical compositions that contain imatinib or a pharmaceutically acceptable salt thereof. The pharmaceutical compositions further contain a release retardant, for example a water soluble, a water swellable and/or a water insoluble polymer. The present invention also features a particularly useful process of making such sustained release pharmaceutical compositions by using an extruder.

  • Publication number: 20120077879
    Abstract: A process for preparing solid dosage forms that contain poorly compressible therapeutic compound. The process, for example, provides for the inventive use of an extruder, especially a twin screw extruder, to melt granulate a therapeutic compound(s) with a granulation excipient.
    Type: Application

  • Publication number: 20110037185
    Abstract: A process for manufacturing solid oral dosage forms in an equipment train that comprises multiple pieces of apparatus designed for unit operations, such as blending, extruding, cooling, milling and finishing. The equipment in the equipment train allow for the transfer of raw materials and intermediate-processed materials from one apparatus to the next using transfer means, for example, gravity, vacuum, belts, and the like.
