  • Publication number: 20230165799
    Abstract: A dry granulation process using a twin-screw extruder for granulating a powder mixture which includes at least one active ingredient and at least one carrier. The process includes steps of kneading the powder mixture in the screw barrel of the twin-screw extruder at a barrel temperature below a melting point of the at least one active ingredient and a melting point or a glass transition temperature of the at least one carrier to provide a kneaded powder mixture, and extruding the kneaded powder mixture to form granules. Granules and tablets produced using the dry granulation process in the twin-screw extruder are also provided.

  • Patent number: 6858725
    Abstract: Granulation of microcrystalline cellulose with a granulating fluid consisting of water and a water-miscible, volatile, polar organic solvent yields porous granules which are comprised of particles that are larger than the ungranulated microcrystalline cellulose. This granulated microcrystalline cellulose is capable of cushioning controlled release particles and barrier coated particles from the compression forces used in tableting, thereby maintaining the physical integrity of the components of the tablet.

  • Publication number: 20040081701
    Abstract: The present invention provides a method for preparing a spray-dried, compressible granular formulation for preparing pharmaceutical tablets in which essentially water-insoluble, acidic, amphoteric, and basic pharmaceutically active agents are converted to more water-soluble salts which are granulated with hydrolyzed cellulose, drug-containing slurries, the resulting granulations, capsules containing granulations, and pharmaceutical tablets compressed from such granules. In these formulations there is employed from 1% to 85% by weight of the pharmaceutically active agent in its salt form, from 5% to 99% of hydrolyzed cellulose, based on the dry weight of the granulation, and optionally, conventional granulation and/or tableting additives such as surfactants, disintegrants, and antiadherents/flow aids. Said tablets have significantly increased dissolution of the pharmaceutically active agent at the pH of the gastrointestinal tract in comparison with the unconverted free pharmaceutically active agent.

  • Patent number: 6511681
    Abstract: A formulation of a sparingly water-soluble, crystalline pharmaceutically active agent wherein the active agent is converted to and stabilized in its amorphous form as a solid solution of a normally hydrophobic vehicle is described. The amorphous state is stabilized by the composition of the formulation, providing long shelf life of the improved composition. This stabilized formulation also provides increased solubility and bioavailability of the active agent. Solutions of the active agent are stabilized by the composition, preventing recrystallization and precipitation of the less soluble, crystalline form of the active agent from aqueous solutions thereof.
