  • Patent number: 6696084
    Abstract: The present invention relates to a novel spray drying process for the preparation of pharmaceutical compositions containing small particles of phospholipid-stabilized fenofibrate. This invention also relates to spray dried powdered compositions prepared according to this process, and to dosage forms of fenofibrate (capsules, tablets, powders, granules, and dispersions) prepared from these powdered compositions. The powdered compositions and dosage forms are useful in the treatment of dyslipidemia and dyslipoproteinemia and have the advantage that they provide reduced in vivo variability in the bioavailability of fenofibrate active species among fed and fasted patients when administered orally.

  • Patent number: 6465016
    Abstract: Pharmaceutical compositions containing solid cyclic oligopeptide cyclosporine microparticles are prepared by applying energy input to solid cyclic oligopeptide cyclosporine in the presence of phospholipid and one or more non-ionic, anionic or cationic second surface modifiers. The microparticles consist essentially of a solid cyclic oligopeptide cyclosporine core coated with a combination of phospholipid and at least one second surface modifier. The combination of phospholipid and second surface modifier(s) provide volume-weighted mean particle size values of solid cyclic oligopeptide cyclosporine particles that are about 50% smaller than cyclic oligopeptide cyclosporine particles produced in the presence of the phospholipid and without the presence of the second surface modifier(s) using the same energy input.
