  • Publication number: 20040209816
    Abstract: Methods and compositions for treating diabetes mellitus in a patient in need thereof are provided. The methods include administering to a patient a composition providing a gastrin/CCK receptor ligand, e.g., a gastrin, and/or an epidermal growth factor (EGF) receptor ligand, e.g., TGF-&agr;, in an amount sufficient to effect differentiation of pancreatic islet precursor cells to mature insulin-secreting cells. The composition can be administered systemically or expressed in situ by cells transgenically supplemented with one or both of a gastrin/CCK receptor ligand gene, e.g., a preprogastrin peptide precursor gene and an EGF receptor ligand gene, e.g., a TGF-&agr; gene. The methods also include transplanting into a patient cultured pancreatic islets in which mature insulin-secreting beta cells are proliferated by exposure to a gastrin/CCK receptor ligand and an EGF receptor ligand.

  • Publication number: 20040086571
    Abstract: This invention discloses an orally administered pharmaceutical composition for the treatment of elevated levels of cholesterol and related conditions comprising a statin and fenofibrate in the form of microparticles of solid fenofibrate that are stabilized by phospholipid as a surface active substance, wherein a therapeutically effective amount of the composition provides the statin and a quantity of fenofibrate to a fasted human patient that is greater than 80% of the quantity of fenofibrate provided by the same amount of the composition when administered to the same patient who has been fed a high fat meal.

  • 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.

  • Publication number: 20030206949
    Abstract: Rapidly dispersing solid dry therapeutic dosage form comprised of a water insoluble compound existing as a nanometer or micrometer particulate solid which is surface stabilized by the presence of at least one phospholipid, the particulate solid being dispersed throughout a bulking matrix. When the dosage form is introduced into an aqueous environment the bulking matrix is substantially completely dissolves within less than 2 minutes thereby releasing the water insoluble particulate solid in an unaggregated and/or unagglomerated state. The matrix is composed of a water insoluble substance or therapeutically useful water insoluble or poorly water soluble compound, a phospholipid and optionally also at least one non-ionic, anionic, cationic, or amphipathic surfactant, together with a matrix or bulking agent and if needed a release agent. The volume weighted mean particle size of the water insoluble particle is 5 micrometers or less.

  • Publication number: 20030180367
    Abstract: The invention provides a composition comprising microparticles of a water-insoluble or poorly soluble compound, at least one phospholipid, and at least one surfactant, produced by applying an energy to a mixture comprising particles of the compound, the at least one phospholipid, and the at least one surfactant so as to obtain the microparticles. The invention also provides a process for preparing microparticles of a water-insoluble or poorly soluble compound. The process includes mixing particles of a water-insoluble or poorly soluble compound with at least one phospholipid and at least surfactant to form a mixture and applying energy to the mixture sufficient to produce microparticles of the compound. The methods of the invention allow for the production of microparticles smaller than particles produced through previously known methods and the microparticles exhibit advantageous properties including remarkable resistance to particle size growth during storage.

  • 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.
