  • Patent number: 6475467
    Abstract: The use of solid, pharmaceutically acceptable salts of cromoglycic acid and/or nedocromil as carriers in a therapeutically and prophylactically inefficacious amount in suspension aerosol formulations of pharmaceutical active compounds improves the dispersion properties, increases the chemical and physical stability of moisture-sensitive active compounds, makes possible a more accurate dosage, in particular even of low-dose active compounds, and as a rule permits the abandonment of surface-active agents.

  • Patent number: 6395287
    Abstract: The present invention aims to provide a lotion stably maintaining maxacalcitol and having excellent percutaneous absorption. The present invention provides lotions comprising maxacalcitol as an active ingredient and a nonionic surfactant as an additive, as well as lotions which further contains a polyhydric alcohol and a solubilizer as additives besides a nonionic surfactant.

  • Patent number: 6380281
    Abstract: A distinctive graft copolymer is made by dissolving an unsaturated polyester resin in various vinyl monomers (methyl methacrylate, styrene, etc.). The monomer/unsaturated polyester solution is then miniemulsion polymerized to form a latex consisting of submicron particles of polymer with the polyester grafted onto the polymer backbone. The latex can be applied to a substrate, which on drying forms a polymeric film with good film properties. The latex can be used in a latex paint formulation in place of an acrylate, acetate or styrene-divinyl benzene latex. In this way it is possible to produce water-borne unsaturated polyester coatings which combine the film hardness properties of an unsaturated polyester coating with easy application and cleanup. The coating will beneficially lack organic solvent exposure of typical polyester coatings.

  • Patent number: 6375986
    Abstract: Disclosed are solid dose nanoparticulate compositions comprising a poorly soluble active agent, at least one polymeric surface stabilizer, and dioctyl sodium sulfosuccinate (DOSS). The solid dose compositions exhibit superior redispersibility of the nanoparticulate composition upon administration to a mammal, such as a human or animal. The invention also describes methods of making and using such compositions.

  • Patent number: 6369135
    Abstract: A distinctive graft copolymer is made by dissolving an alkyd resin in various vinyl monomers (methyl methacrylate, styrene, etc.). The monomer/alkyd solution is then miniemulsion polymerized to form a latex consisting of submicron particles of polymer with the alkyd grafted onto the polymer backbone. The latex can be applied to a substrate, which on drying forms a polymeric film with good film properties. The latex can be used in a latex paint formulation in place of an acrylate, acetate or styrene-divinyl benzene latex. In this way it is possible to produce water-borne alkyd coatings which combine the film hardness properties of an oil-based alkyd coating with easy application and cleanup. The coating will beneficially lack organic solvent exposure of typical standard latex coatings.

  • Patent number: 6358526
    Abstract: The present invention provides a method of making tablet compositions that are substantially free of excipients. The method includes forming a compactable granular mixture containing at least one compaction enhancing therapeutic compound, at least one other therapeutic compound that is different form the compaction enhancing therapeutic compound, and less than about 15 weight percent of a non-aesthetic excipient. The compactable granular mixture thus obtained is compressed to form a tablet composition. The present invention also provides tablet compositions produced by the methods of the present invention that are substantially free of excipients.
