  • Patent number: 9101617
    Abstract: The present invention provides a novel base material for a dry solid dispersion, a solid dispersion containing the base material, and a composition containing the dispersion; the solid dispersion of the present invention, which contains a poorly soluble component with improved dissolvability, can be obtained by mixing a polyvinyl alcohol-based copolymer, as a base material for the dry solid dispersion, with a poorly soluble component, and then heating it.

  • Publication number: 20090304800
    Abstract: An object of the present invention is to provide a dry coating process that can produce a dry-coated preparation in a large amount. A large amount of dry-coated preparation can be produced more efficiently, than by prior-art processes, by a process in which a material containing core particles and a dry binder (lauric acid, myristic acid, or the like) is kneaded in a twin-screw kneader to produce dry binder particles in which the surfaces of the core particles are dry-coated with the dry binder. Further, a dry coating particle production process in which a material containing core particles, a dry binder, and a coating powder is kneaded in a twin-screw kneader can also produce a large amount of dry-coated preparation more efficiently than prior-art processes.
