  • Patent number: 8105630
    Abstract: A composition containing an extremely poorly water-soluble drug and obtained by treating, with a supercritical fluid or subcritical fluid of carbon dioxide, a mixture comprising a porous silica material and the extremely poorly water-soluble drug; and its production process. The porous silica material has an average pore diameter in a range of from 1 to 20 nm, pores having diameters within ±40% of the average pore size account for at least 60% of a total pore volume of the porous silica material, and in X-ray diffractometry, the porous silica material has at least one peak at a position of diffraction angle (2?) corresponding to a d value of at least 1 nm. The composition according to the present invention, which contains the extremely poorly water-soluble drug, is excellent in the dissolution of the extremely poorly water-soluble drug.

  • Patent number: 8101207
    Abstract: A composition containing a very low water-soluble drug, which composition is produced by treating, with a supercritical or subcritical carbon dioxide fluid, a mixture containing a very low water-soluble drug and a porous material (exclusive of a porous silica material characterized in that the material has an average pore diameter of 1 to 20 nm, the total pore volume of the material that have a diameter falling within a range of ±40% of the average pore diameter account for 60% or more the volume of all the pores of the material, and, when subjected to X-ray diffractometry, the material exhibits one or more peaks at a diffraction angle (2?) corresponding to d of 1 nm or more); and a method for producing the composition. The very-low-water-soluble-drug-containing composition of the present invention ensures improved dissolution of the very low water-soluble drug.

  • Publication number: 20110159058
    Abstract: The film preparation of the present invention includes: a drug-containing intermediate layer containing loperamide hydrochloride, a terpene and a film-forming agent; and coating layers containing a film-forming agent and a plasticizer (but not a terpene) and laminated on both sides of the drug-containing intermediate layer. As a bitter taste derived from loperamide hydrochloride is thereby masked, uncomfortable sensation when taking the film preparation can be reduced. Furthermore, as this film preparation is rapidly dissolved (i.e., has a rapidly dissolving property) only with moisture in the oral cavity, it begins to work quickly and is very convenient when it is carried and taken.
