  • Patent number: 10231929
    Abstract: A solid dispersion for achieving improved solubility and absorbability of a pharmaceutically active ingredient, which contains (1) an amorphous pharmaceutically active ingredient, (2) one or more substances selected from among methyl cellulose and organic acids and (3) an enteric base material. In cases where methyl cellulose is contained therein, the solid dispersion does not contain any water-soluble polymer other than methyl cellulose.
    Type: Grant

  • Publication number: 20140178477
    Abstract: The present invention provides a solid preparation formulation containing a poorly water-soluble agent having a low melting point, a saccharide, and a cellulose selected from a crystalline cellulose and a low-substituted hydroxypropylcellulose, in which the saccharide/cellulose weight ratio exceeds 2 and the cellulose content is not less than 5 wt %. This formulation provides a composition that can be produced with direct granulation, yet which delivers stability during production and storage.

  • Publication number: 20130273157
    Abstract: A orally disintegrating tablet is obtained by tableting fine granules showing controlled release of lansoprazole and an additive, which is capable of suppressing breakage of the fine granules during tableting, and can control the release of lansoprazole for a long time, and can maintain a therapeutically effective concentration for a prolonged time, and shows superior disintegration property in the oral cavity.

  • Publication number: 20090208584
    Abstract: The solid preparation of the present invention aims at providing a solid preparation superior in the stability during production and preservation even when a poorly water-soluble substance having a low melting point is contained in a large amount, and also superior in the disintegration property and release property of a poorly water-soluble substance having a low melting point, after oral administration, and is characterized by the following 1) to 3): 1) containing a poorly water-soluble substance having a low melting point, a saccharide, and a cellulose selected from a crystalline cellulose and a low-substituted hydroxypropylcellulose, 2) a saccharide/cellulose weight ratio exceeding 2, and 3) a cellulose content of not less than 5 wt %.
