  • Publication number: 20180255008
    Abstract: Communication program code is communication program code incorporated into an application and continuously displays a startup button on an application screen, operates as a function of the application when the startup button is operated, and allows a talk between a user and a developer. A communication function allows the developer and the user to talk in real time, and hence the user of the application can easily give feedback, such as report of usability and problems, to the developer in real time.

  • Patent number: 9381248
    Abstract: A coating agent for a pharmaceutical solid preparation imparts an unpackaged pharmaceutical solid preparation with excellent barrier properties equivalent to those of a PTP sheet without affecting the disintegration properties of the pharmaceutical solid preparation. The coating agent for a pharmaceutical solid preparation includes a polyethylene glycol having an average molecular weight of 950 to 25,000 and a swelling clay, wherein the mass ratio of the polyethylene glycol and the swelling clay is 2:8 to 6:4.

  • Patent number: 8980320
    Abstract: A film coating agent for a solid formulation includes a water-soluble cellulose derivative, swelling clay, a cationic surfactant, and a fatty acid, wherein mass ratio of the swelling clay to the water-soluble cellulose derivative is 2:8 to 8:2, and content of the cationic surfactant is not less than 0.5 equivalents and not more than 3.0 equivalents relative to a cation exchange equivalent of the swelling clay.
    Type: Grant

  • Patent number: 8920818
    Abstract: A coating material for a solid formulation is capable of stably retaining the effective ingredient in the solid formulation for a prolonged period even in unpacked condition in such a manner that the solid formulation can be used in a single-dose formulation. The coating material for a solid formulation includes a high hydrogen-bonding resin and a swelling clay and, when coated on a solid formulation and dried, forms a coating film in which the laminated structures of the aforementioned swelling clay are oriented planarly and dispersed in a network fashion.

  • Patent number: 8658208
    Abstract: A montelukast-containing coated solid preparation can be applied to one-dose package, wherein the humidity stability of montelukast or a pharmacologically acceptable salt thereof contained therein is maintained even when the preparation is unpacked. A coated solid preparation contains as an active ingredient montelukast or a pharmacologically acceptable salt thereof and is coated with a coating layer comprising polyvinyl alcohol and swelling clay, wherein the mass ratio of the above-described polyvinyl alcohol to the above-described swelling clay in the above-described coating layer is 8:2 to 3:7.
