  • Publication number: 20220158190
    Abstract: An object of the present invention is to provide a slurry having a viscosity that gives a good coating property at a temperature near room temperature (for example, at 25° C.), exhibiting a suppressed decrease in the viscosity during heating to a high temperature drying condition (for example, to 80° C.), and thus making its coating film resistant to collapse in shape. A slurry according to an embodiment of the present invention contains at least a binder and a fibrous material, wherein a ratio of a lowest viscosity up to 80° C. (lowest viscosity during heating to 80° C.) to a viscosity at 25° C. (viscosity at 25° C.), (lowest viscosity during heating to 80° C.)/(viscosity at 25° C.), is 0.12 or greater. The slurry according to the present invention preferably further contains an active material.

  • Patent number: 10864165
    Abstract: An object of the present invention is to provide an orally disintegrating tablet (super-rapid disintegrating tablet) that is heavy and relatively thin, and has an extremely high disintegrability (short disintegration time), and a high tablet hardness, and to provide a simple method for the production of said super-rapid disintegrating tablet without such a complicated process as freeze-drying. This invention relates to an orally disintegrating tablet having a specific surface area of from 1.50 to 4.00 mm2/mg and a weight of from 100 to 300 mg, particularly having a disintegration time in water of 7 seconds or less and an oral disintegration time of 6 seconds or less, a method for the production of said orally disintegrating tablet, and to a disintegrative particulate composition for use in said method.
