  • Publication number: 20180235876
    Abstract: A method is used in the production of a disintegrative particulate composition including three components consisting of a first disintegrator component having sedimentation volume in water of 4.0 cm3/g or more, and a second disintegrator component other than the first disintegrator component and an excipient. The method includes a first wet granulation step using any two of the three components, and a second wet granulation step using the granules obtained in the first wet granulation step and at least the component not used in the first wet granulation step; thus the disintegrative particulate composition is produced. Moreover, an orally disintegrating tablet contains a medicinal ingredient and the disintegrative particulate composition.

  • Publication number: 20160213619
    Abstract: An object of the present invention is to provide an orally disintegrating tablet having both an excellent tablet hardness and disintegrability even when the content of a medicinal ingredient is high. This invention relates to an orally disintegrating tablet comprising a medicinal ingredient having distribution coefficient (log P) in a range of from ?6.0 to 10.0 and a disintegrative particulate composition produced by granulation consisting of at least two stages, especially to said orally disintegrating tablet having tablet hardness of from 30 to 100 N, and disintegration time in water of from 10 to 30 sec.

  • Publication number: 20160136097
    Abstract: An object of the present invention is to provide an orally disintegrating tablet (ultrafast-disintegrating tablet) having an extremely high disintegrability (short disintegration time), and a high tablet hardness, and to provide a simple method for the production of said ultrafast-disintegrating tablet without such a complicated process as freeze-drying. This invention relates to an orally disintegrating tablet comprising a first disintegrator component of an acid-type carboxymethylcellulose, and having a tablet hardness of 10 N or more and a disintegration time in water of less than 15 seconds, a method for the production of said orally disintegrating tablet, and to a disintegrative particulate composition for use in said method.

  • Publication number: 20150045452
    Abstract: The present application provides an orally-disintegrating tablet having excellent tablet hardness and disintegrability. The present application further provides a method of producing a disintegrative particulate composition including three components consisting of a first disintegrator component of an acid-type carboxymethylcellulose, a second disintegrator component and an excipient. The method includes a first wet granulation step using any two of the three components, and a second wet granulation step using granules obtained in the first wet granulation step and the remaining one component of the three components not used in the first wet granulation step. The production method may further includes a crystalline cellulose as a fourth component or a third step of mixing a crystalline cellulose into granules obtained in the second wet granulation step. Disintegrative particulate compositions obtained by these methods are also disclosed.
