  • Tablet quickly disintegrating in oral cavity
    Patent number: 8647668
    Abstract: The present invention provides rapid disintegrating tablets in oral cavity having a shortened disintegration time in oral cavity as well as a sufficient hardness compared to rapid disintegrating tablets of the prior art. The above objective is solved by a composition in which the inorganic excipient and the disintegrating agent are dispersed in the complex particles consisting of mannitol and other saccharide(s) in a specific ratio, and rapid disintegrating tablets in oral cavity obtained by direct compression of the composition.
    Type: Grant
    Filed: October 14, 2004
    Date of Patent: February 11, 2014
    Assignee: Fuji Chemical Industry Co., Ltd.
