PROCÉDÉ DE PRODUCTION D'UNE COMPOSITION DE PARTICULES DÉLITANTES COMPRENANT DE LA CARBOXYMÉTHYLCELLULOSE DE TYPE ACIDE, COMPOSITION DE PARTICULES DÉLITANTES COMPRENANT DE LA CARBOXYMÉTHYLCELLULOSE DE TYPE ACIDE, ET COMPRIMÉ À DISSOLUTION ORALE CONTENANT UNE COMPOSITION DE PARTICULES DÉLITANTES COMPRENANT DE LA CARBOXYMÉTHYLCELLULOSE DE TYPE ACIDE
An object of the present application is to provide an orally-disintegrating tablet having excellent tablet hardness and disintegrability and a disintegrative particulate composition by which the orally-disintegrating tablet can be obtained with a relatively low tablet compression force and which can provide excellent moldability, as well as a method of producing the same, etc. The present application relates to 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 including 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； a production method further including a crystalline cellulose as a fourth component； a production method including a third step of mixing a crystalline cellulose into granules obtained in the second wet granulation step； disintegrative particulate compositions obtained by these methods, etc.
