An object of the present invention is to provide an easy-to-take solid preparation preparation and easy-to-take, which is mainly characterized by simply performing an easy-to-take coating treatment with a gelling agent in a dry manner without going through a wet state. To provide functional solid preparations. The present invention directly applies a powder comprising a coating agent containing a gelling agent that exhibits slipperiness upon contact with water to the inner surface of the mortar, the upper lower end surface, and the lower upper end surface. A solid production method comprising a dry preparation method of an easily takeable solid preparation formed by coating a compression-molded core with the coating agent, including filling and integral compression molding, and a solid containing a water-soluble polymer used in the production method The present invention relates to a powder composition for coating a preparation.本発明の課題は、湿潤状態を経由することなく、乾式にて、ゲル化剤による易服用化コーティング処理を簡易に行うことを主な特徴とする、易服用性固形製剤の製造方法及び易服用性固形製剤等を提供すること。本発明は、臼内面、上杵下端面及び下杵上端面に、水に触れると滑り性を示すゲル化剤を含むコーティング剤から成る粉体のみを直接に適用した後、核用成形材料を充填して一体圧縮成形することを含む、圧縮成形された核を該コーティング剤で被覆して成る易服用性固形製剤の乾式製造方法、及び、該製造方法に用いる水溶性高分子を含む、固形製剤被覆用粉体組成物等に関する。
