PROBLEM TO BE SOLVED: To provide an oral quickly-disintegrating tablet that can be produced by a simple process with a simple production device, quickly disintegrates in an oral cavity, and has moderate moldability enough for practical use, a method for producing the same, and a granule that serves as constitutional materials for the oral quickly-disintegrating tablet.SOLUTION: A composition for oral quickly-disintegrating tablets contains at least one excipient selected from the group consisting of saccharides and sugar alcohols, and tannic acid. The composition is obtained by mixing and drying the raw materials using tannic acid in a dissolved state.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】簡単な製造装置を用いて簡単な工程で製造でき、且つ口腔内で速やかな崩壊性を有するとともに、実用に耐える適度な成型性を有する口腔内速崩壊性錠剤、その製造方法、及びその口腔内速崩壊性錠剤の構成材料となる造粒物を提供する。【解決手段】糖類、及び糖アルコール類からなる群より選ばれる少なくとも1種の賦形剤、並びにタンニン酸を含む口腔内速崩壊性錠剤用組成物であって、溶解状態のタンニン酸を用いて各原料を混合し、乾燥することにより得られる、口腔内速崩壊性錠剤用組成物。【選択図】なし
