To provide a tablet in which an occurrence of disintegration delay in the oral cavity or gastrointestinal tract is suppressed.SOLUTION: The disintegration delay suppression coat powder of the present invention is a disintegration delay suppression coat powder which is coated with an edible coating material, in which an occurrence of disintegration delay is suppressed by the coating, and which has a feature that surface of disintegration delay causing powder as a unit of the coating is individually coated with the edible coating material. In addition, the disintegration delay suppression method for a tablet of the present invention is a disintegration delay suppression method for a tablet containing water-soluble disintegration delay causing powder and "an excipient powder having a water solubility lower than that of the disintegration delay causing powder but having a hydrophilicity", and has a feature that by coating the surface of the disintegration delay causing powder with the edible coating material individually, when the tablet contact to water, generation of "gel film or highly viscous liquid film" is inhibited, which is generated near surface of the tablet with "the disintegration delay causing powder existing near the surface of the tablet" and the water so that the water is allowed to easily enter the tablet inside.SELECTED DRAWING: Figure 5【課題】口腔内や胃腸内での崩壊遅延の発生が抑制された、錠剤を提供すること。【解決手段】本発明の崩壊遅延抑制被覆粉末は、可食性被覆材によって被覆されており、該被覆によって崩壊遅延の発生が抑制されている崩壊遅延抑制被覆粉末であって、被覆の単位である崩壊遅延惹起粉末の表面が個々に該可食性被覆材で被覆されていることを特徴とする。また、本発明の錠剤の崩壊遅延抑制方法は、水溶性の崩壊遅延惹起粉末、及び、「該崩壊遅延惹起粉末より水溶性は低いが水親和性がある賦形剤粉末」を含有する錠剤の崩壊遅延抑制方法であって、該崩壊遅延惹起粉末の表面を、個々に可食性被覆材で被覆することによって、該錠剤が水と接触したときに、「該錠剤の表面近傍に存在する該崩壊遅延惹起粉末」と該水とで該錠剤の表面近傍に形成される「ゲル状膜又は高粘性液体膜」の形成を阻害して、該錠剤の内部まで、水が進入し易くすることを特徴とする。【選択図】図５
