PROBLEM TO BE SOLVED: To provide a dialysis agent produced at a low cost which contains at least calcium chloride as an electrolyte composition, each of the contained components of which is charged in a vessel as a single solid component, which is suppressed in solidification and coagulation of medicinal substance in the vessel.SOLUTION: A dialysis agent contains an electrolyte composition containing at least calcium chloride, and a pH adjuster. The ratio of a water removal amount of the calcium chloride and a water content of the entire dialysis agent is not less than 2% to less than 163%. The water content of the calcium chloride is in the range of 1%-22%. Each of the contained components is charged in a vessel as a single solid component.COPYRIGHT: (C)2015,JPO&INPIT【課題】電解質成分として少なくとも塩化カルシウムを含み、各含有成分が単一の固体成分として容器に充填された透析用剤において、薬剤の固結、凝集が抑制され、低コストで得られる透析用剤を提供する。【解決手段】少なくとも塩化カルシウムを含む電解質成分と、pH調整剤とを含有し、塩化カルシウムの除水量と透析用剤全体の含水量との比率が、163%未満2%以上であり、塩化カルシウムの水分含有率が1%~22%の範囲であり、各含有成分が単一の固体成分として容器に充填されている透析用剤である。【選択図】なし
