PROBLEM TO BE SOLVED: To provide a diclofenac sodium-containing aqueous plaster which does not show crystal preciptation into a plaster ever after a long storage and has an excellent initial rate of chemical release while sustaining this chemical release.SOLUTION: The diclofenac sodium-containing aqueous plaster includes a homogeneous diclofenac sodium mixed solution obtained by mixing crotamiton and diclofenac sodium at a mixing ratio of crotamiton/diclofenac sodium of &le8.0 and a mixing ratio of (water+crotamiton)/diclofenac sodium within a range of 3.0-20.0.COPYRIGHT: (C)2011,JPO&INPIT【課題】ジクロフェナクナトリウム含有水性貼付剤の提供。【解決手段】ジクロフェナクナトリウム含有水性貼付剤において、クロタミトン/ジクロフェナクナトリウムの配合比率が8.0以下で、かつ(水+クロタミトン)/ジクロフェナクナトリウムの配合比率が3.0~20.0の範囲で混合して得られるジクロフェナクナトリウムの均一な混合溶液を配合してなる該ジクロフェナクナトリウム含有水性貼付剤。【選択図】なし
