PROBLEM TO BE SOLVED: To provide a preparation for percutaneous absorption, which causes fewer skin irritation compared to conventional ones, shows good wettability and adaptability to the skin, shows a sufficient adhesion to the skin, contains a sufficient amount of physiologically active substances and shows good releasability of the physiologically active substances.SOLUTION: The preparation for percutaneous absorption is an adhesive skin patch wherein adhesive composition layers are formed on a support. The adhesive composition layers are obtained by mixing at least two polymeric materials, at least one of which is a polyether polymeric material containing a siloxane bond. At least one of the adhesive composition layers contains the physiologically active substances.COPYRIGHT: (C)2008,JPO&INPIT【課題】従来の経皮吸収製剤に比較して皮膚刺激性が小さく、皮膚への濡れ性、なじみが良好で、皮膚に対して十分な粘着力を持ち、十分な量の生理活性物質を含有させることが出来、かつ生理活性物質の放出性の良い経皮吸収製剤を提供することにある。【解決手段】支持体上に粘着剤組成物層が形成された皮膚貼付剤において、該粘着剤組成物層が少なくとも2種類以上の高分子材料を混合してなり、かつその少なくともひとつがシロキサン結合を含有するポリエーテル系高分子材料であって、該粘着剤組成物層の少なくとも1層が生理活性物質を含有することを特徴とする経皮吸収製剤。【選択図】 なし
