Abstract The purpose of the present invention is to provide a patch preparation which uses a basic drug acid addition salt as a raw material and which has excellent skin permeability of the drug. This patch preparation is formed by providing an adhesive layer on one side of a support body, wherein the adhesive layer contains a basic drug, a fatty acid ionic liquid and a potassium salt and/or potassium ions. Said potassium salt and/or potassium ions may be generated in the adhesive by a reaction between the acid addition salt of the basic drug and a compound capable of generating potassium ions. An opioid analgesic is an example of the basic drug, and hydrochloride is an example of the acid addition salt. L'invention a pour objet de fournir une préparation pharmaceutique collante mettant en œuvre un sel d'addition d'acide de médicament basique en tant que matériau de départ, et présentant d'excellentes propriétés de pénétration de médicament à travers la peau. La préparation pharmaceutique collante de l'invention est constituée par agencement d'une couche d'adhésif sur une face d'un support, et contient un médicament basique, un liquide ionique à base d'acide gras, et un sel de potassium et/ou un ion potassium dans ladite couche d'adhésif. Le sel de potassium et/ou l'ion potassium est produit par une réaction entre un sel d'addition d'acide dudit médicament basique et un composé permettant la génération d'ions potassium, dans un adhésif. Un analgésique opioïde est un exemple de médicament basique, et un hydrochlorure est un exemple de sel d'addition d'acide. 本発明は、塩基性薬物酸付加塩を原料として用い、薬物の皮膚透過性に優れた貼付製剤を提供することを目的とする。 本発明の貼付製剤は、 支持体の片面に粘着剤層を設けてなる貼付製剤であって、 前記粘着剤層中に塩基性薬物、脂肪酸系イオン液体及びカリウム塩及び/又はカリウムイオンを含む。 該カリウム塩及び/又はカリウムイオンは、粘着剤中で、前記塩基性薬物の酸付加塩と、カリウムイオンを生成可能な化合物との反応により生じたものであり得る。 塩基性薬物としてはオピオイド系鎮痛剤が例示され、酸付加塩としては塩酸塩が例示される。
