A percutaneously absorptive preparation is provided, which includes a drug reservoir layer, a drug reservoir layer-forming film, a cloth layer, an adhesive layer and optionally an impermeable support, wherein the drug reservoir layer is enclosed in the drug reservoir layer-forming film or enclosed by the drug reservoir layer-forming film and the support formed on the drug reservoir layer-forming film, the drug reservoir layer contains a drug except 2-tert-butylamino-1-(2-chloro-4-hydroxyphenyl)ethan-1-ol and a pharmacologically acceptable salt thereof, and the cloth layer and the adhesive layer are successively laminated on either side of the drug reservoir layer-forming film or on the side opposite from the support layer. The preparation of the present invention inhibits separation of the drug reservoir layer-forming film from the adhesive layer, glue remainder on the skin after peeling off, and deformation of the drug reservoir layer-forming film due to the solvent in the drug reservoir layer. In addition, the preparation of the present invention is superior in the percutaneous absorption of a drug.
本发明提供了一种经皮吸收制剂,它包括储药层、储药层形成膜、布层、粘合剂层和可选的防渗支架,其中储药层封闭在储药层形成膜中,或由储药层形成膜和形成在储药层形成膜上的支架封闭、储药层含有除 2-叔丁基
氨基-1-(2-
氯-
4-羟基苯基)-1-
乙醇及其药理上可接受的盐之外的药物,布层和粘合剂层依次层叠在储药层形成膜的两侧或与支撑层相对的一侧。本发明的制剂可抑制储药层成膜与粘合剂层的分离、剥离后皮肤上的胶
水残留以及储药层中的溶剂导致储药层成膜变形。此外,本发明的制剂在经皮吸收药物方面也更胜一筹。
