The main object of the present invention is to provide a patch package structure including a patch containing a physiologically active ingredient and a package housing the patch, which is capable of stably retaining the physiologically active ingredient in the patch during preservation. This object can be achieved by employing the following constitution.To be specific, the present invention is a patch package structure including a patch 1 having an adhesive layer containing an organic liquid component, and a packaging member 51 housing the patch, wherein the packaging member 51 includes a first package 11, the first package 11 including an acrylonitrile resin layer 12, a moisture-absorbing layer 13 formed on the acrylonitrile resin layer 12, and a moisture impermeable layer 14 formed on the moisture-absorbing layer 13, and the acrylonitrile resin layer 12 is provided on the proximal side of the patch 1.
摘要:
[Object] An adhesive preparation containing donepezil is provided in which adhesive layer discoloration over time is inhibited.[Solution] The adhesive preparation containing donepezil has an adhesive layer containing donepezil and an acrylic adhesive on at least one side of a support, and a water content of the adhesive layer is 1000 ppm or more. The water content of the adhesive layer is preferably 8000 ppm or less and more preferably 7000 ppm or less.
