Abstract
Packaged patch () according to the invention comprises patch () situated in space () inside patch package () composed of laminated packaging material (), and its edges are sealed. Laminated packaging material () comprises hygroscopic material layer () made of LDPE containing 20–40 wt % of an inorganic filler, situated between moisture-permeable material layer () made of LDPE and having a moisture permeability of 40–120 g/m/day and a screen material layer which blocks penetration of moisture, etc. and is composed of HDPE layer () and aluminum foil (). The saturation hygroscopicity of laminated packaging material () is 2–30 g/munder atmosphere conditions with a temperature of 25° C. and a relative humidity of 75%. This construction sufficiently reduces the effect of moisture on a drug in patch () and allows patch () to be held in a stable state for prolonged periods, while also improving the economy and handleability of patch package ().
