Uv stable transdermal therapeutic plaster |
摘要 |
The invention relates to a UV stable transdermal therapeutic system (TTS) consisting of a back layer, at least one matrix containing an active substance and, optionally, a withdrawal film and an UV-radiation absorber. An adhesive layer containing said UV-radiation absorber is arranged between the back layer and the matrix containing an active substance which is distant as much as possible from a surface, a separation layer is arranged between the adhesive layer containing said UV-radiation absorber and the matrix containing an active substance, which is as remote as possible from the surface which is impermeable to the active substance and UV radiation absorber. The inventive transdermal therapeutic system exhibits a high stability and is devoid of inconveniences of existing TTS containing a light-sensitive substance.
