Abstract: The invention relates to a transdermal therapeutic system comprising a surface layer which is impervious with respect to an active ingredient; a self-adherent matrix layer or a plurality of matrix layers, wherein the exposed matrix layer is, at least self-adherent when the system is applied. Said system also comrises a pull-off protective coating, whereby the matrix layer(s) contains one or more active ingredients and/or one or more biologically active substances and highly dispersed silicon dioxide. Said system contains silicon dioxide in order to increase skin permeation.
