摘要

The invention relates to a transdermal therapeutic system (TTS) for delivering pharmaceutical active ingredients, comprising a cover layer (7) and at least one active-ingredient-containing carrier material (1), wherein at least one retaining element (6a-6d) is located between the active-ingredient-containing carrier material and the cover layer, by means of which retaining element the active-ingredient-containing carrier material is fixed on the cover layer. The invention further relates to a method for fastening an active-ingredient-containing carrier material to a cover layer of a TTS in the presence of hook-and-loop strip segments and the use of a hook-and-loop strip in a method for the transdermal or iontophoretic administration of pharmaceutical or therapeutic active ingredients to patients.
