ABSTRACT:
The invention relates to a transdermal therapeutic system (TTS), preferably in the form of a transdermal plaster, that contains an active substance and an agent which can destroy the active substance. The TTS further includes a means of bringing the active substance, e.g. buprenorphine, and the agent, e.g. potassium permanganate, into contact when the TTS is removed from the skin of the patient, thereby causing the active substance to be destroyed.
