  • Patent number: 8894621
    Abstract: The invention relates to a self-destructing transdermal therapeutic system (TTS), preferably in the form of a transdermal patch, that includes an active ingredient, an agent rendering the active ingredient useless, and a perforation mechanism. The perforation mechanism allows a mobile phase to reach the agent that is capable of rendering the active ingredient useless after removing the TTS after use. The agent then comes into contact with the active ingredient and destroys the active ingredient in the presence of the mobile phase.
