TRANSDERMAL THERAPY SYSTEM (TTS) FOR RELEASING AN ACTIVE AGENT INTO AN ORGANISM THROUGH THE SKIN AND METHOD FOR APPLYING SAID TRANSDERMAL THERAPY SYSTEM TO THE SKIN |
摘要 |
The inventive transdermal therapy system (TTS) for releasing an active agent into a human or an animal organism through the skin comprises a matrix (5) containing the active agent, with an adhesive active layer (2) which faces towards the skin and which can be covered with a detachable protective layer (11) before application, and a cover layer (1). Said cover layer (1) is impenetrable to the active agent and forms a barrier between the matrix (5) and the outside. The inventive system is characterised in that at the time of application, a part-section (6) of the surface of the active layer (2) of the matrix (5) which releases the active agent and faces towards the skin is covered by a barrier layer (3), said barrier layer being impenetrable to the active agent. |
