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.
