Transdermal therapeutic system comprising an adhesive layer method for siliconizing the back layer or the system and use of said back layer

摘要

The invention relates to a transdermal therapeutic system which comprises a backing layer, an adhesive layer, a polymer layer and a removable protective layer. The adhesive layer is an organosiloxane layer and is anchored in the backing layer by siliconization.

主权项

1. A transdermal therapeutic system comprising in spatial order
a) a siliconized backing layer, b) a polymer layer comprising a silicone adhesive consisting of polysiloxane or polysiloxane mixtures and microreservoirs containing at least one active ingredient, and c) a detachable protective layer in contact with the polymer layer, wherein said siliconized backing layer (a) comprises a backing layer coated with a siliconized adhesive that is firmly anchored to the backing layer, adheres to the polymer layer (b), and is formed from organopolysiloxanes containing vinyl groups and organopolysiloxanes containing Si—H groups.
