Transdermal therapeutic system based on polyacrylate-contact-bonding adhesives without functional groups

摘要

The invention relates to a transdermal therapeutic system (TTS) consisting of a rear layer, a protective layer and an active-substance-containing polymer layer. The polymer matrix comprises a polyacrylate which contains an extremely reduced number of functional groups. In one particular embodiment, the polyacrylate is free from hydroxyl groups and/or carboxyl groups.
