Abstract
A transdermal therapeutic system with a system support, at least one advancing element which is embedded into the system support, and at least one active ingredient reservoir which can be elastically deformed at least in some regions and which is embedded into the advancing element. On the application side of the transdermal therapeutic system, the system support surrounds the advancing element, and the advancing element surrounds the active ingredient reservoir. The advancing element comprises a swelling body which can be expanded by means of a liquid intake. The system support is designed to be rigid at least in some regions. A transdermal therapeutic system is developed which enhances the effect of the advancing element.
