Abstract:
The invention relates to a transdermal therapeutic system (TTS) that is essentially composed of two compartments and that is provided with activatable oversaturation and controlled permeation promotion. The invention more particularly relates to a TTS, wherein an oversaturated active ingredient solution is produced in an active-substance-containing polymer matrix when the system is applied to the skin, caused by the controlled supply of one or several substances promoting permeation of the pharmaceutical active ingredient; the two compartments which make up the inventive transdermal therapeutic system; and the production of said transdermal therapeutic system from the two compartments.
