Abstract

The invention relates to systems formed from closed liquid-tight packaging and a preferably dimensionally stable aqueous composition which is sealed therein and which, upon activation, releases a liquid phase essentially composed of water in a time-delayed manner. The invention further relates to methods for manufacturing such systems and the use thereof during the production of self-decomposing transdermal therapeutic systems (TTS).
