Abstract (en)

[origin: EP1095650A1] The invention relates to a delivery system for active ingredients which comprises a swellable phase defining at least one void. In this void an active ingredient may be present. The active ingredient may be substantially enclosed by the swellable phase, optionally with a degradable layer present between the gel phase and the active ingredient. The invention further relates to a method for providing such delivery systems, a method for non-medical administration of active ingredients, as well as to the use of a swellable phase in controlled release systems.
