More Information
Summary:The inventive system substantially comprises a two-phase adhesive layer that contains an active substance. An inner phase (2) that contains the active substance in dissolved form is embedded in the outer, vapor-impermeable phas e (3) in a dispersed form. Combined with an elastic backing layer (1), preferably a warp/weft-elastic fabric, a very thin matrix system is obtained that guarantees an excellent wear comfort and that optimally utilizes the occlusive effect for an increased absorption of the active substance via the skin.
