Abstract:
A substance release device comprising at least 3% by weight of a styrene-ethylene-propylene-styrene (â€œSEPSâ€ ) block copolymer, additional polymers based on block copolymers having at least one hard phase (A) based on styrene or derivatives thereof and at least one soft phase (B) selected from the group consisting of ethylene, butylenes, propylene, isoprene, butadiene and mixtures thereof constructed on the basis of diblock (A-B) and/or triblock (ABA) having less than 80% by weight diblock copolymers and at least one locally or systemically active substance which does not have a hyperaemic action and is selected from the group consisting of antimycotics, antiseptics, nonsteroidal antiheumatics, antipuritics, local anaesthetics, antipsonatics and keratolytics wherein the copolymer is foamed and has a glass transition temperature of less than 15Â° C. at a frequency of 0.1 rad/s and is in the form of an adhesive composition and the active is dispersed in the device.
