The inventi on is characterised in that a) the non-steroidal antirheumatic agent has a free carboxyl group; b) the matrix containing the active agent consists of a polyacrylate adhesive which is cross-linked with multivalent metal ions and which has free carboxyl groups, and is free of hydroxyl groups; c) the matrix contains a fatty acid which serves as a plasticizer and a permeation accelerator; and d) the back layer consist s of a material which is elastic in at least one direction.
