Abstract
A patch comprises a support having electrostatic properties. The periphery of the support is coated with an adhesive material, and all or part of the non-adhesive surface of the support is directly covered with at least one biologically active substance in the form of particles. The particles remain in contact with the non-adhesive part of the support as a result of the electrostatic forces.
