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.
Claims24
A skin patch comprising:
- a support having an electrically charged surface resulting from the application to the support of an ionizing field;
- an adhesive disposed on the periphery of the support, the adhesive configured to adhere the patch to skin;
- and
- a preselected amount of an organic allergen, the organic allergen being in the form of individualized or agglomerated dry particles bound to the electrically charged surface through electrostatic forces.
