A reservoir means, in at least one of said electrode elements of said applicator, containing said medicament; and a circuit, including a power source, for supplying electric power to said electrodes and such reservoir means. Suitable cover means partially enclosed at least said reservoir means, and adhesive means affixes the applicator to the skin, so as to complete an electrical circuit through the skin when the applicator is affixed thereto, thus creating at least one physico/chemical mass transfer phenomenon which causes said medicament to migrate through the skin. | |
