Abstract
An ionic substance is mixed with a polar, non-ionic adhesive to form an electrode for use in the iontophoretic introduction of the ionic substance into a body. The electrode may be formed as a sheet of the mixture of a size and shape suitable for attachment to the electrode plate of an iontophoretic current generator. The mixture may be incorporated in an electrode as a means for holding the ionic substance, a means for attaching the electrode to the body, a means for attaching the iontophoretic current generator to the body, or a means for conducting the ionic current into the body. The electrode may also be employed in combination with an electrical stimulator to provide for simultaneous electrical stimulation and iontophoretic drug administration to the body.
