Abstract
An iontophoretic electrode device, method, and hydrophilic, hydrated gel insert for the electrode device all involve a preformed, shape-retaining, gel body preferably of disc formation having mutually opposite, parallel faces. An agar gel disc having an ionic drug diffused throughout is the preferred, iontophoretic gel body that is packaged and sold as such for insertion in a cup-like receptacle and securement to an electrode plate within the receptacle, so as to protrude free and clear therefrom for pressing against the skin of a medical patient.
