Abstract
An electrode for use in an iontophoretic drug delivery having a substantially uniform distribution of current about the electrode. One such electrode includes a substrate, at least one first conductive layer of material disposed upon the substrate and at least one dielectric layer of material disposed upon at least a portion of the at least one conductive layer of material. The dielectric layer cooperates with the conductive layer of material to promote the substantially uniform distribution of current. Another such electrode includes a substrate, a conductive layer of material and a sacrificial layer of material.
