A system and method of electrotherapy for enhanced drug delivery, comprising an electrode patch and an electrotherapy apparatus providing electrical current onto the electrode patch. The electrode patch contains one or more active drug ingredients in a layer of conductive gel, and the electrotherapy apparatus provides electrical current onto the electrode patch for the enhanced drug delivery of active drug ingredients. The conductive gel is in contact with a human or animal body, and the electrode patch also includes a layer of conductive sheet, a supporting layer, and conductive connectors. The conductive gel has the viscosity allowing it to adhere to skin on a human or animal body. The active drug ingredients that can be delivered through the conductive gel include: lidocaine, capsaicin, menthol, camphor, methyl salicylate, trolamine salicylate, Arnica montana, Calendula officinalis, Hypericum perforatum, Symphytum officinale, cannabidiol (CBD) or any combination of these substances. The mass fraction of the active drug ingredients can vary from 0.001% to 30%. The electrotherapy device can be reused.
