A transdermal therapeutic system which is composed of layers exhibits an electrically insulating backing layer (1) being impermeable to active substances, and two galvanic elements which are positioned in separation from each other. The skin-facing electrodes of the galvanic elements have layers thereon consisting of a liquid absorbing material becoming ionically conductive after liquid admission. The layer of at least one of the dermad electrodes comprises a pharmaceutical active substance.

A therapeutic system for carrying out transdermal iontophoretic therapies with a flexible, laminated layered structure, comprising a backing layer (1) which is impermeable to active substances as well as two sheet-like galvanic elements (3,4) having skin-facing electrodes, positioned separately from each other and connected in series via an electrically conductive connecting layer (2), which galvanic elements are positioned in reversed arrangement of anode and cathode the same distance from a surface of the backing layer (1), the skin-facing electrodes of said galvanic elements having ionically conductive layers (6,7) thereon made of a material which absorbs moisture and, after absorption of moisture becomes ionically conductive, an ionically conductive layer (6,7) on at least one of the skin-facing electrodes containing a pharmaceutically active substance, any chemicals in any layer, being in thermally dried condition.
