An iontophoresis device includes: an active electrode element operable to provide an electrical potential; an inner active agent reservoir comprising : a first compartment having a diluent; a second compartment having an activ e agent; and a polymer complex layer disposed between the first compartment and the second compartment, the polymer complex being formed by a first hydr ophilic polymer and a second hydrophilic polymer via hydrogen bonding. The p olymer complex is electrically responsive and disintegrates when an electric al field is applied. The active agent and the diluent become mixed to form a transient solution or dispersion prior to administration of the active agen t.
