Abstract
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 active agent; and a polymer complex layer disposed between the first compartment and the second compartment, the polymer complex being formed by a first hydrophilic polymer and a second hydrophilic polymer via hydrogen bonding. The polymer complex is electrically responsive and disintegrates when an electrical field is applied. The active agent and the diluent become mixed to form a transient solution or dispersion prior to administration of the active agent
