1. In combination, in a system for the iontophoretic topical delivery of a pharmaceutically active agent, said system comprising:

  • a. means for generating a substantially constant current pulsed DC output voltage;

    b. means for converting said output voltage into a double modulated output adjustable constant current waveform;

    c. contact means for containing and delivering said pharmaceutically active agent to a topical area of a patient in need of treatment, said contact means including at least two electrodes;

    d. means for directing said double modulated output waveform to said contact means;

    wherein said double modulated output waveform comprises a first waveform component ranging between 1 Hz and 300 GHz, a second waveform component ranging between 10 and 199,000 Hz, and a third waveform component ranging between 100 Hz and 300 GHz, and each waveform component is substantially time invariant and distinct from said other waveform components, said double modulated output waveform having a monopolar characteristic.
