<p>A method and apparatus are disclose for transdermal iontophoretic delivery of ionic species, such as a drug in ionic form, in which therapeutic, electrical pulses having controlled, distinctive, dual-segment waveform characteristics are applied which facilitate more efficient drug administration throughout each pulse. The therapeutic pulses are generated at a predetermined frequency and have a predetermined pulse width. A first pulse segment and a second pulse segment comprise each dual-segment, therapeutic pulse. The electrical attributes of each pulse segment, including amplitude and duration, are controlled to produce the desired, pulsed output waveform.</p> |
