<p>In a iontophoretic treatment system an electrical current is applied (30) between a pair of electrodes and is periodically reversed at very low frequencies (31), substantially in the range of approximately 0.0027 Hz to approximately 10 Hz, to mitigate tissue damage, enable long term dosimetry with single and multiple drugs of any polarity and at higher concentrations. The system delivers treatment substances with large and/or small molecular size and weight and can be adjusted to control pH at the delivery site. <IMAGE></p> |
