Abstract
A device and method are provided that minimize the changes in flux encountered during iontophoresis and reduce inter-subject variability. For drug delivery, the active agent to be delivered is administered in conjunction with at least one background ion having a hindrance factor that changes at a faster rate than the hindrance factor of the active agent when an electrical current is applied. For analyte extraction, the extraction reservoir contains at least one background ion having a hindrance factor that changes at a faster rate than the hindrance factor of the background ions of the analyte in the tissue when an electrical current is applied.
