Abstract:
1. A method for evaluating iontophoretic delivery devices, the method comprising: applying at least a first test signal to an iontophoresis delivery device being evaluated; measuring at least one resistive or capacitive response of the iontophoresis delivery device being evaluated to at least the first test signal; comparing at least a first value indicative of the measured at least one resistive or capacitive response of the iontophoresis delivery device to one or more reference data sets indicative of at least one resistive or capacitive response of at least one reference iontophoresis delivery device; and determining whether the iontophoresis delivery device being evaluated meets an acceptance criteria based at least in part on the comparison, wherein applying at least a first test signal to an iontophoresis delivery device being evaluated includes applying an alternating current to the iontophoretic delivery device.
