Abstract
The present invention is an apparatus and method that maintains a constant drug delivery rate for an electrotransport delivery system, while the apparent transport efficiency of the system varies, by making adjustments to the output current of the system. More specifically, the constant drug delivery rate is maintained by the regulator of the electrotransport delivery system automatically adjusting the output current to compensate for the varying apparent transport efficiency.
