Abstract

A transdermal electrotransport fentanyl delivery system having relatively stable fentanyl flux. The system has a controller that controls a current through a donor reservoir wherein the current generally changes with time nonlinearly and nonexponentially to result in a relatively stable fentanyl flux.
