Abstract
An electrotransport agent delivery device for delivering a therapeutic agent through a body surface, and a method for increasing agent delivery efficiency, is provided. The device includes a current controller which delivers a pulsating electrotransport current and peak current density I.sub.max, I.sub.max being greater than a critical current density level I.sub.c above which the body exhibits a non-transitory higher agent delivery efficiency. Methods for increasing electrotransport delivery efficiency (E) of an agent through a body surface by creation of a higher agent delivery efficiency state are also provided.
