Abstract
A method of increasing the delivery efficiency of an agent through a body surface by electrotransport is disclosed wherein the electrotransport current is applied for durations at a higher current density values followed by durations of lower current density values wherein the higher current density applications transform the body surface to an enhanced, non-transitory agent delivery efficiency state.
