Abstract

An electrotransport device (10) for delivering therapeutic agents includes an adjustable voltage boost multiple controller (100, 200) for boosting the voltage from a power source (102, 202) to a working voltage V w having a value just sufficient to provide the desired therapeutic current level I1 through the electrodes (108, 112), at least one of which contains the therapeutic agent to be delivered.
Therapeutic agents to be delivered according to the present invention include fentanyl and other agents.
