ABSTRACT:
A composition comprises an agent to be delivered through a body surface and an electrotransport enhancer having a hydrophobic tail and a polar head of specific characteristics. An electrotransport delivery device is also provided having a reservoir comprising the agent to be delivered and the electrotransport enhancer of the invention. The electrotransport enhancers increase the electrotransport delivery rate of the agent through the surface while reducing the electrical resistance of the surface during electrotransport of the agent.
