Abstract
An electrotransport drug-containing composition is provided. The composition includes a drug to be delivered through a body surface (eg, skin) of a patient, and a permeation enhancer which is solid or semisolid at temperatures typically encountered during storage of pharmaceuticals (eg, temperatures up to at least about 25.degree. C.). The composition of the invention may be applied from a device 10 suitable for electrotransport delivery. A method for increasing electrotransport agent delivery rate and reducing body surface resistance relies on applying the composition of the invention to the body surface, and applying an electric current through the composition and the body surface.
