Abstract
Compositions, devices, and methods for transdermal administration of a drug are disclosed using a novel permeation enhancer mixture comprising a monoglyceride and ethyl palmitate. The monoglyceride/ethyl palmitate permeation enhancer is a potent permeation enhancer and provides stable systems which are more readily characterized. Additionally, ethyl palmitate cosolvent systems are more readily processed at manufacturing conditions thus providing further advantages over other cosolvents.
