The possibility of administering drugs through the skin has been recognised for many years and has led to the development of a number of important therapeutic formulations, such as hormone replacement and nicotine replacement patches. Transdermal Drug Delivery is a comprehensive text that addresses all aspects of how to deliver drugs across the skin. Starting with a clear discussion of the theory behind this progressive technology, the text expands into the strategies used to deliver drugs effectively. An invaluable practical guide for the clinical delivery of drugs is included.
