Despite advances in the development of new drugs, a drug may never reach
the target organ, or it may be difficult to achieve the necessary level
of drug in the body. Large doses can result in serious side effects and
can harm normal, as well as diseased, cells and organs, and for this
reason it is vital that controlled release and the targeting of delivery
systems must evolve in parallel to drug research. Chemical Aspects of
Drug Delivery Systems reflects the modern challenge to devise effective
drug delivery and targeting systems, giving particular emphasis to
recent innovations in the field. Delivery systems described include
carbohydrate derivatives, novel nonionic surfactant vesicles and various
polymers, including polyacrylates and aqueous shellac solutions, as well
as hydrogels. In addition, many of the key issues, such as the
understanding of biosystems and targets and the development of materials
to provide the deserved carrier and excipient properties for controlled,
targeted drug delivery, are considered in depth. This book will be of
equal interest to undergraduate, graduate, researcher and those in the
pharmaceutical industries, and it complements two previous RSC Special
Publications, Encapsulation and Controlled Release and Excipients and
Delivery Systems for Pharmaceutical Formulations.
