Skin, once thought to be an impenetrable barrier, is an extremely active organ capable of interacting with its environment. Advancements in science combined with the need for diverse drug delivery modalities have introduced a variety of transdermal and intradermal products for existing drugs at a fraction of the cost of new drug development. Commer

This research book covers the major aspects relating to the use of novel delivery systems in enhancing both transdermal and intradermal drug delivery. It provides a review of transdermal and intradermal drug delivery, including the history of the field and the various methods employed to produce delivery systems from different materials such as device design, construction and evaluation, so as to provide a sound background to the use of novel systems in enhanced delivery applications. Furthermore, it presents in-depth analyses of recent developments in this exponentially growing field, with a focus on microneedle arrays, needle-free injections, nanoparticulate systems and peptide-carrier-type systems. It also covers conventional physical enhancement strategies, such as tape-stripping, sonophoresis, iontophoresis, electroporation and thermal/suction/laser ablation Discussions about the penetration of the stratum corneum by the various novel strategies highlight the importance of the application method. Comprehensive and critical reviews of transdermal and intradermal delivery research using such systems focus on the outcomes of in vivoanimal and human studies. The book includes laboratory, clinical and commercial case studies featuring safety and patient acceptability studies carried out to date, and depicts a growing area for use of these novel systems is in intradermal vaccine delivery. The final chapters review recent patents in this field and describe the work ongoing in industry.

Microneedles can be used for delivery of a wide range of drug substances for practically any medical condition and present a real opportunity for vaccines and medicines that are unsuitable for oral administration or conventional patch delivery. Microneedle-mediated Transdermal and Intradermal Drug Delivery covers the major aspects relating to the use of microneedle arrays in enhancing drug delivery applications. It provides an overview of the various methods employed to design and produce microneedles, from the different materials involved to the importance of application methods. It carefully and critically reviews ongoing transdermal and intradermal delivery research using microneedles and includes the outcomes of in vivo animal and human studies. Importantly, it also discusses the safety and patient acceptability studies carried out to date. Finally, the book reviews the recent patents in microneedle research and describes the ongoing developments within industry that will determine the future of microneedle-mediated transdermal and intradermal drug delivery. By an expert author team with practical experience in the design and development of drug delivery systems this is the only text that provides a comprehensive review of microneedle research in transdermal and intradermal drug delivery.

Practical drug development approaches presented by leading experts Designed to support the development of new, effective therapeutics, Topical and Transdermal Drug Delivery: Principles and Practice explains the principles underlying the field and then demonstrates how these principles are put into practice in the design and development of new drug products. Drawing together and reviewing the latest research findings, the book focuses on practical, tested, and proven approaches that are backed by industry case studies and the authors' firsthand experience. Moreover, the book emphasizes the mechanistic information that is essential for successful drug product development. Topical and Transdermal Drug Delivery: Principles and Practice is divided into two parts: Part One, Current Science, Skin Permeation, and Enhancement Approaches, offers readers a fundamental understanding of the underlying science in the field. It describes the principles and techniques needed to successfully perform experimental approaches, covering such issues as skin permeation, enhancement, and assessment. Part Two, Topical and Transdermal Product Development, guides readers through the complete product development process from concept to approval, offering practical tips and cautions from experts in the field. This part also discusses regulations that are specific to the development of dermal drug products. The final chapter explores current and future trends, forecasting new development techniques and therapeutics. Throughout the book, the authors clearly set forth the basic science and experimental procedures, making it possible for researchers to design their own experimental approaches and accurately interpret their results. With contributions from experienced drug researchers, this text is highly recommended for all researchers involved in topical and transdermal product development who need to know both the state of the science and the standards of practice.

Presents authoritative state-of-the-art discussions of the key issues pertinent to transdermal drug delivery, examining those topics necessary to enable a critical evaluation of a drug candidate's potential to be delivered across the skin; from physical chemistry and assessment of drug permeability to available enhancement technolgies, to regulator
