The therapeutic benefits of administering drugs through the skin have been recognized for many years and have been capitalized upon in commercially successful and important transdermal delivery systems, such as estradiol patches for hormone replacement and nicotine patches as aids to smoking cessation. Transdermal and Topical Drug Delivery addresses all aspects of how to deliver drugs to the skin for local effects or across the skin for systemic therapy. Starting with a discussion of the principles underlying the area, the text expands into strategies used to deliver drugs effectively. This should be a valuable practical guide for the clinical delivery of drugs.

Advances in the pharmaceutical and cosmetic sciences have propelled the development of transdermal and topical therapeutic systems into a technologically revolutionary phase. This book offers an authoritative guide to the development of delivery systems. Discussions by research and industry experts include methods for clinical assessment, percutaneous permeation enhancers, and formulation approaches to topical drug delivery. It also addresses IND, ANDA, NDA, and PLA filings for transdermal products with the FDA. The book contains practical information, step-by-step guidance, numerous references, and a complete index to help readers quickly locate the information they need. Features

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.

Topical and transdermal drug delivery systems (TDDs) have several advantages over traditional drug delivery methods, as they can be less invasive, more sanitary, more cost-effective, and may result in better patient compliance. TDDs play a significant role in therapeutics with a variety of preparations and approaches designed by expert formulation scientists. This volume integrates a wide variety of case studies, research, and theories to reveal their diversity and capture the novel approaches of transdermal and topical drug delivery employed by developers and content experts in the field. It provides an abundance of important information and state-of-the-art research on topical and transdermal drug delivery systems and addresses the basics of drug delivery systems, strategies to enhance permeation across membranes, and formulation and evaluation of diverse dosage forms. The volume presents an evaluation of the pros and cons of conventional drug delivery systems against TDDs and discusses the nuances of micro- and nano-systems in TDDs. The extraordinary packages of nano systems (vesicular systems, polymeric nanoparticles, nanoemulsion and dendrimers) are broadly discussed, and their applications are reviewed through a transdermal route. The book looks at TDDs and the main nanoparticles used in skin diseases and lesions of the aging, such as psoriasis, vitiligo, cancer, lesions of the aging and others. Chapters also discuss polymeric micelles in topical and transdermal delivery; microneedles; emulsion, nanoemulsion and microemulsion; TDDs in pulmonary drug delivery systems; nanoencapsulated nasal drug delivery systems; skin sensitivity and irritation testing for transposing transdermal drug delivery systems; and regulatory aspects of drug development for dermal products. Topical and Transdermal Drug Delivery Systems: Applications and Prospects will be a valuable resource for pharmaceutical scientists and researchers, industry professionals, and academicians and students of the pharmaceutical and biomedical sciences.

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.

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

Particularly in healthcare fields, there is growing movement away from traditional lecture style course towards active learning and team-based activities to improve learning and build higher level thinking through application of complex problems with a strong foundation of facts and data. Essential Pharmaceutics is suited to this modern teaching style, and is the first book of its kind to provide the resources and skills needed for successful implementation of an active learning pharmaceutics course.This text offers a format that is specifically suited for integration in an active learning, team-based classroom setting. It is ideal for self-learning for the beginning pharmaceutics student, based upon the extensive utilization of figures, tables, and its overview of essential topics in pharmaceutics. Also unique to this text is the integration of case studies based upon modern pharmaceutical products which are designed to reinforce importance pharmaceutical concepts and teach essential skills in literature review and patent searching. Case studies covering all topics covered in the text have been developed by the authors that allow application of the content in the flipped-classroom pharmaceutical course.
