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.

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.

Percutaneous absorption is the development of transdermal drug delivery patches, as well as the treatment of skin disorders. The skin permeability of most drugs is low, but can be enhanced by several mechanisms including electric force.This volume provides coverage of assisted transdermal and topical delivery by the mechanisms of iontophoresis, electroosmosis and electroporation. It starts by introducing the terminology and outlines the historical background. A foundation of the theoretical concepts and mechanisms of iontophoresis and electroporation has been presented, followed by tips on the design of experimental systems for research in this area. Other topics discussed are human and clinical studies with iontophoresis; delivery of peptides, Proteins And Oligonucleotides; Combined Use Of Iontophoresis And electroporation for gene therapy; iontophoretic delivery of insulin for diabetes; and the current status of the commercial development on an iontophoretic patch. This book provides a wealth of theoretical and practical information not easily found in any other single source.

Transdermal Drug Delivery: Concepts and Application provides comprehensive background knowledge and documents the most recent advances made in the field of transdermal drug delivery. It provides comprehensive and updated information regarding most technologies and formulation strategies used for transdermal drug delivery. There has been recent growth in the number of research articles, reviews, and other types of publications in the field of transdermal drug delivery. Research in this area is active both in the academic and industry settings. Ironically, only about 40 transdermal products with distinct active pharmaceutical ingredients are in the market indicating that more needs to be done to chronicle recent advances made in this area and to elucidate the mechanisms involved. This book will be helpful to researchers in the pharmaceutical and biotechnological industries as well as academics and graduate students working in the field of transdermal drug delivery and professionals working in the field of regulatory affairs focusing on topical and transdermal drug delivery systems. Researchers in the cosmetic and cosmeceutical industries, as well as those in chemical and biological engineering, will also find this book useful. - Captures the most recent advancements and challenges in the field of transdermal drug delivery - Covers both passive and active transdermal drug delivery strategies - Explores a selection of state-of-the-art transdermal drug delivery systems

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.

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.

With the improvements in formulation science and certain transdermal delivery technologies, the non-invasive mode of drug delivery is now ready to compete with traditional methods of oral and injectible routes of drug delivery. The Handbook of Non-Invasive Drug Delivery Systems encompasses the broad field of non-invasive drug delivery systems that include drug delivery via topical, transdermal-passive, transdermal-active (device- aided enhanced penetration), trans-mucosal membrane, trans-ocular membrane as well as delivery via alveolar membrane from inhaled medication. Patient compliance has been found to be much higher when administrated by non-invasive routes and therefore they are considered to be a preferred mode of drug delivery. The book includes both science and technological aspects of new drug delivery systems. Its unique focus is that it is on new drug delivery systems that are considered to be "non-invasive". Other unique features include a chapter on Regulatory Aspects of non-invasive systems and one on FDA guidance for topical nano-drug delivery. Two chapters covering market trends and perspectives, as well as providing guidance to those marketing such systems are also included.
