Thoroughly updated, this second edition is the most comprehensive reference on the methods available for the enhancement of percutaneous penetration. The book examines a broad scope of chemical enhancers and various physical methods of enhancement. The range of chemicals discussed is, arguably, unsurpassed anywhere in the literature. This edition contains comprehensive descriptions of the latest techniques and several chapters cover the modern analytical techniques adapted to assess and measure penetration enhancement. New to this volume are chapters addressing penetration retardation, important for substances such as sunscreen agents, for which skin penetration is not desirable.

This reference work - written by more than 35 leading international experts in the field of percutaneous penetration - fully explains the mechanisms and means of enhanced skin absorption in drug therapy.;The book identifies the features that an enhancer should possess for maximum activity and addresses underlying physico-chemical factors of the penetrant that affect the drug absorption process.;Pharmaceutical Skin Penetration Enhancement introduces all techniques used for basic research into skin penetration enhancement; reviews the advantages and limitations of various chemical enhancers; compares the use of physical enhancement during the processes in iontophoresis; and more.;Containing over 180 drawings, photographs, micrographs, and tables, and providing nearly 1000 bibliographic references, Pharmaceutical Skin Penetration Enhancement is a practical resource for both investigators conducting fundamental research in the field and for those working in an industrial setting, including pharmaceutical scientists, dermatologists, toxicologists, and cosmetic chemists, and upper-level undergraduate and graduate students in these disciplines.
Providing a significant cross-fertilization of ideas across several disciplines, Enhancement in Drug Delivery offers a unique comprehensive review of both theoretical and practical aspects of enhancement agents and techniques used for problematic administration routes. It presents an integrated evaluation of absorption enhancers and modes for promoting absorption that is especially valuable to those involved with the development of pharmaceutical, cosmetic, bioengineered, and medical products, as well as graduate students looking to study this intriguing field and those professionals involved with patents and regulatory issues. Organized by routes of administration, the book is divided into eight major sections: oral, rectal, buccal/sublingual, dermal/transdermal, nasal, vaginal/uterine, ocular, and brain. It offers fundamental as well specialized information including current findings on— · Surfactant use to accelerate macromolecule input · Targeted gastrointestinal delivery and enhanced absorption of lipophilic drugs · Permeation issues in rectal absorption · Chemical means of enhancement · Carriers for enhanced delivery to and across the skin · Methods associated with breaching the skin · Promoted buccal and sublingual absorption · Emerging ocular, nasal, vaginal, and uterine delivery systems · Carriers for overcoming the blood brain barrier Those investigators primarily involved with one specific route of delivery will be able to learn of helpful concepts and find additional stimulation from reading the approaches others have used within and outside their own spheres of activity. Readers are likely to find the same enhancer tested for various administration routes and in diverse experimental models. By understanding the properties and behavior of the enhancers operating within such systems, they may well find the inspiration needed to develop appropriate enhancing delivery methods for new applications.

This authoritative volume explores advances in the techniques used to measure percutaneous penetration of drugs and chemicals to assess bioavailability and bioequivalence and discusses how they have been used in clinical and scientific investigations. Seven comprehensive sections examine topics including in vitro drug release, topical drugs products, clinical studies, and guidelines and workshop reports, among others. The book also describes how targeted transdermal drug delivery and more sophisticated mathematical modelling can aid in understanding the bioavailability of transdermal drugs. The first edition of this book was an important reference guide for researchers working to define the effectiveness and safety of drugs and chemicals that penetrated the skin. This second edition contains cutting-edge advances in the field and is a key resource to those seeking to define the bioavailability and bioequivalence of percutaneously active compounds to improve scientific and clinical investigation and regulation.

Dendrimers are repeatedly branched and roughly spherical large molecules. They can be used in various medical applications, such as anticancer polymeric nanomedicines and nanocarriers, gene carriers and vectors in gene delivery, contrast agents for molecular imaging and vaccines against infectious diseases and cancer. The highly branched, multivalent nature and molecular architecture of dendrimers make them ideal tools for a variety of tissue engineering applications. This book describes different categories of dendrimers, their biomedical and physico-chemical applications as well as convergent and divergent syntheses, click chemistry and ligation strategies. It is a rich source of information for researchers in biochemistry and pharmacology working on drug development as well as for organic chemists who are engaged in synthesis of dendrimers.

Development of moisturizers is a scientific and artistic discipline, where consumer insights are also needed. This new book bridges the gap between the moisturizers and the skin by covering all the essential information required to tailor the use of moisturizers to particular disorders and patients. Important aspects of skin biochemistry and barrier function are explained, and the ingredients and treatment effects of moisturizers are explored in depth. Careful attention is paid to controversies, including the role of certain moisturizers in inducing dryness/eczema, asthma, and comedones. The information provided in this unique book will enable the reader to go beyond the traditional thinking regarding skin care. The novel insights offered will suggest the properties required for a new generation of moisturizing treatments that more effectively improve the quality of life.
