Topical Applications and the Mucosa


Book Description

An excellent summary and review Mucosal membranes have unique anatomical and physiological properties -- differing from those of the keratinized epithelium -- which affect drug or chemical absorption. This makes the diagnosis and treatment of diseases of the mucosa a challenge to dermatologists as well as gynecologists, since many conditions are difficult to recognize and well-established principles of skin disease treatment do not apply to the mucosa. This volume is exclusively devoted to the mucosal membrane and delivers a better understanding of this distinctive area. Subsequently to introductory chapters on the morphology and physiology of the mucosa, the topical treatment of impaired mucosal membranes is discussed. A third section covers the wide spectrum of consumer products applied on mucosal surfaces. Finally, the safety of products for mucosal membranes is reviewed. Providing an excellent summary and review of the latest findings and topical applications, this book will be of great value to physicians and clinicians in dermatology or gynecology, pharmacists, scientists and toxicologists who are involved in the development of products for mucosal membranes.

Bioadhesives in Drug Delivery


Book Description

This important and unique book comprises 12 chapters divided into three parts examining the fundamental aspects, bioadhesive formulations, and drug delivery applications. Understanding the phenomenon of bioadhesion i.e. its theories or mechanism(s) are of critical importance in developing optimum bioadhesive polymers (used in bioadhesives). Such bioadhesive polymers are the key for exhibiting the process of bioadhesion, controlled/sustained release of drugs, and drug targeting. The use of bioadhesives restricts the delivery system to the site of interest and thus offers a useful and efficient technique for targeting a drug to the desired location for a prolonged duration. This book addresses the various relevant aspects of bioadhesives in drug delivery in an easily accessible and unified manner. The book containing 12 chapters written by eminent researchers from many parts of the globe is divided into three parts: Part 1: Fundamental Aspects; Part 2: Bioadhesive Formulations; Part 3: Drug Delivery Applications. The topics covered include: Theories and mechanisms of bioadhesion; bioadhesive polymers for drug delivery applications; methods for characterization of bioadhesiveness of drug delivery systems; bioadhesive films and drug delivery applications; bioadhesive nanoparticles; bioadhesive hydrogels and applications; ocular biodhesive drug delivery systems; buccal bioadhesive drug delivery systems; gastrointestinal bioadhesive drug delivery systems; nasal bioadhesive drug delivery systems; vaginal drug delivery systems; pulmonary bioadhesive drug delivery systems.




Mucoadhesive Materials and Drug Delivery Systems


Book Description

Mucoadhesion defined as attachment of synthetic or natural materials to mucosal tissues has been widely exploited in pharmaceutical forms. This multi-author book provides an up-to-date account of current research on mucoadhesive materials and drug delivery systems. The introductory section describes the structure and physiology of various mucosal surfaces (oral, nasal, ocular, gastrointestinal and vaginal mucosa). This is followed by chapters on the various methods used to study mucoadhesion and to characterise mucoadhesive properties of various dosage forms. The final section will summarise information on traditional and novel types of mucoadhesive materials, such as chitosan, thiomers, and liposome-based formulations. This book is unique as there is currently no modern book considering mucoadhesion - all other existing books on the topic are either narrowly focused or more than 10 years old. Furthermore, each contributor offers specialist perspectives from a variety of global locations in both industrial and academic research centres.

pH of the Skin: Issues and Challenges


Book Description

The concept of expressing acidity as the negative logarithm of the hydrogen ion concentration was defined and termed pH in the beginning of the 20th century. The general usefulness of the pH concept for life science was recognized and later gained importance to analytical research. Reports on results of pH measurements from living skin established the term acid mantle - the skin's own protective shield that maintains a naturally acid pH. It is invisible to the eye but crucial to the overall wellbeing of skin. Chronic alkalization can throw this acid mantle out of balance, leading to inflammation, dermatitis, and atopic skin diseases. It is therefore no surprise, that skin pH shifts have been observed in various skin pathologies. It is also obvious that the pH in topically applied preparations may play an important role. Optimal pH and buffer capacity within topical preparations not only support stability of active ingredients and auxiliary materials, but may also increase absorption of the non-ionized species of an acidic or a basic active ingredient. They may even open up opportunities to modify and "correct" skin pH and hence accelerate barrier recovery and maintain or enhance barrier integrity. Further efforts are needed to standardize and improve pH measurements in biological media or pharmaceutical/cosmetic vehicles to increase and ensure quality, comparability, and relevance of research data. In this volume, we present a unique collection of papers that address past, present and future issues of the pH of healthy and diseased skin. It is hoped that this collection will foster future efforts in clinical and experimental skin research.
