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; and 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.

This invaluable reference presents a comprehensive review of the basic methods for characterizing bioadhesive materials and improving vehicle targeting and uptake-offering possibilities for reformulating existing compounds to create new pharmaceuticals at lower development costs. Evaluates the unique carrier characteristics of bioadhesive polymers and their power to enhance localization of delivered agents, local bioavailability, and drug absorption and transport! Written by over 50 international experts and reflecting broad knowledge of both traditional bioadhesive strategies and novel clinical applications, Bioadhesive Drug Delivery Systems discusses mechanical and chemical bonding, polymer-mucus interactions, the effect of surface energy in bioadhesion, polymer hydration, and mucus rheology analyzes biochemical properties of mucus and glycoproteins, cell adhesion molecules, and cellular interaction with two- and three-dimensional surfaces covers microbalances and magnetic force transducers, atomic force microscopy, direct measurements of molecular level adhesions, and methods to measure cell-cell interactions examines bioadhesive carriers, diffusion or penetration enhancers, and lectin-targeted vehicles describes vaginal, nasal, buccal, ocular, and transdermal drug delivery reviews bioadhesive interactions with the mucosal tissues of the eye and mouth, and those in the respiratory, urinary, and gastrointestinal tracts explores issues of product development, clinical testing, and production and more! Amply referenced with over 1400 bibliographic citations, and illustrated with more than 300 drawings, photographs, tables, and display equations, Bioadhesive Drug Delivery Systems serves as a sound basis for innovation in bioadhesive systems and an excellent introduction to the subject. This unique reference is ideal for pharmaceutical scientists and technologists; chemical, polymer, and plastics engineers; biochemists; physical, surface, and colloid chemists; biologists; and upper-level undergraduate and graduate students in these disciplines.

Bioadhesion is often defined as the state in which two materials, at least one of which is biological in nature, are held together for extended periods of time by interfacial forces. It is an area of active multidisciplinary research, where engineers, scientists-including chemists, physicists, biologists, and medical experts-materials' producers, a

This comprehensively written text covers, in-depth, all aspects of bioadhesive systems. Bioadhesive systems are presently playing a major role in the field because of their ability to maintain a dosage form at a precise body-site for a prolonged period of time over which the active principle is progressively released. Included in this book are descriptions of the different mucosae in healthy and pathological situations, a theoretical approach of polymers-mucin interactions, and a comparative description of the methods used to evaluate bioadhesion. Up-to-date reviews of pharmaceutical applications are also given - subdivided according to the route of administration and type of system. It also contains a chapter devoted to the fundamentals of bioadhesion. This reference is an indispensable guide for researchers in the pharmaceutical field as well as academic researchers.

Green Adhesives: Preparation, Properties and Applications deals with the fabrication methods, characterization, and applications of green adhesives. It also includes the collective properties of waterborne, bio, and wound-healing green adhesives. Exclusive attention is devoted to discussing the applications of green adhesives in biomedical coatings, food, and industrial applications.

The book provides a single volume covering detailed descriptions about various delivery systems, their principles and how these are put in use for the treatment of multiple diseases. It is divided into four sections where the first section deals with the introduction and importance of novel drug delivery system. The second section deals with the most advanced drug delivery systems like microbubbles, dendrimers, lipid-based nanoparticles, nanofibers, microemulsions etc., describing the major principles and techniques of the preparations of the drug delivery systems. The third section elaborates on the treatments of diverse diseases like cancer, topical diseases, tuberculosis etc. The fourth and final section provides a brief informative description about the regulatory aspects of novel drug delivery system that is followed in various countries.

ADHESIVES IN BIOMEDICAL APPLICATIONS Uniquely provides up-to-date and comprehensive information on adhesives in biomedical applications in an easily accessible form. Adhesives are gaining popularity in many and varied biomedical applications as they are being used as a replacement for sutures and staples, which have the disadvantages such as scarring, infection, keloid formation, poor skin healing, or hernia in the case of abdominal sutures. On the other hand, adhesives dramatically reduce healthcare costs, significantly reduce time spent in surgery, curb the risks of bleeding, and are generally easy to use. Adhesives also find their use in diagnostic imaging, various biomedical devices, dental adhesives, dermal adhesives, etc. Adhesives in Biomedical Applications contains eleven chapters and is divided into two parts: Part 1: General Topics; and Part 2: Specific Adhesives, Characteristics, and Applications. Topics covered include: historical developments of various adhesives for biomedical applications; global industry development and analysis of adhesives for biomedical applications; biomedical adhesives; bioadhesion: fundamentals and mechanisms; fibrin glue; herbal bioactives-based mucoadhesive drug delivery systems; adhesive hydrogels; adhesives in dermal patches; medical adhesives from extracted mussel adhesive proteins; dental adhesives; and the role of adhesive-based systems for diagnostic imaging and theranostic applications. Audience The book will be used by adhesionists, adhesive technologists, polymer scientists, materials scientists, as well as those involved with biomedical devices and bioimplants such as medical doctors, surgeons, cosmetologists, as well as engineers in the pharmaceutical industry.
