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.
