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.

There has been an increased interest among researchers in hydrogen-bonded interpolymer complexes since the first pioneering papers were published in the early 1960s. Several hundred research papers have been published on various aspects of complex formation reactions in solutions and interfaces, properties of interpolymer complexes and their potential applications. This book focuses on the latest developments in the area of interpolymer complexation via hydrogen bonding. It represents a collection of original and review articles written by recognized experts from Germany, Greece, Kazakhstan, Poland, Romania, Russia, UK, Ukraine, and the USA. It highlights many important applications of interpolymer complexes, including the stabilization of colloidal systems, pharmaceuticals, and nanomaterials.
Mucoadhesive polymers are widely used in the design of dosage forms for transmucosal drug delivery to the eye, respiratory, gastrointestinal and reproductive tracts. These routes of drug administration offer a number of advantages including improved drug bioavailability, reduced frequency of administration, and the avoidance for the use of injections. This book represents a collection of reviews and original research articles in the area of mucoadhesive polymers and dosage forms. It covers the design of mucoadhesive forms from commercially-available water-soluble polymers, their mixture and complexes as well as some materials, whose mucoadhesive properties were enhanced through chemical modification. With contributions from leading experts in mucoadhesive polymers and formulations, this book will be a very useful source of information for researchers in polymer, pharmaceutical and formulation sciences.
Development of strategies to assist the movement of poorly permeable molecules across biological barriers has long been the goal of drug delivery science. In the last three decades, there has been an exponential increase in advanced drug delivery systems that aim to address this issue. However, most proprietary delivery technologies that have progressed to clinical development are based on permeation enhancers (PEs) that have a history of safe use in man. This Special Issue entitled “Transmucosal Absorption Enhancers in the Drug Delivery Field” aims to present the current state-of-the-art in the application of PEs to improve drug absorption. Emphasis is placed on identification of novel permeation enhancers, mechanisms of barrier alteration, physicochemical properties of PEs that contribute to optimal enhancement action, new delivery models to assess PEs, studies assessing safety of PEs, approaches to assist translation of PEs into effective oral, nasal, ocular and vaginal dosage forms and combining PEs with other delivery strategies.

As one of the typical intermolecular interactions, hydrogen-bonding plays a significant role in molecular structure and function. When the hydrogen bond research system is connected with the photon, the hydrogen-bonding effect turns to an excited-state one influencing photochemistry, photobiology, and photophysics. Thus, the hydrogen bond in an excited state is a key topic for understanding the excited-state properties, especially for optoelectronic or luminescent materials.The approaches presented in this book include quantum chemical calculation, molecular dynamics simulation and ultrafast spectroscopy, which are strong tools to investigate the hydrogen bond. Unlike other existing titles, ...
