Over the past ten years several sophisticated in vitro test systems based on epithelial cell cultures have been introduced in the field of drug delivery. These models have been found to be very useful in characterizing the permeability of drugs across epithelial tissues, and in studying formulations or carrier systems for improved drug delivery and enhanced absorption. Compared to in vivo trials on animals or humans, cell culture models are faster, more convenient and cost effective, ethically advantageous and, most importantly, they can be more easily standardized and validated.This book provides a practical approach to contemporary cell culture-based in vitro techniques for drug transport studies at biological absorption barriers. It is an invaluable source of information for students attending graduate courses on this subject and pharmaceutical scientists working in industry or in academia.

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 Systemsdiscusses 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 technologist

The incorporation of nanomaterials into products can improve performance, efficiency, and durability in various fields ranging from construction, energy management, catalysis, microelectronics, plastics, coatings, and paints to consumer articles such as foods and cosmetics. But innovation never comes at zero risk. The potential hazards resulting from human exposure during production, use, or disposal has raised concerns and targeted research early on. Safety of Nanomaterials along Their Lifecycle: Release, Exposure, and Human Hazards presents the state of the art in nanosafety research from a lifecycle perspective. Although major knowledge gaps still exist, solid data are now available to identify scenarios of critical risk as well as those of safe nanomaterial use for our benefit. The book is divided into four parts: characterization, hazard, release and exposure, and real-life case studies. To improve coherence throughout the book, various chapters review the same suite of well-characterized, judiciously chosen, and identical industrial nanomaterials. The book is a helpful resource to professionals in product development, industrial design, regulatory agencies, and materials scientists and engineers involved in the safety of nanomaterials.
