This books theme and scope is the application of physical pharmacy, drug design, and drug regulations as they relate to produce effective dosage forms for drug delivery. The structure of the book begins with fundamentals related to physical pharmacy principles such as drug stability estimation, rheology, and interfacial properties; then, it moves on to explain how to incorporate these principles in product design. The last section of the book addresses the issues governing drug regulations as specified by the United States, European, and Japanese regulatory agencies. As such, the book features an overarching novel approach that integrates tripartite pharmaceutical development regulatory guidelines and requirements with the science and technology of pharmaceutical product design.
