Integrating aspects of physical pharmacy, biopharmaceuticals, drug delivery, and biotechnology, "Pharmaceutical Dosage Forms and Drug Delivery" elucidates basic physicochemical principles and their application in the design of dosage forms. The author addresses the relevance of these principles to the biopharmaceutical aspects of drugs. He explores the latest developments in the application of biomaterials, including polymers and biotechnology-based agents, to the development of novel dosage forms.The book covers physicochemical principles of dosage design, biopharmaceutical and physiological considerations, types of commonly used pharmaceutical dosage forms, introduction to polymeric biomaterials, protein and nucleic acid-based dosage forms, and novel and targeted drug delivery systems. It highlights the physicochemical parameters used for the design, development, and evaluation of biotechnological dosage forms and describes the biological barriers to drug absorption. Containing the right blend of mathematics, equations, diagrams, pictorials, and other pertinent information, this book provides a unified perspective that creates a greater overall understanding of basic science and cutting-edge technology.
