Physiological Pharmaceutics 2nd Edition has been written to meet the need for a high quality up to date and accessible pharmacology textbook. The book has a breadth of subject coverage designed to bridge the gap between classical pharmacy and the biological sciences giving students an overview of the biological environment in which drugs are expected to perform. Based upon the popular first edition, the second edition has been extensively revised and updated with the student in mind. It has undergone a thorough overhaul of its artwork and figures and includes the latest in new developments and research results. As in its predecessor, the authors have avoided any unnecessary mathematical complexity that is not central to the students understanding of the core subject. Physiological Pharmaceutics provides an integrated approach to the study of drug formulation in the body with the emphasis on the formulation variables rather than the drugs. The link between physiology and pharmaceutics is presented to give an essential background of biological principles for the pharmacy student.
