Summary

This is a straightforward, uncomplicated, basic, introductory book that presents only the material essential to provide a good foundation in pharmacokinetics and pharmacodynamics designed by the author to teach quantitative pharmacokinetics and pharmacodynamics (PK and PD) in a novel way. It consists of the book and integrated interactive computer modules. Modules and exercises based on them are are available online via a companion website, and they are integrated into relevant parts of the book to reinforce the concepts presented there. The modules allow students to carry out and experiment with simulations and observe in a dynamic manner, how specific PK / PD characteristics impact the dose-response relationship for drugs. By combining a pharmacokinetic model with a pharmacodynamic model of drug response, the author provides a complete model of the relationship that allows the drug resopnse to be estimated at any time after dose. The book provides an understanding of the new developments in pharmacodynamics and ties together several disciplines of pharmaceutical sciences.

Author Biography

Sara E. Rosenbaum, PhD, is Professor of Biomedical and Pharmaceutical Sciences at the University of Rhode Island, where she teaches courses in pharmacokinetics. She is also the former editor-in-chief of Clinical Research and Regulatory Affairs. Dr. Rosenbaum's research interests concentrate on the development and application of pharmacokinetic and pharmacodynamic models that build our understanding of the drug dose-response relationship.
