Toxicity and Toxicodynamics, Volume One in the Essentials of Pharmatoxicology in Drug Research series provides an overview on the essentials of toxicology, risk assessment and the mechanisms. Topics discussed include the types of cellular responses to chemical toxicants, mechanisms of drug toxicity, and their relevance to pharmaceutical product development. The book examines omics and computer-aided technologies for mechanistic and predictive toxicology and covers state-of-art testing in the evaluation of detrimental pathways, dose selection in toxicity studies, as well as the role of regulatory agencies in toxicity studies. In addition, there is also discussion on clinical interventions such as pharmacotherapy and managed care strategies for acute poisoning. This volume is a valuable resource to those learning more about the drug development process related to toxicology and those who want to get an update on newer concepts on the toxicology aspect of drug research.
