More About This Title Metabolism of Drugs and Other Xenobiotics
English
A practice-oriented desktop reference for medical professionals, toxicologists and pharmaceutical researchers, this handbook provides
systematic coverage of the metabolic pathways of all major classes of xenobiotics in the human body. The first part comprehensively reviews
the main enzyme systems involved in biotransformation and how they are orchestrated in the body, while parts two to four cover the three
main classes of xenobiotics: drugs, natural products, environmental pollutants. The part on drugs includes more than 300 substances from
five major therapeutic groups (central nervous system, cardiovascular system, cancer, infection, and pain) as well as most drugs of abuse
including nicotine, alcohol and "designer" drugs. Selected, well-documented case studies from the most important xenobiotics classes illustrate general principles of metabolism, making this equally useful for teaching courses on pharmacology, drug metabolism or molecular
toxicology.
Of particular interest, and unique to this volume is the inclusion of a wide range of additional xenobiotic compounds, including food supplements, herbal preparations, and agrochemicals.

Pavel Anzenbacher heads the Department of Pharmacology at Palacky University, Olomouc (Czech Republic) and is vicepresident of the Czech Society of Clinical and Experimental Pharmacology and Toxicology. Having obtained his academic degrees from Charles University, Prague and from the Academy of Sciences of the Czech Republic he joined the Faculty of Medicine at Palacky University. His scientific contacts and stays have included e.g. the Princeton University, Vanderbilt University, Nashville, University of Connecticut, INSERM Montpellier, University of Lubeck, Technical University Berlin and Jagellonian University Cracow. Professor Anzenbacher has authored over 150 original scientific publications and has, among other honours, received the Fogarty Award of the USPHS.
Ulrich M. Zanger is deputy head of the Dr. Margarete Fischer-Bosch Institute of Clinical Pharmacology, Stuttgart (Germany). A chemist by training, he began to work on drug metabolism at the Biocenter of the University of Basel, Switzerland, where he obtained a PhD
degree in biochemistry. He undertook postdoctoral studies at the Southwestern Medical Center at Dallas, Texas, before returning to Basel and later moving to Stuttgart. His major research interests are in human drug metabolizing cytochromes P450 and in basic and clinical aspects
of pharmacogenetics/genomics. Professor Zanger has authored more than 130 scientific articles and is lecturing in pharmacology and toxicology at the University of Tübingen.

“Overall therefore, a book which can be read in its own right for the first half and then a valuable source of reference for the second half. A useful tome to have on the bookshelf for anyone in the field.” (British Toxicology Society, 1 July 2013)
