Abstract
Living systems have developed elimination mechanisms to dispose waste products and to protect themselves from exposure to potentially harmful chemical compounds. Protective strategies to limit such exposure include the existence of biological barriers with selective permeability, the chemical disposal of xenobiotics by chemical biotransformations, and the physical disposal of xenobiotics (or its biotransformation products) through excretion routes. This chapter discusses the enzymatic systems involved in drug metabolism and the strong integration of these systems with other elimination mechanisms.

Further Reading
Drug metabolism is a vast topic, and entire books have been written about it. Here, we intended to provide a summary of the more relevant points of drug biotransformation, but the chapter is far from exhaustive. For a much deeper insight on the topic, the reader is advised to Pearson and Wienkers’s Handbook of Drug Metabolism (currently in its 3rd edition by CRC Press); the Drug Metabolism Handbook edited by Nassar, Hollenberg, and Scatina (2008, Wiley & Sons); and the extensive and unbelievably comprehensive series of articles by Testa and Krämer, many of which have been included in the reference list of the present chapter.
