TY - CHAP M1 - Book, Section TI - Chapter 11. Drug Elimination and Hepatic Clearance A1 - Shargel, Leon A1 - Wu-Pong, Susanna A1 - Yu, Andrew B.C. Y1 - 2012 N1 - T2 - Applied Biopharmaceutics & Pharmacokinetics, 6e AB - The decline from peak plasma concentrations after drug administration results from drug elimination or removal by the body. The elimination of most drugs from the body involves the processes of both metabolism (biotransformation) and renal excretion (see Chapter 6). For many drugs, the principal site of metabolism is the liver. However, other tissues or organs, especially those tissues associated with portals of drug entry into the body, may also be involved in drug metabolism. These sites include the lung, skin, gastrointestinal mucosal cells, microbiological flora in the distal portion of the ileum, and large intestine. The kidney may also be involved in certain drug metabolism reactions.
