Absorption, Distribution, and Elimination of Toxicants

This topic delves into the toxicokinetic principles governing the fate of xenobiotics in the body, a critical module for tertiary students in pharmacology, toxicology, and biomedical sciences in Zambia. It covers mechanisms of absorption across membranes (GI, pulmonary, dermal), distribution volumes and storage depots (plasma proteins, fat, bone), and routes of elimination (renal, biliary, pulmonary). For Zambian university and college learners, understanding ADME processes is essential for predicting the onset, intensity, and duration of toxic effects, designing detoxification strategies, and interpreting pharmacokinetic data. This knowledge is vital for exam success and for future roles as clinical toxicologists, pharmacologists, or regulatory scientists in Zambia, where optimizing drug therapy and managing poisonings are key healthcare objectives.
