4 Pharmacology and Biochemistry
4.1 Metabolism/Metabolites

Antimony is widely distributed throughout the body. The hair and skin contain the highest levels of antimony. The adrenal glands, lung, large intestine, trachea, cerebellum, and kidneys also contain relatively high levels of antimony. Blood is the main vehicle for the transport of absorbed antimony to various tissue compartments of the body. Antimony is a metal and, therefore, does not undergo catabolism. Antimony can covalently interact with sulfhydryl groups and phosphate, as well as numerous reversible binding interactions with endogenous ligands (e.g., proteins). It is not known if these interactions are toxicologically significant. Antimony is excreted via the urine and feces. Some of the fecal antimony may represent unabsorbed antimony that is cleared from the lung via mucociliary action into the esophagus to the gastrointestinal tract. (L741)
