NCIt definition : The mesylate salt of an iron-chelating agent that binds free iron in a stable complex,
preventing it from engaging in chemical reactions. Deferoxamine chelates iron from
intra-lysosomal ferritin and ferrioxamine, a water-soluble complex excreted by the
kidneys and in the feces via the bile. This agent does not readily chelate iron bound
to transferrin, hemoglobin, myoglobin or cytochrome.;
