NCIt definition : An intravenous colloidal solution containing trivalent iron (Fe3 ) chelated to isomaltosides,
used as iron replacement. The iron in iron isomaltoside 1000 is strongly bound to
the carbohydrate particles; each particle contains a trivalent iron core and a carbohydrate
shell of isomaltosides which protects and stabilizes the iron core. This results in
low levels of free iron and decreases inorganic, unbound iron-related toxicities thereby
allowing for administration of higher doses of iron as compared to other iron-containing
formulations. Upon parenteral administration and degradation of the carbohydrate shell,
the iron in iron isomaltoside 1000 is released and replenishes iron stores.;
