Iron Isomaltoside 1000

**Semantic type:** Pharmacologic Substance

**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.

**Synonyms:** - IRON ISOMALTOSIDE 1000 - Monofer
