Ferric maltol is an orally active complex of a single ferric ion (Fe3+). Ferric maltol has tha potential for iron deficiency anemia treatment in inflammatory bowel disease[1].

The administration of Ferric maltol can increase transferrin saturation and levels of serum iron, serum ferritin, reticulocyte hemoglobin, and blood hemoglobin[1].

Animal studies show that iron that is not absorbed from Ferric maltol can remain in its chelated form at least throughout the small intestine, minimizing the risk of intestinal mucosal damage from free iron and potentially reducing local toxicity[1].
