Complex formation Click to Show/Hide Mechanism Graph
Drug Name		Ferrous sulfate anhydrous				Baloxavir marboxil
Mechanism		Polyvalent cations				Binds to polyvalent cations
Key Mechanism Factor 1
		Factor Name		Chelation
		Factor Description		Chelation is a direct drug interaction that usually involves the formation of dimers or trimers, resulting in larger complexes and poorer absorption.
Mechanism Description		Decreased absorption of Ferrous sulfate anhydrous due to formation of complexes caused by Baloxavir marboxil
