Complex formation Click to Show/Hide Mechanism Graph
Drug Name		Elvitegravir				Zinc chloride
Mechanism		Binds to polyvalent cations				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 Zinc chloride due to formation of complexes caused by Elvitegravir

Recommended Action
Management		If concomitant use is required, monitor for virologic efficacy and administer the INSTI such as elvitegravir or raltegravir at least 2 hours before or 6 hours after supplements containing polyvalent cations such as zinc.
