Drug Name		Penicillamine				Zinc acetate
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 acetate due to formation of complexes caused by Penicillamine

Recommended Action
Management		Mineral supplements or other products containing polyvalent cations should be administered at least two hours before or two hours after the penicillamine dose if possible.
