Mechanism of Penicillamine-Calcium glubionate anhydrous Interaction (Severity Level: Moderate)
Complex formation Click to Show/Hide Mechanism Graph
Drug Name		Penicillamine				Calcium glubionate anhydrous
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 Calcium glubionate anhydrous due to formation of complexes caused by Penicillamine

Recommended Action
Management		Mineral supplements or other products containing polyvalent cations (e.g., antacids or preparations containing antacids such as didanosine buffered tablets or pediatric oral solution) should be administered at least two hours before or two hours after the penicillamine dose. In addition, pharmacologic response to penicillamine should be monitored more closely whenever these products are added to or withdrawn from therapy, and the penicillamine dosage adjusted as necessary.
