Magnesium can bind oral ibandronate and reduce its already very low bioavailability.
Every entry follows the same shape: what is happening, the mechanism, and the recommendation.
What is happening. Magnesium can bind oral ibandronate and reduce its already very low bioavailability.
Mechanism. Divalent cation chelation in the gastrointestinal tract.
Recommendation. Avoid magnesium before and for at least 60 minutes after ibandronate; later-day dosing is preferred.
Space the doses apart by at least this window to avoid the conflict.
