      Drug Name Digitoxin Magnesium hydroxide
      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 Magnesium hydroxide due to formation of complexes caused by Digitoxin
