      Drug Name Colesevelam Mycophenolic acid
      Mechanism Anion exchange resin/polymer Binds to anion exchange resin/polymer
      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 Colesevelam due to formation of complexes caused by Mycophenolic acid 

Recommended Action
      Management Given the risk of organ rejection associated with inadequate immunosuppressant blood levels, mycophenolic acid products should not be administered with cholestyramine or other agents that may interfere with enterohepatic recirculation or bind bile acids (e.g., activated charcoal).
