Methotrexate Monitoring Tool

Methotrexate Monitoring Tool

Visit MTXPK.org to see if your patient is clearing MTX as expected. This tool was independently developed by Dr. Laura Ramsey of Cincinnati Children’s Medical Center and lead author of the Consensus Guidelines5 and provides:
 

  • A free, open-access clinical decision-making tool for monitoring plasma MTX elimination in both adult and pediatric patients
  • No log in required
  • No patient data stored on the website (but can be stored to local computer and browser)
  • Visual display of data shows expected and actual MTX elimination curves along with serum creatinine trend and predicted time to reach discharge threshold levels
  • Patient report can be downloaded and saved as PDFs or printed
