      Drug Name Trimetrexate Glucarpidase
      Mechanism Glucarpidase substrate Glucarpidase recombinant enzyme
      Key Mechanism Factor 1
Factor Name Pharmacokinetics
Factor Description Alters the metabolism of the drug, leading to changes in the plasma concentration of the drug and affecting the pharmacological effects.
      Mechanism Description
  • Increased metabolism of Trimetrexate caused by Glucarpidase 

Recommended Action
      Management On theoretical grounds, caution is advised if glucarpidase is administered in combination with potential substrates such as folate antimetabolites other than methotrexate. With leucovorin, experts recommend administering it two to four hours before or after a dose of glucarpidase. The same precaution may be appropriate with other potential substrates of glucarpidase, although clinical data are currently lacking.
