摘要
Glucarpidase rapidly breaks methotrexate down into DAMPA, which cross-reacts in immunoassays and falsely elevates measured methotrexate. This can lead to misjudged rescue dosing for roughly two days.
用白話說明這項交互作用的意義
Glucarpidase and Methotrexate can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Glucarpidase belongs to Miscellaneous; Methotrexate belongs to Oncology.
為什麼會發生
Enzymatic cleavage of methotrexate to DAMPA and glutamate lowers true levels while DAMPA interferes with immunoassays.
處置方式
Measure methotrexate with a chromatographic method (e.g., HPLC) for at least 48 hours after glucarpidase. If only immunoassay is available, interpret results with caution.

Can I take Glucarpidase with Methotrexate?
MediHelp rates the interaction as moderate. Glucarpidase and Methotrexate can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken. Glucarpidase rapidly breaks methotrexate down into DAMPA, which cross-reacts in immunoassays and falsely elevates measured methotrexate. This can lead to misjudged rescue dosing for roughly two days.
How serious is the interaction between Glucarpidase and Methotrexate?
MediHelp rates it moderate, on a four-level scale (minor, moderate, major, contraindicated) based on published labels and references. What to do, in brief: Measure methotrexate with a chromatographic method (e.g., HPLC) for at least 48 hours after glucarpidase. If only immunoassay is available, interpret results with caution.
What other medicines interact with Glucarpidase?
MediHelp also lists interactions of Glucarpidase with, for example, Leucovorin, Folic acid, Pemetrexed. The full list is on the Glucarpidase page.
