概要
Activated charcoal adsorbs methotrexate in the gut and interrupts its enterohepatic circulation, decreasing exposure. This can reduce therapeutic effect with routine use but can help limit toxicity in overdose.
この相互作用をわかりやすく説明すると
Charcoal 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.
Charcoal belongs to Gastrointestinal Tract; Methotrexate belongs to Oncology.
なぜ起こるのか
Charcoal binds methotrexate in the gastrointestinal lumen, reducing absorption and biliary reabsorption.
対処法
Do not give charcoal with oral methotrexate therapy; separate doses by several hours if charcoal is needed. In toxicity, charcoal may be used alongside leucovorin and monitoring of methotrexate levels and renal function.
