概要

Activated charcoal binds methotrexate in the gut and can interrupt its enterohepatic recirculation, lowering its levels. This reduces the effect of therapeutic doses but is used deliberately in overdose.

この相互作用をわかりやすく説明すると

Activated 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.

Activated charcoal belongs to Gastrointestinal Tract; Methotrexate belongs to Oncology.

エビデンスレベル: Moderate

なぜ起こるのか

Adsorption of methotrexate in the gastrointestinal tract reduces absorption and enterohepatic reabsorption.

対処法

Separate charcoal from oral methotrexate doses unless it is being given for overdose. In overdose, consider repeated charcoal alongside leucovorin and supportive care.
