概要
Leucovorin stabilizes the binding of the active fluorouracil metabolite to thymidylate synthase, which enhances the cytotoxic effect of fluoropyrimidines. This can increase toxicities of capecitabine such as diarrhea, mucositis, hand-foot syndrome and myelosuppression.
この相互作用をわかりやすく説明すると
Capecitabine and Leucovorin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Capecitabine belongs to Oncology; Leucovorin belongs to Miscellaneous.
なぜ起こるのか
Leucovorin increases reduced folate pools, stabilizing the fluorodeoxyuridylate-thymidylate synthase complex and potentiating fluoropyrimidine activity.
対処法
Avoid combining unless it is part of a specifically designed regimen, as capecitabine labeling advises caution. If used, monitor closely for severe diarrhea and myelosuppression and reduce the capecitabine dose as needed.
