摘要
Leucovorin is deliberately combined with fluorouracil to enhance its cytotoxic effect, but it also increases fluorouracil toxicity, particularly diarrhea, mucositis and myelosuppression. Severe gastrointestinal toxicity can be dangerous, especially in older patients.
用白話說明這項交互作用的意義
Fluorouracil 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.
Fluorouracil belongs to Oncology; Leucovorin belongs to Miscellaneous.
為什麼會發生
Leucovorin supplies reduced folate that stabilizes the binding of fluorodeoxyuridylate to thymidylate synthase, enhancing both efficacy and toxicity.
處置方式
Use established regimen doses of fluorouracil when combined with leucovorin and monitor blood counts and for diarrhea and mucositis. Interrupt therapy and reduce the dose for significant toxicity.
