Floxuridine (FUDR)
Other Medications · Approved since 1970
Description
Floxuridine (FUDR) is a fluoropyrimidine antimetabolite chemotherapy agent used primarily for regional therapy in colorectal cancer patients with liver metastases. It is most commonly administered via hepatic arterial infusion (HAI) to deliver high concentrations of chemotherapy directly to liver tumors while minimizing systemic toxicity. The drug is also utilized in hyperthermic intraperitoneal chemotherapy (HIPEC) protocols for patients with peritoneal metastases from colorectal cancer.
Mechanism of Action
Floxuridine is converted intracellularly to 5-fluorouracil and then to active metabolites that inhibit thymidylate synthase, a key enzyme required for DNA synthesis. This inhibition depletes thymidine triphosphate pools and incorporates fraudulent nucleotides into DNA, ultimately leading to cell cycle arrest and apoptosis in rapidly dividing cancer cells.
