Drug Detail:Floxuridine (Floxuridine [ flox-ure-i-deen ])
Drug Class: Antimetabolites
Usual Adult Dose for Liver Metastasis in Adenocarcinoma
Recommended dose: 0.1 to 0.6 mg/kg/day by continuous arterial infusion; the higher dosage ranges (0.4 mg to 0.6 mg) are usually used for hepatic artery infusion because the liver metabolizes the drug (thus reducing the potential for systemic toxicity)
Comments:
- Therapy can be given until adverse reactions appear. When these side effects have subsided, therapy may be resumed.
- The patient should be maintained on therapy as long as response to floxuridine continues.
Use: For the palliative management of gastrointestinal adenocarcinoma metastatic to the liver, when given by continuous regional intra-arterial infusion in carefully selected patients who are considered incurable by surgery or other means.

Other Comments
General:
- This drug should be used with extreme caution in poor risk patients with impaired renal or hepatic function or a history of high-dose pelvic irradiation or previous use of alkylating agents.
- All patients should be hospitalized for the first course of therapy because of the possibility of severe toxic reactions.
- This drug is not intended as an adjuvant to surgery.
- This drug is a highly toxic drug with a narrow margin of safety. Patients should be carefully supervised since therapeutic response is unlikely to occur without some evidence of toxicity.
