Drugs reference index «Floxuridine»


Pronunciation: (flox-YOUR-ih-deen)Class: Pyrimidine antimetabolite

Trade Names:FUDR- Powder for injection 500 mg- Solution for injection 100 mg/mL


The primary effect is to interfere with the synthesis of DNA and to a lesser extent inhibit the formation of RNA.



When given by rapid intra-arterial injection, floxuridine is rapidly catabolized to 5-fluorouracil. When given by continuous intra-arterial infusion, direct anabolism to floxuridine-monophosphate is enhanced. Floxuridine is metabolized in the liver.


The drug is excreted intact as urea, fluorouracil, alpha-fluoro-beta-ureidopropionic acid, dihydrofluorouracil, alpha-fluoro-beta-guanidopropionic acid, and alpha-fluoro-beta alanine in the urine. It also is expired as respiratory carbon dioxide.

Indications and Usage

Unlabeled Uses

Tumors of the liver, gallbladder, bile ducts, or kidneys.


Patients in a poor nutritional state, those with depressed bone marrow function or those with potentially serious infections.
