title: High-performance liquid chromatographic method for the simultaneous measurement of floxuridine and fluorouracil in human body fluids.
abstract: A method for the simultaneous measurement of floxuridine (5-fluorodeoxyuridine) and fluorouracil in human plasma and peritoneal fluid has been developed. This method utilizes high-performance liquid chromatographic analysis with a Zorbax RX column (25 cm x 4.6 mm I.D.) plus a guard cartridge of the same material. The sensitivity limits for this assay are 0.25 mumol/l in a 20-microliters sample. The detection limit at a signal-to-noise ratio of 3 is 2.5 nmol/l. This procedure has been used to quantitatively measure concentration versus time profiles of floxuridine and fluorouracil in plasma and peritoneal fluid of human patients after receiving intraperitoneal administration of floxuridine.
