COMPARATIVE STUDY ON PHARMACOKINETICS OF 5-FU INJECTED VIA SPLENIC ARTERY AND AURICULAR VEIN IN RABBITS / 解放军医学杂志

ABSTRACT

To study the pharmacokinetics of 5 FU after splenic artery(IA) and auricular vein(IV) infusion, portal vein blood was collected for measurement to appraise the clinical value of treatment with this anti tumor drug via different routes on malignant hepatic neoplasms. 5 FU in portal vein blood was measured with high performance liquid chromatography. The results showed that the concentration of 5 FU in IA group was higher than that in the IV group. The peak concentration of 5 FU in the IA group was higher than that in the IV group by 64%. The area under the curve (AUC) of 5 FU in the IA group was larger than that in the IV group by 42%. It suggested that higher concentration of anti tumor drug in the portal vein could be obtained via splenic artery infusion, and it is valuable for the treatment of malignant hepatic neoplasms.
