吉西他滨低剂量延时输注的研究进展

Research Progress of Prolonged Low-dose Infusion for Gemcitabine

吉西他滨(gemcitabine,GEM)为抗嘧啶核苷酸代谢类药物。目前,GEM的标准给药方式为1 000~1 250 mg·m-2,30min静脉快速输注。但是,药理学研究表明,GEM延时输注可使细胞内有活性的GEM三磷酸盐达到最佳的蓄积速度,提示GEM延时输注在药动学方面要优于30 min快速输注。故本文对GEM低剂量延时输注的相关研究进行综述,以期为临床用药提供相关依据。

Gemcitabine（GEM） is a kind of anti-pyrimidine nucleotide metabolism drug. At present, the standard dose of GEM is 1 000-1 250 mg·m^-2, intravenous infusion for 30 min. However, pharmacological studies have shown that GEM with prolonged infusion can improve the accumulation rate of GEM triphosphate（d Fd CTP）, suggesting that prolonged infusion of GEM is superior to 30 min infusion in pharmacokinetics. This paper review the related research of GEM with prolonged low-dose infusion in order to provide the basis for it＇s clinical medication.
