摘　　要：目的:研究枸杞多糖对多柔比星在比格犬中的药代动力学性质的影响。方法:8只比格犬连续12d给予枸杞多糖胶囊(20mg/kg)或空胶囊,在第7天所有犬均静脉注射给予多柔比星(1.5mg/kg),本研究使用高效液相-荧光检测器对多柔比星的血药浓度进行检测。同时,本研究还对多柔比星对犬CYP3A活力的影响进行评价。结果:与单独给予多柔比星相比,联合给予枸杞多糖没有改变例如曲线下面积和清除率在内的多柔比星的药代动力学性质。但是,研究结果表明,枸杞多糖会抑制CYP3A的活性,CYP3A是多柔比星在犬中的重要代谢酶。结论:在给予多柔比星同时联合口服给予枸杞多糖不会影响多柔比星的药代动力学性质,但是会抑制CYP3A的活性。AIM：To investigate whether Lycium barbarum Polysaccharide（LBP）could modify the pharmacokinetic property of the doxorubicin（DOX）in Beagle dogs.METHODS：Eight Beagle dogs were treated with LBP capsule（20mg/kg）or vehicle for 12continuous days.Plasma concentration of DOX in two groups is monitored after i.v.bolus injection of DOX（1.5mg/kg）at day 7and was determined by reverse phase-high performance liquid chromatography with a fluorescence detector.Furthermore,the enzyme activity of cytochrome P450 3A（CYP3A）in two groups were evaluated.RESULTS：Compared with DOX group,LBP did not modify the pharmacokinetic profiles such as the area under curve and the clearance of DOX in the LPB＋DOX group.However,it is proved that LBP could inhibit the activity of CYP 3A,which is a critical metabolizing enzyme of DOX.There is a slight paradox between the inhibition of LBP to CYP 3Aand no influence of LBP to pharmacokinetic profiles of intravenous DOX.CONCLUSION：Co-administration of LBP inhibits CYP3A,the metabolizing enzyme of DOX,but does not affect the pharmacokinetic profiles of intravenous DOX.
