摘要: 目的: 研究溴泰君(W198)在Beagle犬体内毒代动力学,为临床试验提供依据。方法: 采用HPLC紫外或荧光检测方法测定Beagle犬静脉注射溴泰君、阿霉素以及溴泰君与阿霉素联合给药后生物样品中溴泰君和阿霉素的浓度。结果: Beagle犬静脉注射溴泰君15 mg·kg-1·d-1,第1次、第3次、第72次给药后的血清药物浓度-时间曲线下的面积(AUC0-24h分别为 6.15±0.66、26.55±9.43 和33.63±2_31 mg·h-1·L-1。Beagle犬静脉注射溴泰君15 mg·kg-1,第1次和第3次给药后的血清药物 AUC0-24h分别为 0.70±0.21 和 1.19±0.19 mg·h-1·L-1。溴泰君与阿霉素联合给药时,溴泰君连续给药3次、阿霉素给药1次和溴泰君连续给药39次、阿霉素给药3次后溴泰君的血清药物AUC0-24h分别为 25.52±6.04 和 42.60±4.14 mg·h-1·L-1;阿霉素的血清药物AUC0-24h分别为 0.39±0.05 和 0.77±0.19mg·h-1·L-1结论: 溴泰君和阿霉素连续多次给药后药物在动物体内均有明显蓄积作用。联合给药后溴泰君对阿霉素的消除似有促进作用,揭示溴泰君可以使阿霉素的系统暴露量减低,有利于降低阿霉素的毒性。

Abstract: AIM: To study the toxicokinetics after single or combination administration of bromotetrandrine (W198) and adriamycin in beagle dogs. METHODS: The concentrations of W198 and adriamycin in biological samples were determined by HPLC with ultraviolet and fluorescence detection. RESULTS: After successive in-travenous administration of 15 mg·kg-1 W198, the values of AUC0-24h of W198 were 6.15±0.66, 26.55±9.43 and 33.63±2.31 mg·h-1·L-1 for 1st, 3rd and 72nd administration, respectively, After successive in-travenous administration of 15 mg·kg-1 adriamycin, the values of AUC0-24h of adriamycin were 0.70±0.21 and 1. 19±0.19 mg·h-1·L-1 for 1st and 3rd administration, respec-tively.After successive intravenous combination administration of W198 and adriamycin, the values of AUC0-24h of W198 were 25.52±6.04 and 42.60±4.14 mg·h-1·L-1, and the AUC0-24h of adriamycin were 0.39±0.05 and 0.77±0.19 mg·h-1·L-1 for 3rd administration of W198 combined with 1st administration of adriamycin and 39th administration of W198 combined with 3rd administration of adriamycin, respectively. CONCLUSION: Both bro-motetrandrine and adriamycin have significantly accumula-tion effects in beagle dogs after successive intravenous ad-ministration, and bromotetradrine can reduce the systemic exposure of adriamycin after co-administration of the two drugs.
