摘要
研究通过建立酶联免疫吸附分析法测定患者血浆中安替安吉肽浓度,并对静脉滴注7.5,15mg/m。安替安吉肽后的药代动力学进行了研究。利用棋盘法确定实验用的抗原包被浓度为1:3200,安替安吉肽单克隆抗体包被浓度为1:64000,该方法在线性范围5~640ng/mL内相关性良好,回归方程为y=0.36931x-0.19499(R2=0.9962),批内及批间精密度RSD值均小于8%,回收率为100.57%-102.37%。药代动力学分析结果显示:单次静脉滴注7.5,15mg/m。安替安吉肽后AUC0-135和AUC0-150分别为(2067.829±384.392),(9858.611±804.555)ng/(L·min),AUC0-∞分别为(2110.049±382.736),(9953.023±785.602)ng/(L·min),Cmax分别为(22.581±6.957),(153.150±21.963)ng/mL,T1/2分别为(9.179±2.756),(7.553±0.366)min;实验表明,本测定方法灵敏准确,特异性强,适用于静脉滴注安替安吉肽后肿瘤患者血浆中安替安吉肽浓度的测定及其药代动力学的研究。
Through establishing enzyme-linked immunosorbent assay,was detected each plasma concentration of antiangiotide in tumor patients and was conducted the pharmacokinetic research after intravenous drip of 7.5 mg/m2 ,15 mg/m2 antiangiotide. According to the results of the checkerboard method, we obtained the antigen concentration of 1 : 3 200 dilution and the monoclonal antibody concentration of 1:64 000 dilution. The linear range of the method was 5 - 640 ng/mL. Regression equation was y = 0. 369 31 x - 0. 194 99 (R2 = 0. 996 2). The method was evaluated to have good recovery ratio ( 100.57 % - 102.37 % ) . The RSD for intra- assay and those for inter-assay were all within 8%. According to pharmacokinetic results, after single intravenous drip of antiangiotide following a single intravenous drip to tumor patients at a dose of 7.5 mg/m2 and 15 mg/m2 ,AUC0-135 and AUC0-150 was tested to be (2 067. 829 ± 384. 392), (9 858. 611 ± 804. 555 ) ng/( L·min), AUC0-∞ was ( 2 110. 049 ± 382. 736 ), ( 9 953. 023 ± 785. 602) ng/(L.min), Cmax was (22. 581± 6. 957), ( 153. 150 ± 21. 963) ng/mL and T1/2 was (9. 179 ± 2. 756), (7. 553 ±0. 366) min respectively. Therefore,these data confirmed that the ELISA method could specifically and reliably detect blood concen- trations of antiangiotide and be applied to related pharmaeokinetic research.
