摘要
目的:研究10例急性淋巴细胞白血病患儿应用大剂量甲氨蝶呤(MTX)的体内药动学参数,探讨最佳解救时间,并对其不良反应进行分析。方法:使用统一的治疗方案,采用荧光偏振免疫(FPIA)方法,监测一定时间的MTX血药浓度。结果:MTX体内药动学药时曲线符合一房室模型,其Cmax为(60.3±14.3)μmol·L-1;Ke为(0.11±0.02)h-1;Vd为(655.2±411.8)L;CL为(15.2±8.5)L·h-1;t1/2(ke)为(7.9±2.3)h;AUC0-10为(152.4±65.4)μmol·L-1·h;AUC0-∞为(157.2±73.7)μmol·L-1·h;MRT为(3.8±2.6)h。结论:开展小儿急性淋巴细胞白血病患儿使用大剂量甲氨蝶呤的体内药动学研究具有重要的临床意义。
OBJECTIVE To study the pharmacokinetics of methotrexate (MTX) in children with acute lymphocytic leukemia (ALL) treated by high dosage of MTX. METHODS The concentrations of MTX in serum was determined by EPIA. RESULTS The pharmacokinetic parameters such as Cmax was (60. 26 ± 14. 29)μmol· L^-1; Ke was (0. 11 ± 0. 02) h^- 1 ; Vd was (655.2 ± 411.8) L CL was (15.2 ± 8. 5 ) L · h^-1 ; t1/2(ke) was (7. 9 ± 2. 3) h; AUG0-10 was (152. 4 ± 65. 4)μmol · L^-1·h; AUG0-∞ was (157. 2 ± 73.7) μmol· L^-1·h;MRT was (3. 8 ± 2. 6)h. CONCLUSION The study provides useful data for HD-MTX-CF treatment and has important clinical significance.
