摘要: 目的: 研究氯法拉滨注射液单剂量及多剂量静脉滴注的人体药动学过程。方法: 4例白血病患者单剂量恒速静脉滴注氯法拉滨注射液 52 mg·m-2·d-1 ,单剂量试验结束后进入多剂量给药试验, 52 mg·m-2·d-1 ,连续给药 5 d。采用高效液相色谱串联质谱法测定血浆及尿液中氯法拉滨的浓度,并采用DAS药动学软件对试验数据进行处理,求算有关药动学参数。结果: 4例受试者单剂量静脉滴注氯法拉滨注射液后,主要药动学参数分别为Cmax(414±205) μg/L,tmax(3.0±1.4) h,t1/2z(4.4±2.0) h,AUC0-t(2475±659) μg·h·L-1,AUC0-∞(2566±606) μg·h·L-1,CLz(21.2±5.1) L·h-1·m-2,Vz(142±97) L/m2,MRT(0-t) (6.3±2.2) h,Zeta(0.18±0.07) h-1,24 h 平均尿液累积排泄率为(39.53±20.98)%。52 mg·m-2·d-1静脉滴注氯法拉滨注射液,连续给药5 d,第5日达稳态,主要药动学参数为Cmax(581±126) μg/L,tmax(2.0±0.8) h,t1/2z(6.4±3.1) h,AUC0-t(2451±349) μg·h·L-1,AUC0-∞(2603±409) μg·h·L-1,CLz(20.4±3.7) L·h-1·m-2,Vz(187±80) L/m,Zeta(0.13±0.05) h-1,MRT(0-t) (5.1±1.8) h,Css(102.14±14.53) μg/L,蓄积因子R(1.04±0.28),血药浓度波动度DF(576.26±226.89)%。结论: 氯法拉滨注射液静脉滴注给药 52 mg·m-2·d-1 ,连续给药 5 d,药物在体内无蓄积,安全性好。

Abstract: AIM: To investigate the pharmacokinetics of Clofarabine for injection with a single and multiple dose administration in patients with acute leukemia.METHODS: 4 patients with acute leukemia received a single dose intravenous of 52 mg·m-2·d-1, and then they are repeatedly administrated with 52 mg·m-2·d-1 Clofarabine for 5 days.The concentrate of Clofarabine in plasma and urine were determined by HPLC-MS/MS.DAS pharmacokinetics software was used for data process and calculation of pharmacokinetic parameters.RESULTS: The main pharmacokinetic parameters of Clofarabine after single dose of 52 mg·m-2·d-1 Clofarabine for injection were as follows: Cmax(414±205) μg/L,tmax(3.0±1.4) h, t1/2z(4.4±2.0) h,AUC0-t(2475±659) μg·h·L-1, AUC0-∞(2566±606) μg·h·L-1, CLz(21.2±5.1) L·h-1·m-2, Vz(142±97) L/m, MRT0-t(6.3±2.2) h, Zeta(0.18±0.07) h-1, the 12 h cumulative urine excretion rate was (39.53±20.98)%, the main pharmacokinetic parameters of Clofarabine after 52 mg·m-2·d-1 for 5 days were as follows: Cmax(581±126) μg/L, tmax(2.0±0.8) h, t1/2z(6.4±3.1) h, AUC0-t(2451±349) μg·h·L-1, AUC0-∞(2603±409) μg·h·L-1, CLz(20.4±3.7) L·h-1·m-2, Vz(187±80) L/m, Zeta(0.13±0.05) h-1, MRT0-24 h(5.1±1.8) h, Css(102.14±14.53) μg/L,the accumulation coefficients R was (1.04±0.28), the fluctuation coefficients of plasma concentration DF was (576.26±226.89)%.CONCLUSION: No accumulation is detected when 52 mg·m-2·d-1 Clofarabine for injection has been administrated for 5 days, it was safe.
