摘要: 目的 观察司帕沙呈在慢性肾 衰患者血液进析时的药物动力学特征。方法 用高效液 相色讲法测定透析和非透析住院患者单剂量口服司帕沙星后血清和尿药物浓度,并计算药物动力学参数。结果 经PKNP-N1药代动力学软件模拟和计算,司帕沙星的药物动力学符合一级吸收二室开放模型,主要药动学参数:透析时T1/2(ka)=(1.25+0.57)h, T1/2(β)= (1188土4.13) h., Tpeak= (4.18+0.78) h, Cmax= (0.80+0.17) mg·L-1,AUC0~∞=(6.90土3.25)mg·h·L-1,尿中24h原形药物排除率为(8.98士3.92)%;未透析时T1/2(ka)= (1.12+0.42) h, T1/2(β)=(15.93+5.20) h, Tpeak =(3.88+0.75) h,Cmax=(0.69+0.37) mg·L-1, AUC0~∞=(10.05+4.13) mg·h·L-1,尿中24h原形药物排出率为(10.S8+5.64)%。结论 司帕沙星在慢性肾衰患者血液透析时消除加快。

Abstract: Aim To observe the effect of hemodialysis on pharmacokinetics of sparfloxacin in the patients contracting chronic renal failure. Methods Sparfloxacin concentrations in serum and urine of hemodialysis and non-dialysis patients were measured with a high performance liquid chromatography method after administration a single oral dose of 200 mg sparfloxacin. The pharmacokinetic parameters were computed with the program PKBP-N.Results The main pharmacokinetic parameters in hemodialysis group were T1/2(ka)= (1.25士0.57) h,T1/2(β)= (11.88士4.13) h,Tpeak = (4. 18士0.78) h, Cmax =(0.80+0.17) mg·L-1 and AUC0~∞= (6. 90土3.25) mg·h·L-1,while in non-dialysis group were T1/2(ka)= (1.12+0.42) h, T1/2(β)= (15.93土5.20) h, Tpeak =(3. 88土0.75) h, Cmax= (0. 69+0.37) mg·L-1, AUC0~∞= (10.05士4.13) mg·h·L-1. The original sparfloxacin discharge rats in urine within 24 h were (8. 98士3.92)% and (10. 58土5. 64) % separately. Tr2q) and AUC in hemodialysis group were markedly lower:than in non-dialysis group (P<0. 05).Conclusion The pharmacokinetics of sparfloxacin in patients contracting chronic renal failure is not changed by hemodialysis.
