A single 1.0-g dose of cefaclor administered to patients with stable end stage renal disease whose creatinine clearances were <5 ml/min produced a mean peak serum concentration of 48.3 +/- 19.8 mug/ml. The half-life was 2.3 +/- 0.3 h. Hemodialysis shortened the half-life of a similar dose to 1.6 +/- 0.3 h. Approximately one-third (340 mg) of the administered drug was recovered in the dialysate. Multiple doses of 500 mg every 6 h between hemodialysis sessions produced effective serum concentrations and no bioassay evidence of drug accumulation.
给肌酐清除率<5ml/分钟的稳定终末期肾病患者单次服用1.0g头孢克洛,血清平均峰浓度为48.3±19.8μg/ml。半衰期为2.3±0.3小时。血液透析将相似剂量的半衰期缩短至1.6±0.3小时。约三分之一(340mg)的给药剂量可在透析液中回收。在血液透析期间每6小时多次给予500mg药物可产生有效的血清浓度,且生物测定未发现药物蓄积的证据。
