Abstract

The pharmacokinetics of ceftazidime after a 1-g bolus dose were studied in 11 subjects, with creatinine clearances ranging from 113 to 6 ml/min. Concentrations of ceftazidime in serum were determined by microbiological assay. These data were fitted to a two-compartment open model, and pharmacokinetic parameters were calculated. Correlation of ceftazidime clearance with creatinine clearance was excellent (r = 0.99).

摘要

在11名肌酐清除率范围为113至6 ml/min的受试者中研究了1克头孢他啶大剂量推注后的药代动力学。通过微生物测定法测定血清中头孢他啶的浓度。将这些数据拟合到二室开放模型,并计算药代动力学参数。头孢他啶清除率与肌酐清除率的相关性极佳(r = 0.99)。
