Objective: The pharmacokinetics of cefetamet pivoxil was determined after a single 500mg oral dose given to twelve male volunteers. Methods: The concentrations of drug-serum samples were measured by high performance liquid chromatography (HPLC). Results: The results showed that the serum concentration-time profile conformed to an one-compartment open model. The maximum serum level was 2.17mg/L
and was attained ·2.79h after administration. The mean serum elimination half-life was 2.34h. The AUC was 18.96 (mg/L)h. Conclusion: The serum concentration after a single dose of 500mg is above the MIC for most of the commonly encountered pathogens. The elimination half-life is long enough
so cefetamet pivoxil may be administrated twice a day.
