Objective To investigate the pharmacokinetics of cephapirin sodium in healthy volunteers.Methods Twelve healthy volunteers were enrolled and ad ministered with single doses of 0.5,1.0,4.0 g or multiple doses of 1.0 g cephapirin sodium injection by intravenous drip infusion.The concentrations of cephapirin in human plasma and urine were determined by HPLC-MS/MS.The main pharmacokinetic parameters were calculated with WinNonLin 6.3 software. Results The main pharmacokinetic parameters of cephapirin after single dose of 0.5,1.0,4. 0 g and 1.0 g multiple dose cephapirin sodium injection were as follows:Cmaxwere (34.86 ±6.93),(74.77 ±24.23),(319.0 ±44.5),(89.26 ±28.04)μg/mL,AUC0-twere (12.86 ±3.46),(28.31 ±7.46),(163.21 ±34.57),(27.30 ±7.22)μg/(mL·h),t1/2were (0.55 ±0.21),(0.72 ±0.22),(0.71 ±0.27), (0.72 ±0.25),accumulative urine excretion rate of 8 h(1 g)was (44.9 ±12.66)%.Conclusion The process of cephapirin in the dosage range of 0.5 ~4.0 g show linear dynamic feature.There is no accumulation after multiple dosing.Cephapirin sodium was much eli minated from urine in parent drug.
