There were no significant differences in the time-kill curves of the two forms against the four strains at three concentrations. At drug concentrations of 2×MIC and 4×MIC, the bacterial count of all the strains decreased from 6 log CFU/mL to around 4 log CFU/mL. The bactericidal efficacies of the two agents were generally similar in the pharmacokinetics model of simulated intravenous drug administration of 1 g q8h. Only the PD parameter of bactericidal rate (KR) for ATCC 29213 and the area difference between the drug bactericidal curve and the bacterial growth control curve (IE) for ATCC25922 were statistically different. The KR and IE of the locally produced form were 0.73± 0.10 logCFU·h/mL and 83.73± 12.69 logCFU·h/mL, respectively, while the KR and IE of the branded form were 1.19± 0.07 logCFU·h/mL and 104.02± 16.28 logCFU·h/mL, respectively.Conclusion: The in-vitro antibacterial effect of locally produced cefuroxime sodium against Staphylococci and E. coli is comparable to that of branded cefuroxime sodium.Keywords: cefuroxime sodium, pharmacokinetics/pharmacodynamics, time-kill curves, in vitro |
