Abstract:
Aim To investigate the difference in pharmacokinetics between gatifloxacin mesylate(GATM) and gatifloxacin(GAT) in SD rats in vivo.Method The plasma concentration-time courses of GAT in rats were measured by HPLC method after a single oral dose of GATM and GAT,and the pharmacokinetic parameters were estimated by program 3p97 software.Results The results shown that both of GATM and GAT plasma concentration-time courses were best fitted to two-compartment models after a single oral dose(GATM 23.43 mg?kg~(-1)and GAT 20 mg?kg~(-1),respectively).The major average pharmacokinetic parameters of GATM were as follwing: T_(2)?: 9.13 h,AUC: 15.05 mg?L~(-1)?h,C_(max): 4.41 mg?L~(-1),and T_(max): 0.5 h,respectively.On the other hand,the pharmacokinetic parameters of GAT were as follwing: T_(2)?:10.70 h,AUC:13.84 mg?L~(-1)?h,C_(max):4.25 mg?L~(-1),T_(max):0.5 h,respectively.Conclusion Under the equi-mole dose condition treated as above,both of pharmacokinetic characters between GATM and GAT were not significantly differences in rats
