Abstract: OBJECTIVE To study the dose effects on pharmacokinetics of m-Nif. METHODS 15 rabbits were divided into 3 groups receiving iv m-Ni f 05,1,and 2 mg/kg Plasma levels of m-Nif were determined with HPLC method. RESULTS The concentration-time data were fitted with 2-compartment model.The parameters were after iv l mg/kg:Vd=0.37L/kg,Tα/2=6.4min,Tβ/2=84.1min,AUC=94.1mg·min/L,CL=0.65L/(kg·h).No statistically significant diference was found in C1 and Tβ/2 between 3 dose groups.AUC (standardized to body weight)was correlated with doses. CONCLUSION m-Nif was distributed widely and eliminated at a fairly rapid rate in the rabbits.No dose-dependent pharmacokinetics was found after iv m-Nif 0.52mg/kg.
