Abstract: OBJECTIVE To determine pharmacokinetics of tinidazole in patients with lung infection.METHODS The concentration of tinidazole in patients'serum was determined by a RP-HPLC method.Metronidazole was being internal standard and a mobile phase of wateracetonitrile-acetic acid(80:20:0 1) were used.There was a good liner relation within the range of 1~50mg/L and the determination limit was 0 1mg/L.Of these patients,5 males and 2 females,were driped intravenously 400mg of tinidazole within 90min.RESULTS The results suggested the pharmacokinetics of administrated tinidazole could be described by a linear two-compartment model.The pharmacokinetic parameters were T1/2α=(2.42±1.75)h,T1/2β=(14.20±4.00)h,AUC0~∞=(219.0±83.9)mg.h/L,Vc=(26.58±11.75)L. CONCLUSIONS There was marker difference for pharmacokinetics of tinidazole among the 7 patients.
