摘    要:研究氟苯尼考磺酸盐在肉鸡体内的血药浓度及药动学特征。将12只健康三黄肉鸡,单次肌肉注射推荐治疗剂量(20mg/kg)的自制2%氟苯尼考磺酸盐。采用高效液相色谱法测定血浆药物浓度,所得数据用3P97药动软件进行分析后发现,血药浓度和时间关系符合一级吸收一室模型,选择的权重为1/C。主要药动学参数为T1/2kα:(0.28±0.04)h,T1/2Ke:(2.06±0.06)h,Cmax:(4.17±0.12)μg/mL,Tmax:(0.92±0.09)h,AUC:(16.89±0,35)μg/mL,V/F(c):(3.52±0.13)L/kg,CL/F(s):(1.19±0.03)L/(kg·h),Ke:(0.34±0.01)/h,kα:(2.57±0.37)/h,A:(6.56±0.38)μg/mL。结果提示,氟苯尼考磺酸盐在肉鸡体内具有吸收迅速,分布广泛、峰浓度较高以及消除较快的动力学特征。

Abstract:This experiment was conducted to study the pharmacokinetics of florfenicol sulfonate in broiler chickens plasma. Twelve broiler chickens were, used to give single intramuscular injection of florfenicol sulfonate at a dosage of 20 mg/kg. The concentrations of florfenicol sulfonate in plasma were determined by HPLC. The pharmacokinetics parameters were calculated by 3P97 computer program and fitted a one - compartment open model with weight by 1/C. The main parameters of florfenicol sulfonate in broiler chickens were as follows:T1/2 kct: (0.28±0.04) h,T1/2 Ke: (2.06 ±0.06) h, Cmax: (4.17±0.12)μg/mL, Tmax: (0.92 ±0.09) h,AUC: (16.89±0.35)μg/mL, V/F(c) : (3.52±0. 13)L/kg, CL/F(s) : (1. 19±0.03)L/(kg· h),Ke: (0, 34 ± 0.01 )/h,kα: (2.57 ±0.37)/h,A: (6.56±0.38) μg/mL. The results showed that the distribution of florfenieol sulfonate was rapid and wide in the broiler chickens, the concentration of plasma was high and elimination was quick.
Keywords:florfenicol sulfonate florfenicol pharmacokinetics broiler chickens
