摘要 为了解硫酸头孢喹肟在牛体内的动力学特征,对4头健康牛进行单剂量肌注硫酸头孢喹肟(1.0 mg/kg),血浆样品经乙腈沉淀血浆蛋白。用反相高效液相色谱法测定牛血浆中硫酸头孢喹肟的浓度,3P97药动学计算软件处理血浆药物浓度-时间数据。结果表明,健康牛肌注硫酸头孢喹肟的血药浓度-时间数据符合一级吸收二室开放模型,主要动力学参数T1/2α=(0.52±0.03)h,T1/2β=(6.98±0.80)h,V/F=(3.30±0.023)L/kg,t1/2Ka=(0.37±0.01)h,AUC=(17.57±1.35)μg/(h.mL),CL(s)=(1.35±0.40)L/h,Tpeak=(0.74±0.02)h,Cmax=(3.00±0.11)μg/mL。说明硫酸头孢喹肟在牛体内分布广,吸收迅速,达峰时间短,半衰期较长。
