摘要
目的研究利巴韦林注射液在大鼠体内的药代动力学,并考察利巴韦林的红细胞蓄积情况。方法采用反相HPLC法测定了大鼠静脉注射利巴韦林注射液后利巴韦林的血药浓度,使用3p87药代动力学软件计算其药代动力学参数。结果利巴韦林注射液在大鼠体内符合二室模型,主要的药动学参数如下:T1/2(α)为(10.82±2.66)min,T1/2(β)为(180.0±27.69)min,AUC为(1109.0±212.0)mg·L-1·min,CL(s)为(0.032±0.009)kg·L-1·min-1。结论利巴韦林在红细胞中有大量蓄积。
Aim To study the pharmacokinetics of Ribavirin Injection in rats and the accumation in erythrocyte. Methods The concentration of Ribavirin in plasma of rats after i. v. administration of Ribavirin Injection was determined by RP - HPLC method and the plasma concentration - time curve was plotted. The main pharmacokinetic parameters of Ribavirin were obtained. Results Ribavirin Injection in rats fits the two - compartment model and the main pharmcokinetic parameters of Ribavirin are as follows : T 1/2 (α) ( 10.82 ± 2. 658 ) min ; T 1/2 (β) ( 180.0 ± 27. 69) min ; AUC ( 1 109 ± 212.0 ) mg · L^- 1 . min; CL (s) (0. 032 ± 0.009 ) kg · L^- 1 . min^ - 1 respectively. Conclusion The accumulation of Ribavirin in erythrocyte is generous.
