摘要
目的研究A771726在大鼠体内的药代动力学过程。方法单剂量口服给药3个剂量的A771726,根据大鼠体内血药浓度经时过程,计算相应的药代动力学参数。结果A771726(3、6、12mg/kg)的血药经时过程均符合一级吸收的一房室模型,其主要药动学参数T1/2Ka(h):3.91±3.43、5.63±2.07、6.73±1.67;T1/2Ka(h):17.45±10.79、9.68±4.65、7.63±1.39;AUCm。)(mg/L·h^-1):163.83±17.88、447.88±148.60、843.72±175.41;Cmax(mg/L):7.05±1.17、24.00±1.87、39.93±3.90;Tmax(h):8.00±0.00、6.67±2.06、8.00±0.00;MRT(0-m)(h):19.87±4.25、19.54±1.11、19.29±2.47。结论单剂量口服A7717263个剂量组的药物代谢均成线性关系,其血药浓度-时间曲线符合一级吸收的一房室模型。
Objective To study the pharmacokinetics of A771726 in rats. Methods A single oral dose of A771726 (3, 6, 12 mg/kg)was performed in SD rats, then the corresponding pharmacokinetic parameters based on the time process of blood drug concentration were calculated. Results The blood plasma CoL curve of A771726 conformed to one compartment model of the first order absorption. The main pharmacokinetie parameters of A771726(3, 6, 12 mg/kg) were T1/2Ka ( h ) : 3.91 ± 3.43, 5.63 ± 2.07, 6. 73± 1.67 ; T1/2Ka ( h ) : 17.45 ± 10. 79, 9.68 ± 4.65, 7.63±1.39; AUC(0-m)(mg·h/L): 163.83±17.88,447.88±148.60, 843.72±175.41; Cmax(mg/L): 7.05 ±1. 17, 24.00±1.87, 39.93 ±3.90; Tmax (h): 8.00±0.00, 6.67±2.06, 8.00±0.00; MRT(0-m)(h): 19. 87 ±4.25, 19.54 ± 1. 11 , 19. 29±2.47. Conclusion The metabolism of A771726 following oral administration accords with the linear relation, and its blood plasma Cot curve consists with the first order kinetics of one compartment model.
