摘要
目的研究盐酸帕洛诺司琼注射液在健康受试者体内的药动学过程。方法36名健康志愿者随机分成3组,每组12人,男女各半,分别单剂量静脉注射盐酸帕洛诺司琼0.25、0.5和0.75mg,血浆中帕洛诺司琼浓度用HPLC-MS/MS法测定,以DAS2.1.1软件计算药动学参数。结果单剂量静脉注射盐酸帕洛诺司琼注射液0.25、0.5和0.75mg后主要药动学参数如下:t1/2分别为(43.9±10.7)、(44.3±9.8)、(43.2±13.5)h,Cmax分别为(4.18±2.35)、(8.80±6.83)、(12.7±11.3)μg·L^-1,AUC0~t分别为(37.9±11.1)、(69.9±22.5)、(108.4±40.3)μg·h·L^-1,AUC0~∞分别为(41.6±12.2)、(74.8±24.1)、(117.7±48.1)μg·h·L^-1,CL分别为(6.6±2.1)、(7.5±2.9)、(7.3±2.7)L·h^-1。结论中国健康受试者单剂量静脉注射盐酸帕洛诺司琼后,在0.25~0.75mg剂量呈线性药动学特征,本试验建立的测定方法简便、灵敏、准确。
Objective To study the pharmacokinetics ofpalonosetron hydrochloride for intravenous administration in healthy volunteers. Methods Thirty-six healthy volunteers were randomly divided into 3 groups (12 in each group). A single dose of 0.25, 0.5 and 0.75 mg palonosetron hydrochloride was administered to each group, respectively. The concentration of palonosetron hydrochloride in human plasma was detemined by HPLC-MS/MS. The main pharmacokinetic parameters were calculated with DAS Ver 2.1.1. Results The main parameters of a single dose of 0.25, 0.5 and 0.75 mg palonosetron hydrochloride were as follows: t1/2 was (43.9 ± 10.7), (44.3±9.8) and (43.2 ± 13.5) h; Cmax was (4.18 ± 2.35), (8.80 ± 6.83) and (12.7±11.3)μg·L^-1; AUC0-t was (37.9±11.1), (69.9±22.5) and (108.4±40.3)μg·h·L^-1; AUC0-∞ was (41.6±12.2), (74.8±24.1) and (117.7 ±48.1) μg·h·L^-1; CL was (6.6±2.1), (7.5 ± 2.9), (7.3 ± 2.7) L·h^-1, respectively. Conclusion The process of palonosetron hydrochloride in 0.25 - 0.75 mg fits the linear dynamic feature. This determination method for palonosetron is simple, sensitive and accurate.
