摘  要:目的研究2种盐酸舍曲林制剂的人体生物等效性。方法采用双周期随机交叉设计试验,22名健康男性志愿者单剂量口服盐酸舍曲林口服液(受试制剂)或盐酸舍曲林片(参比制剂)50mg,以高效液相色谱-质谱联用法测定血药浓度。结果受试制剂与参比制剂的t1/2分别为(27.3±5.2)、(26.3±3.0)h,Cmax分别为(9.56±2.49)、(9.43±2.91)μg·L-1,tmax分别为(5.18±1.47)、(6.00±1.07)h,AUC0~108分别为(329±112)、(297±111)μg.h·L-1,AUC0~∞分别为(354±127)、(316±122)μg.h.L-1。经方差分析和双单侧t检验,主要药动学参数无差异,但tmax存在差异;受试制剂的相对生物利用度为(115.5±26.7)%。结论2种盐酸舍曲林制剂具有生物等效性。OBJECTIVE: To study the bioequiavailability of two sertraline hydrochloride formulations in healthy volunteers.METHODS: A randomized, crossover study of 22 healthy volunteers receiving single oral dose of 50mg sertraline hydrochloride solution(test preparation) or sertraline hydrochloride tablets(comparator preparation) was conducted and the blood concentrations determined by LC/ MS/ MS.RESULTS: The pharmacokinetic parameters for the test sertraline and the comparator sertraline were as follows:t 1/2 were (27.3± 5.2)h and (26.3± 3.0)h,respectively;Cmax were(9.56± 2.49)μg · L^ -1 and (9.43± 2.91) μg · L^-1, respectively; tmax were(5.18± 1.47) h and(6.00± 1.07) h, respectively; AUC0-108 were(329 ± 112) μg · h · L ^-1 and (297± 111) μg · h · L^-1, respectively; AUC0-∞ were(354± 127) μg · h · L^ -1 and (316± 122) μg · h · L^- 1, respectively.There were no significant differences in main pharmacokinetics parameters between the 2 preparations, except in tmax from analysis of variance and one- side & two- sides t tests.The relative bioavailability of the test sertraline was(115.5 ± 26.7) %. CONCLUSION :These two sertraline hydrochloride formulations are bioequivalent.
