摘 要:目的:建立测定血浆样品中昂丹司琼浓度的液相色谱-质谱定量分析方法,用于国产盐酸昂丹司琼口服溶液生物等效性研究。方法:20名男性健康志愿者随机交叉给药,分别单剂量口服盐酸昂丹司琼口服溶液(受试制剂)及盐酸恩丹西酮片(参比制剂),采用高效液相色谱-质谱法,电喷雾电离源选择性正离子检测受试者血浆中昂丹司琼的浓度,计算两者药代动力学参数及相对生物利用度。结果:2种制剂tmax分别为(1.65±0.46)h和(1.60±0.62)h,Cmax分别为(57.58±14.11)ng·mL-1和(53.01±16.24)ng·mL-1,2种制剂的t1/2分别为(3.50±0.80)h和(4.13±1.25)h,药时曲线下面积AUC(0→24)分别为(353.63±75.84)ng·h·mL-1和(326.02±104.49)ng·h·mL-1。结论:2种制剂生物等效,相对生物利用度为110.9%。Objectives:To establish an HPLC -MS method for determination of pharmacokinetic of ondansetron in human plasma, and to study the bioequivalenee of ondansetron hydrochloride oral solution. Methods: Twenty healthy male volunteers were orally administered with a randomized and single crossover dose of ondansetron hydrochloride oral solution ( test sample) and ondansetron hydrochloride tablets ( reference sample) 8 mg. The plasma ondansetron were quantified by HPLC -MS( SIM^+ ). The pharmacokinetics parameters and relative bioavailability were calculated using DAS 2.0. Results: The main pharmacokinetie parameters of test and reference preparation were as followed : tmax were (1.65 ± 0. 46 ) h and ( 1.60 ± 0. 62) h, Cmax were (57.58 ± 14. 11 )ng · mL^- 1 and (53.01 ±16. 24) ng· mL^- 1, t1/2were ( 3.50 ± 0. 80 ) h and ( 4. 13 ± 1.25 ) h, AUC (0-24) were ( 353.63 ± 75.84 ) ng· h· mL^- 1 and (326.02 ± 104. 49)ng· h· mL^-1. Conclusion:The results show that the two formulations are bioequivalent. The relative bioavailability of ondansetron hydroehloride oral solution is 110. 9%.
