摘  要:目的:研究2种利巴韦林制剂的生物等效性。方法:采用随机交叉试验设计,采用液-质联用法测定20例男性健康志愿者单剂量口服150mg利巴韦林受试泡腾片(受试制剂)及利巴韦林受试颗粒(参比制剂)后利巴韦林的血药浓度,并计算相关药动学参数。结果:利巴韦林受试制剂与参比制剂的主要药动学参数分别为:t1/2(44.00±8.75)、(44.89±10.44)h,tmax(1.0±0.7)、(0.8±0.2)h,cmax(424.12±133.03)、(406.09±108.22)ng.mL-1,AUC0~108h(4997.59±1322.31)、(4921.16±1030.61)ng.h.mL-1。以AUC0~108h计算,利巴韦林受试制剂平均相对生物利用度为(105.4±37.4)%。统计学结果表明,2种制剂主要药动学参数t1/2、cmax、tmax、AUC0~108h均无显著性差异。结论:本方法专属、灵敏、准确,利巴韦林2种制剂在人体内具有生物等效性。OBJECTIVE: To study bioequivalence of 2 kinds of ribavirin preparations. METHODS: In randomized crossover de- sign, the plasma concentration of ribavirin in 20 healthy volunteers was determined by LC-MS after oral administration of Ribavirin ef- fervescent tablet 150 mg (test preparation) and Ribavirin granules (reference preparation), and the major pharmacokinetic parameters were calculated. RESULTS:The main pharmacokinetic parameters of test preparation vs. reference preparation were as follows: tmax (44.00 ±8.75 )h vs. (44.89 ± 10.44)h; t1/2(1.0 ± 0.7 ) h vs. (0.8 ± 0.2) h; Cmax(424.12 ±133.03)ng. mL^-1 vs. (406.09± 108.22)ng. mL^-1; AUC0-108 h (4 997.59 ± 1 322.31) ng. h. mL^-1 vs. (4 921.16 ± 1 030.61 ) ng. h. mL^-1. The relative bioavailability of test tablet was (105.4 ±37.4)% by AUC0-108 h. The statistical result showed that there was no significant difference between 2 preparations in the t1/2, Cmax, tmax, AUC0-108h. CONCLUSION: The method is specific, sensitive and accurate. The two preparations are bioequivalent.
