摘 要:目的建立测定血浆中国产磷酸奥司他韦胶囊(商品名:军科奥韦胶囊)活性代谢产物浓度的LC-MS/MS方法,研究军科奥韦胶囊在中国健康男性志愿者的主要药动学参数以及与参比制剂的生物等效性。方法采用2制剂双周期交叉试验设计,24名受试者分别单剂量口服受试制剂军科奥韦胶囊和达菲参比制剂,用LC-MS/MS测定其活性代谢产物的含量,所得参数经BAPP2.0软件计算药动学参数并考察生物等效性。结果口服参比制剂及受试制剂后,其活性代谢产物的ρmax分别为(625.17±147.76)和(633.57±115.28)μg.L-1;tmax分别为(4.5±1.0)和(4.5±1.2)h;t1/2分别为(8.13±1.13)和(7.79±0.89)h;MRT分别为(12.09±1.38)和(11.95±1.03)h;AUC0-τ分别为(7247.02±1720.33)和(7506.16±1454.36)μg.h.L-1;AUC0-∞分别为(7428.75±1793.94)和(7659.99±1477.83)μg.h.L-1;受试制剂对参比制剂的相对生物利用度为(105.8±17.7)%。结论利用方差分析及双单侧t检验分别对受试和参比制剂进行生物等效性评价,军科奥韦胶囊和已上市的达菲胶囊制剂具有生物等效性。OBJECTIVE To evaluate the bioavailability and bioequivalence of oseltamivir capsule in Chinese health male volunteers.METHODS A randomized,two period,two treatment,two sequence crossover bioequivalence trial was designed,24 Chinese health volunteers were randomly divided into two groups,each group was orally given single dose oseltamivir phosphate (tamifla) or test capsule.The active metabolite oseltamivir carboxylate of oseltamivir in the plasma were determined by liquid chromatographic-tandem mass spectrometric (HPLC-MS/MS) method.The pharmacokinetics parameters and relative bioavailability were calculated to evaluate the bioequivalence of test capsule and tamifla.RESULTS ρmax of the active metabolite were (625.17±147.76) and (633.57±115.28)μg·L-1 for test capsule and tamifla respectively,tmax were (4.5±1.0) and (4.5±1.2)h,t1/2β were (8.13±1.13) and (7.79±0.89)h,MRT were (12.09±1.38) and (11.95±1.03)h,AUC0-24 were (7 247.02±1 720.33) and (7 506.16±1 454.36) μg·h·L-1.Compared with the reference of tamifla capsule,the bioavailability F0-24 of the test capsule was (105.8±17.7)%.The main pharmacokinetics parameters of AUC0-24,ρmax and tmax showed no statistically significant difference between the two capsules.CONCLUSION The test capsule and tamifla capsule are bioequivalent.
