摘要
目的:评价布洛芬软胶囊与布洛芬胶囊的人体生物等效性。方法:20名健康志愿者随机交叉口服单剂量(400 mg)布洛芬软胶囊与参比制剂布洛芬胶囊,采用高效液相色谱法测定血浆中布洛芬的血药浓度。结果:受试制剂与参比制剂的Tmax分别为(2.78±0.57)和(2.83±0.47)h,Cmax分别为(34.94±6.58)和(32.77±5.50)μg·mL-1,t1/2分别为(2.49±0.65)和(2.39±0.58)h,AUC0~1分别为(148.49±26.44)和(147.57±36.18)μg·h·mL-1,AUC0-∞分别为(157.28±27.96)和(157.43±42.47)μg·h·mL-1,以AUC0-∞计算,布洛芬软胶囊的相对生物利用度平均为(103.5±18.1)%。结论:布洛芬软胶囊与参比制剂布洛芬胶囊生物等效。
Objective: To evaluate the relative bioavailability of ibuprofen soft capsules (test) versus hard capsules (reference). Methods: The blood ibuprofen concentrations from 20 healthy male volunteers, who received a single crossover dose of test and reference ibuprofen 400 mg, were measured by HPLC. Results: The pharmacokinetic profiles of test and reference ibuprofen were Cmax (34.94 ± 6.58)vs. (32.77 ±5.50)/μg·mL^-1, Tmax(2.78 ±0.57)vs. (2.83 +0.47)h, AUC0-t(148.49 ± 26.44)vs.(147.57±36.18)/μg·h·mL^-1, AUC0-∞ (157.28±27.96)vs. (157.43±42.47)/μg·h·mL^-1 and t1/2 (2. 49 ± 0.65) vs. (2.39 ± 0.58 ) h, respectively. The relative bioavailability of the test ibuprofen was( 103.5 ± 18.1 )%. Conclusion: The test ibuprofen was bioequivalent to the reference ibuprofen.
