摘要
目的:研究2种吗替麦考酚酯胶囊的人体生物等效性。方法:18名受试者随机、交叉、单剂量分别口服吗替麦考酚酯胶囊受试制剂(国产)和参比制剂(进口)1000mg。血药浓度采用反相高效液相色谱法测定;计算药动学参数并评价生物等效性。结果:受试制剂与参比制剂的主要药动学参数Cmax分别为(26.38±9.55)、(25.84±12.08)μg·mL-1,tmax分别为(0.79±0.40)、(0.94±0.59)h,t1/2分别为(18.01±7.65)、(15.62±8.50)h,AUC0~48分别为(54.69±15.58)、(51.68±12.36)μg.h.mL-1,AUC0~∞分别为(61.10±17.06)、(57.99±17.21)μg.h.mL-1。受试制剂的相对生物利用度为(107.22±25.39)%。结论:国产与进口吗替麦考酚酯胶囊生物等效。
OBJECTIVE: To study the bioequivalence of the domestic and the imported mycophenolate mofetil capsules in human body. METHODS: A single dose of 1 000mg domestic mycophenolate mofetil capsules (trial) or its reference capsule (imported ones) were given to each volunteer in a randomized double cross over design. The plasma concentration was determined by RP - HPLC, The pharmacokinetic parameters of two preparations were calculated and the bioequivalence of which was evaluated. RESULTS: The main pharmacokinetic parameter of the trial vs. the reference preparations of mycophenolate mofetil capsules were as follows: Cmax: (26.38±9.55) versus (25.84+ 12.08) μg·mL^1; tmax(0.79±0.40)h versus (0.94±0.59) h;t 1/2: (18.01±7.65)h versus (15.62± 8.50)h;AUC0-48: (54.69±15.58) versus (51.68±12.36)μg·h·mL^1 ; AUC0-∞ (61.10±17.06) versus (57.99±17.21) μg·h·mL^1. The relative bioavailability of the trial preparation was (107.22± 25.39) %. CONCLUSION: The results suggest that the two formulations are bioequivalent.
