摘要 目的:研究国产与进口替米沙坦片的人体生物等效性.方法:20名健康男性志愿者随机交叉单剂量(80mg)口服受试制剂(国产)或参比制剂(进口),采用色谱-质谱法测定血药浓度,计算药动学参数和相对生物利用度。结果:受试制剂与参比制剂的Cmax分别为(534.2±314.3)、(540.7±314.1)μg/L,tmax分别为(1.3±0.8)h、(1.3±0.6)h,AUC.,9。分别为(3038.1±1997.9)、(3138.1±2124.7)(ug·h)/L,t1/2分别为(20.7±5.3)h、(21.3±6.6)h;受试制剂的相对生物利用度为(100.0±13.9)%。结论:国产与进口替米沙坦片具有生物等效性。 OBJECTIVE: To cvaluate the bioequivalence of domestic telmisartan tablets and imported ones. METHODS: 20 volunteers were randomly divided into 2 groups(domestic and imported). A single oral dose of 80mg telmisartan were given to each volunteer in the open random crossover study. Telmisartan serum concentrations were determined by HPLC - MS. Pharmacokinetic parameters and relative biosvailability were calculated. RESULTS- Cmax A UCo-96 and t1/2 of the imported tablets were(540.7±314.1)μg/L, (1.3±0.6)h, (3 138.1±2 124.7) (μg · h)/L, (21.3± 6.6)h, respectively, while the same parameters of the domestic tablets were (534.2± 314.3)μg/L, (1.3± 0.8)h, (3038.1 ± 1 997.9) (μg . h)/L, and(20.7± 5.3) h, respectively. The relative bioavailability of domestic tablets was (100.0 ±13.9)%. CONCLUSION: Domestic telmisartan tablets and imported ones have bloequivalence.
