摘要: 目的: 研究盐酸氟桂利嗪分散片药代动力学及生物等效性。方法: 20名健康受试者按体重指数进行分层随机交叉服用盐酸氟桂利嗪试验制剂和参比试剂20 mg,采用高效液相色谱法测定盐酸氟桂利嗪的血药浓度。结果: 口服20 mg被试制剂与参比制剂后,盐酸氟桂利嗪AUC0-1,分别为424.27±74.01 和 410.25±72_56 μg·h-1·L-1;Cmax分别为67.02±14.89 和 67.45±15.68 μg·L-1;Cmax分别为2.90±0.42 和 2.98±0_47 h; t1/2ke分别为 9.73±3.15和8.89±3.08 h。试验制剂的相对生物利用度为(104.12±12.23)%。结论: 盐酸氟桂利嗪分散片和肢囊具有生物等效性。

Abstract: AIM: To study the bioequivalence be-tween flunarizine hydrochloride dispersible tablets and capsules in healthy volunteers. METHODS: A single dose of 20 mg flunarizine hydrochloride dispersible tablets and capsules were given to 20 healthy volunteers by a ran-domized,two way cross-over design. Plasma concentra-tions of flunarizine hydrochloride were determined by HPLC. RESULTS: The pharmacokinetic parameters after administration of flunarizine hydrochloride dispersible tablets and contrast flunarizine hydrochloride capsules (20 mg) were as follows: AUC0-1, 424.27±74.01 and 410.25±72.56 μg·L-1,C_67.02±14.89 and 67.45±15.68 μg·L-1,Tmax 2.90±0.42 and 2.98±0.47 h, and t1/2ke9.73±3.15 and 8.89±3.08 h,respectively. The relative bioavailability of the flunaiizine hydrochloride tablets was (104.12±12.23)%. CONCLUSION: Two formations of flunarizine hydrochloride are bioequivalent.
