摘要: 目的: 研究两种尼麦角林片剂在健康人体的生物等效性。方法: 20 名健康志愿者随机双交叉、单剂量口服受试制剂尼麦角林片和参比制剂尼麦角林片, 剂量均为20 mg, 剂间间隔为1 周。其中尼麦角林在体内的最主要的代谢产物为10α-甲氧基-9,10-二氢麦角醇(MDL), 故用LC-MS 内标法测定血浆中MDL 浓度, 应用DAS 药动学程序进行有关药代动力学参数、相对生物利用度计算, 并根据新药审批指导原则评价两种制剂的生物等效性。结果: 表明该分析方法专属性强, 方法简便。受试制剂与参比制剂的药代动力学参数, 尼麦角林:tmax 分别为(3.3±0.9) 和(3.2±0.7) h, t1/2 分别为(12.9±4.0) 和(12.8±2.4) h, Cmax分别为(23±6) 和(22±6) μg/L,AUC0-t 分别为(291±51) 和(282±44) μg·L-1·h,AUC0-∞分别为(316±50) 和(299±46) μg·L-1·h 。尼麦角林的相对生物利用度为(104±17)%。结论: 两种尼麦角林片剂在健康人体具有生物等效性。

Abstract: AIM: To study the pharmacokinetics and bioequivalence of nicergoline tablets in healthy volunteers. METHODS: A single oral dose (20 mg test or reference formulation)was given to 20 healthy volunteers according to an open randomized crossover design.10α-methoxy-9, 10-dihydrolysergol(MDL) is a majormetabolite of nicergoline, the concentration of MDL in plasma was determined by LC-MS.The pharmacokinetics parameters were calculated and the bioavailability and bioequivalence of two formulations were evaluated by DAS program. RESULTS: The main pharmacokinetic parameters of nicergoline tablets were as follows:tmax were (3.3±0.9) and (3.2±0.7) h, t1/2 were (12.9±4.0) and(12.8±2.4) h, Cmax were (23±6) and (22±6) μg/L;AUC0-t were (291±51) and(282±44) μg·L-1·h;AUC0-∞ were (316±50) and (299±46) μg·L-1·h.The relative bioavailability of two formulations was (104±17)%. CONCLUSION: The two nicergoline formulations are bioequivalent.

Key words: nicergoline, 10α-methoxy-9,10-dihydrolysergol, relative bioavailability, bioequivalence, LC-MS
