摘要 目的:研究健康人体单剂量口服盐酸氨溴索分散片的药动学。方法:采用双周期交叉自身对照试验方法,18例健康志愿者单剂量口服盐酸氨溴索分散片和普通片各90mg,采用反相高效液相色谱法测定血浆中盐酸氨溴索浓度,计算并比较两者的主要药动学参数。结果:盐酸氨溴索分散片和普通片在健康志愿者血浆中的Tmax分别为(1.77±0.39)和(2.02±0.38)h;Cmax分别为(240.04±98.88)和(247.34±90.13)ug·L^-1; t1/2分别为(7.40±1.63)和(7.12±1.56)h;AUC0-36h分别为(1556.22±474.00)和(1633.89±402.03)ug·h·L^-1;AUC0~∞分别为(1607.13±489.33)和(1690.79±436.43)ug·h·L^-1。除Tmax外,盐酸氨溴索分散片和普通片各主要药动学参数间均无统计学差异(P〉0.05)。结论:盐酸氨溴索分散片与普通片相比,具有起效快的特点。 Objective: To study the pharmacokinetic profile of ambroxol hydrochloride dispersible tablets. Methods: In an open label, randomized, two period, cross-over and self control clinical tri- al, 18 health volunteers were administered with a single crossover dose of ambroxol dispersible tablet or ambroxol tablet (90 mg each). The plasma levels of ambroxol were measured by reversed-phase high performance liquid chromatography (RP-HPLC). Pharmacokinetic parameters were analyzed by DAS2.0 software. Results: The pharmacokinetic parameters of ambroxol dispersible tablets and ambroxol tablets were as follows : Tmax ( 1. 77 ± 0.39 ) vs. ( 2. 02 ± 0. 38 ) h ; Cmax ( 240.04 ± 98.88 ) vs. ( 247.34 ± 90. 13 ) ug·L^-1, AUC0-36 h(1 556. 22 ±474. 00)VS. (1 633. 89 ±402.03)ug·h·L^-1 and AUC0-∞ (1 607. 13 ± 489.33 ) vs. ( 1 690.79 ±436.43 )ug·h· L^-1. Except T the P values of other parameters showed no statistical difference (P 〉 0. 05 ). Conclusion : Ambroxol dispersable tablets featured a faster onset of actions than ambroxol tablets.
