摘 要:目的:评价盐酸特比萘芬片在健康人体的相对生物利用度和生物等效性。方法:20名健康受试者随机交叉单剂量口服盐酸特比萘芬片受试制剂(T)和参比制剂(R),采用液质联用分析方法(LC-MS/MS)测定血浆中特比萘芬浓度。结果:20名健康受试者口服受试制剂和参比制剂后的主要药代动力学参数为:Tmax分别为(1.7±0.6)和(2.2±0.7)h;Cmax分别为(1 590±489)和(1 266.6±432.8)ng·mL-1;t1/2分别为:(21.6±3.6)和(21.0±10.1)h;AUC0~t分别为(8 272.2±2 280.6)和(8 138.9±2 424.0)ng·h·mL-1。受试制剂的AUC0~t或Cmax的90%置信区间对应于参比制剂相应参数的93.44%~111.87%或112.83%~141.91%范围内;受试制剂相对于参比制剂的相对生物利用度为(105.5±26.3)%。结论:受试制剂与参比制剂的生物利用度相当,但受试制剂峰浓度增加,达峰时间提前,没有增加不良反应,疗效也未见降低。Objective:To evaluate the relative bioavailability and bioequivalence of terbinafine hydrochloride tablets in healthy volunteers.Methods:The plasma concentrations of terbinafine in 20 healthy subjects,who received a single crossover dose of test formulation(T) and reference formulation(R),were measured by LC-MS/MS.Results:The pharmacokinetic parameters of the test and reference terbinafine were as follows:Tmax,(1.7±0.6) and(2.2±0.7)h;Cmax,(1590±489) and(1266.6±432.8)ng·mL-1;t1/2,(21.6±3.6) and(21.0±10.1)h;AUC0~t,(8272.2±2280.6) and(8138.9±2424.0)ng·h·mL-1,respectively.The 90% CIs of the AUC0~t and Cmax of the test formulation were respectively within 93.44%~111.87% and 112.83%~141.91% of the reference preparation.The relative bioavailability of the test formulation to the reference formulation was(105.5±26.3)%.Conclusion:The test and reference formulations are basicly bioequivalent.The test formulation has higher Cmax and shorter Tmax compared to the reference formulation without increase in adverse effects.
