摘要 目的建立高效液相色谱-荧光法(HPLC-FLD)测定马来酸氟吡汀的血药浓度,并使用该方法评价2种马来酸氟吡汀胶囊在健康人体的生物等效性。方法采用随机、开放、两周期交叉、单次口服给药的单中心试验设计。24例健康男性受试者单次口服试验制剂或参比制剂的马来酸氟吡汀0.1 g,测定其血药浓度,计算药物动力学参数并进行生物等效性评价。结果在0.023 4~1.50 mg·L-1马来酸氟吡汀浓度与峰面积线性关系良好。试验制剂与参比制剂血浆中马来酸氟吡汀的tmax为(2.0±0.8)和(2.0±1.2)h;Cmax为(1.11±0.28)和(1.25±0.29)mg·L-1;t1/2为(8.6±2.3)和(8.0±1.1)h;AUC0~t为(9.18±2.14)和(9.11±2.31)mg·h·L-1;AUC0~∞为(9.70±2.20)和(9.62±2.29)mg·h·L-1。分别以AUC0~t和AUC0~∞计算,相对生物利用度为(99.54±11.11)%和(99.52±9.63)%。结论 HPLC-FLD法可用于测定血浆中的马来酸氟吡汀浓度;马来酸氟吡汀的两制剂具有生物等效性。 Objective To establish an HPLC-FLD method to determine flupirtine maleate in human plasma and its bioequivalence in healthy Chinese volunteers.Methods A single oral dose of 0.1 g reference and test preparation was given to 24 healthy volunteers in an open randomized 2-way crossover design.The plasma concentrations were determined by HPLC-FLD method.Results The flupirtine maleate curve was linear at 0.023 4-1.50 mg·mL-1.The main pharmacokinetic parameters of the test and reference preparations were as follows: tmax was(2.0±0.8) and(2.0±1.2) h;Cmax was(1.11±0.28) and(1.25±0.29) mg·L-1;t1/2 was(8.6±2.3) and(8.0±1.1) h;AUC0~t was(9.18±2.14) and(9.11±2.31) mg·h·L-1;AUC0~∞was(9.70±2.20) and(9.62±2.29) mg·h·L-1.Calculated by AUC0~t and AUC0~∞ respectively,the average relative bioavailability for the test flupirtine maleate was(99.54±11.11) % and(99.52±9.63) %.Conclusion The HPLC-FLD method is feasible for determining flupirtine maleate in human plasma and the test and reference preparations are bioequivalent.
