摘要: 目的: 研究瑞格列奈的药代动力学和药效动力学。方法: 19 名健康男性受试者单剂量口服4 mg 瑞格列奈片, 采用HPLC-MS-MS 法测定给药后不同时间瑞格列奈的血药浓度, 用快速血糖仪测定不同时间指尖血的血糖。利用DAS 2.0 计算药动学参数和进行统计分析。结果: 瑞格列奈体内过程符合一室开放模型, 达峰浓度Cmax 为(83.1±23.6)μg/L;达峰时间tmax 为(0.71±0.21)h ;AUC0-8 为(97.1±37.8)μg·L-1·h ;t1/2 为(1.6±0.7)h 。给药后血药浓度水平升高, 血糖随之下降, 于给药后1 h 最低, 达(3.0±0.65)mmol/L。结论: 瑞格列奈起效迅速、作用持续时间短, 适合餐后血糖调节, 用于通过运动和控制饮食治疗无效的2 型糖尿病患者。

Abstract: AIM: To study the pharmacokinetics and pharmacodynamics of repaginide in healthy volunteers. METHODS: 19 healthy male volunteers in single oral dose of repaglinide tablets 4 mg. The plasma concentrations of repaglinide were determined by HPLC-MS-MS. The glucose levels of fingertip blood were measured by blood glucose monitoring system. The pharmacokinetic parameters were obtained by statistical analysis of DAS Ver 2.0.RESULTS: Plasma concentration-time curve conformed to one-compartment open model. The main pharmacokinetic parameters: Cmax, tmax, AUC0-88 and t1/2 were (83.1±23.6) μg/L, (0.71±0.21)h, (97.1±37.8)μg·L-1·h, (1.6±0.7)h. The level of blood concentration was increased and blood glucose was decreased and reached its lowest value (3.0±0.65)mmol/L 1 h after administration of repaglinide. CONCLUSION: Repaglinide is characterised by fast-acting and short effects on insulin secretion. It is a prandial glucose regulator for treatment of type 2 diabetes mellitus that is not controlled by exercise and diet.

Key words: repaglinide, pharmacokinetics, pharmacodynamics, blood glucose
