摘要: 介绍了高效液相色谱电化学检测法测定了血中间羟舒喘宁(博利康尼)浓度, 采用固相提取和双电极技术, 并用瑞典Astra公司生产的间羟舒喘宁缓释片作为参照标准, 研究了华瑞制药有限公司(SSPC)生产的间羟舒喘宁缓释片的药代动力学和生物利用度, 比较了两种缓释片的最大血浓度(Cmax)、达峰时间(tmax)和曲线下的面积(AUC0→∞)。结果表明, SSPC的间羟舒喘宁缓释片与Astra公司生产的间羟舒喘宁缓释片, 生物利用度相似。

Abstract: A sensitive and selective high-performance liquid chromatographic- electrochemical method using olid-phase column extraction and dual series electrode was described for the study ofpharmacokinetics and bioavailabilitv of terbutaline slow-release (SR) tablet made by SSPC (China, Bricanyl II). The erbutaline SR tablet made by Astra (Bricanyl I) was used as reference formulation The comparison of three pharmacokinetic parameters between the two SR tablets showed that the maximal serum concentration (Cmax), the time reaching Cmax (tmax) and the area under serum concentration-time profiles (AUC0→∞)were of no practical difference (P>0.05). The mean relative bioavailability of Bricanyl II compared with Bricanyl I was 105 % in 5 mg.

Key words: High-performance liquid chromatography-electrochemical detection, Solid-phase extraction, Terbutaline, Slow release tablets, Pharmacokinetics, Bioavailabiliy
