  [摘要] 目的 建立恩替卡韦反相高效液相色谱(RP-HPLC)分析方法,测定口腔速溶膜剂中药物含量。 方法 以聚乙烯醇/聚乙二醇接枝共聚物为成膜材料,溶剂浇注法制备恩替卡韦口腔速溶膜剂。采用Inertsil ODS-3 C18 (4.6 mm×150 mm,5 μm)色谱柱,以乙腈-水(3∶97)和乙腈为流动相A和流动相B,检测波长254 nm,流速1.0 mL/min,柱温25℃,进样量20 μL,利用梯度洗脱程序测定恩替卡韦口腔速溶膜剂中药物含量。 结果 恩替卡韦标准溶液线性回归方程为:A=52548.1316C-639.5153 (R2=0.9999),日内精密度为0.15%~0.56%,日间精密度为0.35%~1.36%,准确度为99.70%,定量限为0.31 ng,检测限为0.26 ng,且药物溶液在24 h内稳定。恩替卡韦口腔速溶膜剂中药物含量为(98.93±0.55)%。 结论 本研究RP-HPLC分析方法专属性强,精密度、准确度高,稳定性好,适用于恩替卡韦口腔速溶膜剂中药物含量测定。

  [Abstract] Objective To establish a reverse phase high performance liquid chromatography (RP-HPLC) method for the determination of drug content in entecavir-loaded orodispersible films (ODFs). Methods The entecavir-loaded ODFs were prepared by using a solvent casting method with polyvinyl alcohol/polyethylene glycol graft copolymer as a film-forming agent. The RP-HPLC analysis was performed on an Inertsil ODS-3 C18 (4.6 mm×150 mm, 5 μm) column with mobile phases composed of acetonitrile-water (3∶97) and acetonitrile. The flow rate of mobile phase was 1.0 mL/min. The wavelength of UV detector was set at 254 nm and the injection volume was 20 μL. The column temparature was mantained at 25℃. The drug content of entecavir-loaded ODFs was analyzed by a gradient elution mode. Results The linear regression equation of entecavir standard solution was A=52548.1316C-639.5153 (R2=0.9999). The intra-day precision was 0.15%-0.56%, the inter-day precision was 0.35%-1.36%, and the accuracy was 99.70%. The limit of detection was 0.31 ng and the limit of quantitation was 0.28 ng. The drug solution was stable within 24 h. The drug content of entecavir-loaded ODFs was (98.93±0.55)%. Conclusion The RP-HPLC method of entecavir shows high specificity, good precision, accuracy, and stability. This method is suitable for the detemination of drug content in entecavir-loaded ODFs.

  恩替卡韋为环戊基鸟嘌呤核苷类似物,是选择性抗HBV的口服核苷类药物[1-2]。恩替卡韦片剂(商品名:博路定)是由Bristol–Myers Squibb公司研发并于2005 年3月29日美国食品药品监督管理局(FDA)批准上市[3],2005年11月15日经中国国家食品药品监督管理局批准在中国上市[4]。目前,临床上应用的恩替卡韦治疗慢性乙型肝炎(CHB)的剂型,主要有普通片剂、分散片以及胶囊剂。已有报道的新剂型包括软胶囊剂[5]、液体制剂[6]、滴丸[7]、肠溶剂[8]及固体分散体[9]等。口腔速溶膜剂是将一定剂量的有效成分溶于或分散在成膜材料中制成的制剂[10],可在一分钟内于唾液中崩解,释放出有效成分,经口腔黏膜吸收,同时使药物经过吞咽后能在胃肠道内快速溶出并吸收[11]。口腔速溶膜剂与口腔崩解片、分散片等其它常规剂型相比,具有很多优势,如体积小,重量轻,便于携带运输和贮存,工艺简单,无水条件可服药等[12-13]。经多方文献调查研究,目前国内外文献中对恩替卡韦口腔速溶膜剂的研究,尚未见相关文献报道。本研究以聚乙烯醇/聚乙二醇接枝共聚物(Kollicoat?誖 IR)为成膜材料[14-15],溶剂浇注法[16]制备新型恩替卡韦口腔速溶膜剂,并采用反相高效液相色谱对其进行分析方法建立和含量测定[17-18]。
