摘要目的:建立复方呋塞米螺内酯胶囊(FuSpirC)的质量控制方法。方法:用高效液相色谱法测定复方制剂中呋塞米和螺内酯的含量。结果:色谱柱:Kromasil C(18)柱(200 mm×4.6 mm,5 μm),流动相为甲醇∶0.02 mol/L磷酸二氢钾(67∶33)(0.85%磷酸调节pH 至4.3),流速0.8 mL/min,检测波长为239 nm,呋塞米、螺内酯分别在5~35 μg/mL、20~80 μg/mL浓度范围线性关系良好,呋塞米平均回收率分别为98.29%(RSD=0.08%,n=3)、99.20%(RSD=0.48%,n=3)、99.18%(RSD = 0.36%,n=3),螺内酯平均回收率分别为101.76%(RSD=0.13%,n=3)、101.35%(RSD=0.52%,n=3)、101.67%(RSD = 0.27%,n=3),平均回收率的RSD均小于2%,符合方法学要求,呋塞米、螺内酯平均含量分别为94.79%、99.76%,均符合要求。结论:所建立方法可用于复方呋塞米螺内酯胶囊的质量控制。

Abstract Objective:To develop a method for controlling the quality of compound FuSpirC.Methods:High performance liquid chromatography was used to determine the contents of furosemide and spironolactone in compound FuSpirC.Results:Column was represented by Kromasil-C18(200 mm×4.6 mm,5 μm),mobile phase was methanol:0.02 mol/L potassium dihydrogen phosphate(67:33)(used 0.85% phosphoric acid adjust pH 4.3),flow rate 0.8 mL/min,detected wavelength was 239 nm,the concentrations of furosemide and spironolactone were 5~35 μg/mL and 20~80 μg/mL,respectively,and were in good linear relationship.The average recovery rate of furosemide were 98.29%(RSD = 0.08%,n=3),99.20%(RSD = 0.48%,n=3),99.18%(RSD = 0.36%,n=3),while spironolactone were 101.76%(RSD = 0.13%,n=3),101.35%(RSD = 0.52%,n=3),101.67%(RSD = 0.27%,n=3),the average recovery of RSD was less than 2%,conformed to the requirement of the methodology.The content of furosemide and spironolactone were 94.79% and 99.76%,conformed to the requirements.Conclusion:The methods can be used for quality control of compound FuSpirC.

呋塞米为强效利尿剂,其作用机制主要是抑制肾小管髓袢升支粗段髓质部Na+、C1-的主动再吸收,因而尿中Na+、K+与水的排出增加而产生利尿作用[1]。此外,还有扩张肾小动脉的作用。长期或大剂量应用,可引起低钾血症、低钠血症和代谢性酸中毒。严重时因血容量降低,导致休克甚至死亡[2]。螺内酯为人工合成的类固醇类药物,其结构与醛固酮类似,两者在肾远曲小管和集合管的皮质段起竞争作用,干扰醛固酮保钠排钾的作用,对伴有醛固酮增高的顽固水肿有治疗作用,且可防止钾的耗竭,在临床上有重要用途[3],对心力衰竭也有一定的疗效[4]。……
