Determining the Content and Release Rate of Dextromethorphan Hydrobromide from Sustained Capsule with UV

  • 摘要: 建立了紫外分光光度法测定氢溴酸右美沙芬缓释胶囊的含量及溶出度方法,测定波长:(278±1)nm,在10~160μg/ml浓度范围内线性相关(r=0.9999),平均回收率99.50%(CV=0.42%),氢溴酸右美沙芬UV法和非水滴定含量测定结果无显著性差异(P>0.01),溶出度(小杯法)测定结果表明:缓释胶囊体外缓释明显,12h内累积释药量>80%,6h内释药曲线符合Higuchi方程[F(t)=25.82+18.90,r=0.9937]。
