An aqueous alkaline degradation study was performed for imidapril hydrochloride (IMD) drug in the presence of its degradation products and an isocratic stability indicating method was presented using a HPLC technique. The separations were performed using an ACE Generix 5C8, 150 × 4.6 mm column and a mobile phase consisting of buffer solution (0.1 M potassium dihydrogen phosphate and 0.02 M tetra-N-butyl
在其降解产物存在下,对盐酸咪达普利(IMD)药物进行了碱性水溶液降解研究,并提出了使用HPLC技术的等度稳定性指示方法。使用ACE的Generix 5C8,150×4.6mm柱和由缓冲溶液的流动相进行分色(0.1M磷酸二氢钾和0.02M的四Ñ pH为丁基氢硫酸铵= 4.5用1N HCl)和乙腈60:40(v / v)。将检测器的波长调节为210nm。该方法表明有关从0.1至100μg毫升在可接受的范围内准确度,精密度,线性度和特异性高灵敏度-1和定量限被发现是0.0211微克毫升-1用于IMD。所提出的方法用于确定其药物制剂中的药物,并研究该药物在碱性条件下样品的降解动力学。发现反应遵循一级反应。还可以估计活化能。根据ICH指南验证了优化的稳定性指示HPLC方法。
