| Abstract | An enantiomeric separation of stability-indicating high performance liquid chromatographic method was developed and validated for the analysis of orphenadrine enantiomers. The degradation behaviour of orphenadrine was investigated under different stress conditions recommended by International Conference on Harmonization (ICH). Enantiomeric resolution of the drug and complete separation from its degradation products were successfully achieved on a Phenomenexฎ lux cellulose 1 C18 (250 mm ื 4.6 mm i.d, 5 ?m particle size) column, using UV detector at a wavelength of 241 nm, with mobile phase consisting of acetonitrile, 20mM ammonium bicarbonate at the ratio of 75:25 (v/v), and a flow rate of 1 mL/min. The drug was subjected to alkaline, acidic, neutral, oxidative and photolytic conditions in order to mimic stress conditions. The degradation products were well resolved from main peak and, proving the stability-indicating power of the method. |
