Abstract:


Background: An enantiomeric separation of the stability-indicating high-performance liquid chromatographic method was developed and validated for the analysis of Meclizine enantiomers. The degradation behavior of Meclizine Hydrochloride was investigated under different stress conditions recommended by the International Conference on Harmonization (ICH).

Experiment: Enantiomeric resolution of the drug and complete separation from its degradation products were successfully achieved on a Phenomenex® lux cellulose 1 C18 (250 mm × 4.6 mm i.d, 5 μm particle size) column, using UV detector at a wavelength of 230 nm, with a 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.

Result: The degradation products were well resolved from the main peak, proving the stabilityindicating power of the method. The developed method provided linear responses within the concentration range of 1-5 μg/mL, and regression analysis showed a correlation coefficient value (r2) of 0.999. The HPLC method was validated as per ICH guidelines with respect to specificity, precision, linearity and robustness. Limit of Detection (LOD) and Limit of Quantification (LOQ) were found to be 0.25 μg/mL and 1.00 μg/mL, respectively.

Conclusion: The method provides good sensitivity and excellent precision and reproducibility. The method was highly selective, in which degradation products and co-formulated compounds did not interfere. The proposed method was successfully applied in pharmaceutical preparations.
