Abstract
A simple, sensitive, rapid, accurate, precise and economical Q-absorbance ratio method has been developed for the simultaneous estimation of eperisone hydrochloride and aceclofenac in combined dosage form. The solvent used was methanol:water (70:30 v/v). The iso-absorptive point was found to be 269.5 nm. Calibration curves were linear over a concentration range of 6-21 μg/ml for eperisone hydrochloride and 8-28 μg/mL for aceclofenac, respectively. The developed method was validated as per International Conference on Harmonization (ICH) guidelines for various parameters such as linearity, precision, accuracy, limit of detection and limit of quantitation. Accuracy of method was determined through recovery studies which were found to be 99.0% - 100.89 % for eperisone hydrochloride and 98.67% - 100.44 % for aceclofenac. Method was found to be reproducible with relative standard deviation (RSD) for intra-and inter-day precision less than 2% over the concentration range. The proposed method can be used for routine analysis of eperisone hydrochloride and aceclofenac in bulk and tablet dosage form.
