- Abstract
Background: Diclofenac Sodium (DCL) and Moxifloxacin HCl (MOX) were simultaneously used after cataract surgery to reduce the post-operative inflammation and to control infection respectively. Objectives: Three simple, accurate, eco-friendly and reproducible UV spectroscopic methods were established for concurrent determination of diclofenac sodium and moxifloxacin in ophthalmic preparation without prior separation. Methods: The first technique was established on the measurement of a peak amplitude of the first derivative spectra at the zero-crossing wavelength of one analyte. The second method was the determination of peak amplitude difference between peak and trough of ratio spectra. The third method involves the measurement of the peak amplitude of the first derivative of ratio spectra. Water has been used as a solvent. Results: The analytes exhibited good linearity in the range of 1 -15 µg/mL for DCL and 1-18 µg/mL for MOX with excellent correlation coefficient ( r²>0.999). Low percent relative standard deviation confirmed the precision of the methods. Excellent recovery with low percent relative error proved the accuracy of the methods. The specificity of the methods was evaluated by analyzing the laboratory prepared solutions of DCL and MOX. Conclusion: Proposed three techniques were effectively utilized for the simultaneous determination of DCL and MOX from ophthalmic preparation. The outcomes of the proposed procedures were compared with the earlier described methods and no statistical difference was found between the methods in terms of accuracy and precision.
