Simple, rapid, sensitive, accurate, robust & rugged stability indicating analytical method for determination of Moxifloxacin HCl in pharmaceutical formulations is developed and validated by using UPLC & applied the developed and validated method for determining the assay of Moxifloxacin HCl in tablets (Avelox®), as there is no official monograph & no analytical method by UPLC. Chromatography was performed with mobile phase containing potassium dihydrogen ortho phosphate (adjusted to pH 1.8 with orthophosphoric acid), Methanol & acetonitrile in the ratio of 60:20:20, with a flow rate of 0.3mL/min, C-18 column & UV detection at 296nm.The method was validated for linearity, accuracy, ruggedness, robustness, precision & bench top stability of sample & standard solution. Moxifloxacin tablets were subjected to different stress conditions like acid, alkali, peroxide, thermal, water & UV studies and checked for its specificity, degradation & stability. The developed method was very rapid with a run time of 3 min, accurate, robust, rugged and stable.
