Zusammenfassung:Experimental design is a significant tool for optimization and validation for the development of HPLC methods to determine API in both human serum and pharmaceutical formulations. In this study, RP-HPLC method is developed and validated for the simultaneous determination of moxifloxacin and NSAIDs. In this experiment, Purospher STAR C18 column with optimum assay conditions (10:90, v/v, water: methanol, pH 2.75) used as mobile phase having flow rate of 1.5mL min and screened at 240 nm. The experimental results exhibit reliability through accuracy (98-102%), precision (0.011-1.85%) and linearity (R >0.999) in range of 0.15-40μgmL . The LOD and LOQ limits for moxifloxacin and NSAIDs are found to be 0.015 and 0.046 μgmL respectively. The significant outcomes conclude that the developed method for assay is effectively suitable to human serum and pharmaceutical formulations and there is no interference from excipients of tablets and serum. The proposed method is useful for drug-interaction and investigation of moxifloxacin with NSAIDs.
