Abstract

Two simple precise and accurate U.V Spectrophotometric methods were developed and validated according to ICH guidelines. Method A: methanol was used as a solvent and absorption maximum was found at 297nm.method B: methanol: acetonitrile (50:50) was used as a solvent and absorption maximum was found at 295nm.Validation parameters such as accuracy, linearity, robustness were performed. % assay and %RSD was calculated and results were found within the predetermined limits. This indicated that the proposed methods can be used in routine analysis of Nimesulide in bulk and pharmaceutical formulations.
