Abstract

The work discusses method development and validation. An uncomplicated, accurate, and straightforward method was developed for the drug Esomeprazole in bulk as well as Pharmaceutical dosage form. NaOH was used as the solvent. The maximum wavelength (ʎ max) for Esomeprazole was found to be 305nm. The validation was performed as per International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines for Accuracy linearity, precision, Limit of Detection (LOD) and Limit of Quantification (LOQ). Esomeprazole's recovery percentage (%) was 100.20%, respectively. Linearity for Esomeprazole was observed between 5-25µg/ml, respectively. Regression equation y=0.0407x-0.0122, regression coefficient (r²) is 0.9963 for Esomeprazole. Inter day and intraday precision were checked, % relative standard deviation values were less than 2. The regression equations were used to derive the Limit of Detection (LOD) and Limit of Quantification (LOQ) values. LOD value was found to be 0.734 µg/mL and LOQ value was 2.224 µg/mL for Esomeprazole. The assay of the marketed formulation was performed, which was between 98-102%.  So the method developed was simple and economical that can be adopted for routine tests.
