ABSTRACT
Analytical method development and validation is important in development of Pharmaceutical preparations. The aim of the present work was to develop and validate a simple UV spectroscopic method for the determination of dapagliflozin in pharmaceutical dosage form. The UV spectrum of dapagliflozin in methanol showed λ max at 225nm. Beer's law obeyed in the concentration range of 5- 25µg / ml. This method was carried out according to ICH Q2R1 guidelines by taking the parameters for linearity, accuracy, precision, ruggedness and robustness. The method was rugged and robustness with % relative standard deviation less than 2. The extraction recoveries was found to be higher than 99% in all experimental conditions. Based upon the performance characteristics the proposed method was found accurate, precise and rapid and suitable for the determination of dapagliflozin for routine analysis.
Keywords: Dapagliflozin, UV spectrophotometry, Method development, Validation.
