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 Linagliptin in pharmaceutical dosage form. The UV spectrum of Linagliptin in ethanol showed λ max at 290 nm. Beer’s law obeyed in the concentration of 10-50mcg/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 recovery was found to be higher than 98% in all experimental conditions. Based upon the performance characteristics, the proposed method was found accurate, precise and rapid and suitable for the determination of Linagliptin for routine analysis.
