Development and Validation of UV Spectroscopy Method for the Estimation of Dolutegravir in Bulk and Pharmaceutical Dosage Form

UV spectroscopic method was developed for the estimation of Dolutegravir in bulk and Formulation.The UV spectrum of Dolutegravir in methanol and water mixture showed λ max at 254nm. Beer's law is valid in the concentration range of 10–50μg/ml. This method was validated for linearity, accuracy, precision, LOD and LOQ. The method has demonstrated excellent linearity over the range of 10–50μg/ml with regression equation y = 0.030x + 0.008 and regression correlation coefficient r²= 0.998. Moreover, the method was found to be highly sensitive with LOD (2.056μg/ml) and LOQ (6.230μg/ml). Depending on results the given method can be successfully applied for assay of Dolutegravir in formulation.
