A simple, versatile, accurate, precise and economic method for simultaneous determination of sitagliptin phosphate and simvastatin in fixed dose combination products was developed. The absorbance values at 267 nm and 239 nm for sitagliptin phosphate and simvastatin. The combination is also estimated by AUC method it involved measurement of area under curve in the wavelength range is 264-270 nm (λ1 -λ2 ) and 236-242 nm (λ3 -λ4 ) sitagliptin phosphate and simvastatin respectively. This method obeyed Beer’s law in the concentration range of 10-60 μg /mL for sitagliptin phosphate and 2-12 μg /mL for simvastatin. The results of analyses have been validated statistically for linearity, accuracy, precision, LOD and LOQ of the proposed method.
