ABSTRACT
The simple, specific, accurate, precise and reproducible methods have been developed and validated for the simultaneous estimation of both drugs in their combined dosage form. In RP-HPLC, analysis is carried out using Buffer (KH2PO4 50mM 4.5 pH): Methanol (55:45 %v/v) pH 4.5 adjusted by Orthophosphoric acid) mobile phase and BDS hypersil C18, 250mm × 4.6mm, 5µ(particle size), Thermo scientific as stationary phase with detection wavelength of 232 nm. Linearity was obtained in the concentration range of 5-15µg/ml and 50-150µg/ml for Linagliptin and Metformin Hydrochloride respectively. The % recoveries of the both the drugs were found to be 99.81-100.21% and 99.74-100.15%respectively. LOD were found to be0.18 µg/ml and 6.24µg/ml at nm for Linagliptin and Metformin Hydrochloride respectively. Methods were statistically validated for accuracy, precision, specificity, LOQ, robustness and ruggedness according to ICH guidelines and can be used for analysis of combined dosage form.
