Abstract
Objective: The day by day new combinations drugs are being introduced in market. Then the multiple therapeutic agents which acts at different sites are used in the management of various diseases and disorders are done. Thus it is necessary to develop methods for analysis with the help of number of analytical techniques which are available for the estimation of the drugs in combinations. An accurate, precise and reproducible RP-HPLC method was developed for the simultaneous quantitative determination of Metformin Hydrochloride (MET) and Alogliptin (ALO) in tablet dosage forms. Methods: Younglin (S. K.) gradient system UV detector and C18 column with 250 mm x 4.6 mm i. d. and 5μm particle size Acetonitrile: OPA water (80: 20v/v) pH 2.5 was used as the mobile phase for the method. The detection wavelength was 283 nm and flow rate was 0.9ml/min. Results: In the developed method, the retention time of MET and ALO were found to be 6.366 min and 8.616 min. The developed method was validated according to the ICH guidelines. Conclusion: In this methods linearity, precision, range, robustness were observed. The method was found to be simple, accurate, precise, economic and reproducible. So the proposed methods can be used for the routine quality control analysis of MET and ALO in bulk drug as well as in formulations.
