摘要

Objective: To develop accurate, fast, simple, and precise reversed-phase high-pressure liquid chromatography method for simultaneous determination of the binary mixture of metformin (MET) and empagliflozin (EMPA) in dosage forms. Methods: The method uses a mobile phase consisting of phosphate buffer, acetonitrile, methanol (15:80:5 v/v/v), an octadecyl silica C-18 column (4.6?mm?×?250?mm,?5?μ?particle?size)?in?isocratic?mode,?detection?wavelength?of?227?nm,?and?a?flow?rate?of?1?mL/minutes. Results: The measured retention times for MET and EMPA and were 2.528 and 4.140?minutes, respectively. The percentage recoveries of MET and EMPA were?101.12%?and?100.55%,?respectively.?The?relative?standard?deviation?for?assay?of?tablets?was?found?to?be?<2%.?The?correlation?coefficient?for?MET?and EMPA?was?found?to?be?0.9990.?The?limit?of?detection?and?quantification?for?MET?was?0.10?μg/mL?and?0.31?μg/mL?and?for?EMPA?0.01?μg/mL?and?0.03?μg/mL. Conclusion:?The?method?was?fast,?accurate,?precise,?and?sensitive?hence?it?can?be?employed?for?routine?quality?control?of?tablets containing both drugs in quality control laboratories and pharmaceutical industries.
