A simple, rapid and selective HPLC method has been developed for quantization of Amlodipine Besylate and Metoprolol succinate from bulk drug and pharmaceutical formulations using a mobile phase consisting mixture of 0.02 M phosphate buffer solution and Acetonitrile as 80:20 at the flow rate of 1 mL/min. An Inertsil ODS-CV column was used as stationary phase. The retention time of Amlodipine Besylate and Metoprolol succinate were 3.92 and 10.43 respectively. Linearity was observed in the concentration range of 2.5 to 15 µg/ml for Amlodipine Besylate and 25 to 150 µg/ml for Metoprolol succinate, with good linearity response greater than 0.999. Percent recoveries obtained for Amlodipine Besylate and Metoprolol succinate were 100.03 and 100.48% respectively. The proposed method is precise, accurate, selective and rapid for the simultaneous determination of Levofloxacin hemihydrate and Orinadozole.
