A simple, selective, rapid, precise and economical reverse phase HPLC method has been developed for the determination of Metoprolol Succinate in dosage formulation. The analyte was resolved by using a mobile phase (Acetonitrile, water and 1 % ortho phosphoric acid in the ratio 70:27:3 v/v/v) at a flow rate 2.0 ml/min on an isocratic HPLC system (Agilent 1100 series with Chemstation software) consisting UV lamp detector, Aligent C-8, RP column (4.6 mm i.d x250 mm) at a wavelength of 280 nm.  The linear dynamic range for Metoprolol Succinate was 10 g/mL–200µg/mL. The limit of detection [LOD]and Limit of quantification[LOQ] for Metoprolol Succinate  was 0.0284µg/mL  and 0.094µg/mL respectively.
