A simple, accurate and economic UV spectrophotometric method has been developed for the estimation of amlodipine besylate in bulk and tablet formulation. Amlodipine besylate has maximum absorbance at 366 nm in 0.01% O-phosphoric acid. Beer’s law is obeyed in the concentration range of 5-25 mcg/ml with correlation coefficient 0.9997. The developed method was applied for the estimation of amlodipine besylate in bulk and tablet formulation and gave satisfactory results. The proposed method was validated statistically as per ICH guidelines and the low values of %RSD indicate high precision of the method.
