The aimed of research the method development and validation by UV spectrophotometry and RP HPLC method of the Rosuvastatin calcium and Clopidogrel bisulphate. The method is a simple, accurate, specific, precise, reproducible and sensitive. The λ max of ROSU and CLOP was found to be 240nm. The coefficient correlation 0.999, the Beer's Law limit 50–150 μg/ml, from the four trial of different concentration of mobile phase was selected Methanol: Water 80: 20 v/v, pH 3.0 at 240nm, flow rate 1ml/min, sample inlet 20 μL, C 18 Prontosil, %RSD of ROSU 1.017 and CLOP 0.173, theoretical plates ROSU 7797.53 and ROSU 8257.53, Retention time of ROSU 3.483min and CLOP 4.983min, Tailing factor ROSU 1.1787 and CLOP 1.074, limits 2 NMT, Accuracy ROSU 0.37% RSD, Recovery 99.59% and CLOP 0.18%RSD, recovery 100.41% was show good efficacy and results. The methods indicate future scope in analysis quality control of the estimation of ROSU and CLOP for routine drug quality analysis investigation.
