  Rosuvastatin and Ezetimibe are used for the treatment of hyperlipidemia. A stability-indicating RP-HPLC method was developed and validated for the simultaneous determination of Rosuvastatin and Ezetimibe in tablet dosage forms using C 18 column with mobile phase consisting of tetra butyl ammonium hydrogen sulphate-acetonitrile (32:68, v/v) with a flow rate of 1.0 ml/min (UV detection 254 nm). Linearity was observed over the concentration range 0.1-200 μg/ml for both Rosuvastatin (r2=0.9998) and Ezetimibe (r2=0.9998). The LOD and LOQ were found to be 0.0282 μg/ml and 0.0853 μg/m for Rosuvastatin and the LOD and LOQ for Ezetimibe were 0.0297 μg/ml and 0.0901 μg/ml respectively. Rosuvastatin and Ezetimibe were subjected to stress conditions of degradation in aqueous solutions including acidic, alkaline, oxidation, photolysis and thermal degradation. Ezetimibe is highly sen..
