Statins drugs are thought to be among the most prescribed drugs worldwide for the treatment of hypercholesterolaemia. A simple and reliable RP-HPLC method has been successfully employed for simultaneously separating and qualifying three statin drugs including atorvastatin, rosuvastatin and simvastatin in pharmaceutical tablets. The optimal conditions were mobile phase 50:50 (v/v) (formic acid pH 2.50: ETOH), column temperature 40.00 °C, detection wavelength 238.00 nm, and flow rate 1.00 mL/min. The proposed method has been validated based on the ICH guidelines in terms of linearity, precision, accuracy, and limit of detection and limit of quantification. The linear range investigated 2.0–80.0, 4.0–100.00, and 12.00–120.00 µg/mL for rosuvastatin, atorvastatin and simvastatin respectively with coefficients of determination (R2) within the range of 0.9993–0.9995. The LOD and LOQ for rosuvastatin, atorvastatin and simvastatin were (1.57, 4.76 µg/mL), (1.87, 5.66 µg/mL), (3.46, 10.49 µg/mL) respectively. In addition, in order to evaluate the feasibility of the method developed, it was employed towards the quantification of the pharmaceutical tablets for the analytes investigated and excellent recovery was obtained.
