A simple, accurate, RP HPLC method was developed by this study determination of lenalidomide. This method is developed by Shimadzu LC-2010 HT by using C18 (250 X 4.6 X mm X 5μ) column in solvents Phosphate buffer: Acetonitrile (55: 45) v/v as mobile phase and the temperature was maintained at 25°C. The mobile phase flow rate 1ml/min was pumped and sample wavelength was detected at 242nm by ultraviolet-visible spectrophotometer. The retention time was found 2.5 min. The number of theoretical plates and tailing factor for lenalidomide was observed 16199.817 (NLT 2000) and 1.128 (NMT 2). The method was validated for analytical standards such as linearity, accuracy, precision, system suitability and robustness. LOD and LOQ values obtained from regression of lenalidomide 0.058 and 0.174μg/ml. The regression equation of validated method for lenalidomide is Y=5223x+183075. In wide range of 25 to 150 (μg/ml) the linearity was observed. The method was validated and a recovery study indicates accuracy of this method. The Retention time less compared to established methods. The method was validated by determining its accuracy, precision and system suitability. The results of the study showed that the proposed RP-HPLC method is simple, rapid, precise and accurate, which is useful for the routine determination of Lenalidomide in bulk drug and in its pharmaceutical dosage forms.
