Mifepristone structurally belongs to the class of anti-progesterone steroids, which are used as an oral contraceptive. The reverse phase HPLC method was designed in a simplified and rapid way for the estimation of Mifepristone in bulk as well as tablets. The method was established using a Kromasil C18 column of dimensions of 250mm×4.6mm and a particle size of 5m.The used mobile phase was Acetonitrile: Water (70:30, v/v). The pump was pumped at 1 ml/min at a temperature of about 30 ± 2 °C and the eluted analyte was identified at 305 nm. Mifepristone eluted with a mean retention time of 6.27 minutes. The intended method was validated as per ICH (International Council for Harmonisation) guidelines, indicating a high degree of specificity, system suitability, accuracy, precision, and robustness. The LOD (Limit of detection) was found to be 0.7238 ppm and the limit of measurement was 0.9562 ppm. The method linearity was found to be between 1-6µg/ml, with an R2 of 0.9923. In accuracy studies, the percent recovery was found to be between 99.39% - 100.50%. The method was discovered to be precise as the values of the percent RSD were found to be less than 2.0% for both intraday and interday. The method was discovered to be reliable and robust. Mifepristone in marketed pharmaceutical tablet dosage form was effectively quantified using the established Reverse Phase HPLC method.
