A simple, rapid, accurate, precise, specific and sensitive reverse phase-HPLC method has been developed and validated for the simultaneous estimation of Sofosbuvir and Velpatasvir in bulk and pharmaceutical dosage form. The chromatographic separation was performed on the Discovery C18 column (250mm×4.6mm, 5?m particle size), using a mobile phase of OPA (0.1%): Acetonitrile = 50:50 (v/v), at a flow rate of 1.0 ml/min in an ambient temperature of 25?C with the detection wavelength of 260nm. The retention times of Sofosbuvir and Velpatasvir were 2.47 min and 3.32 min respectively. The linearity was performed in the concentration range of 100-600 µg/mL, 25-150?µg/mL each of Sofosbuvir and Velpatasvir with a correlation coefficient of 0.998 and 0.999 for Sofosbuvir and Velpatasvir respectively. The proposed method has been validated for specificity, linearity, range, accuracy, precision and robustness were within the acceptance limit according to ICH guidelines and the developed method can be employed for routine quality control analysis in the bulk and combined pharmaceutical dosage form.
