A simple, Accurate, precise method was developed for the simultaneous estimation of the Ritonavir, Ombitasvir and Paritaprevir in tablet dosage form. Chromatogram was run through Ascentis c18 150 x 4.6 mm, 5. Mobile phase containing Acetonitrile and Water in the proportion of 60:40 was pumped through column at a flow rate of 0.8ml/min. Temperature was maintained at 30°C. Optimized wavelength for Ritonavir, Ombitasvir and Paritaprevir was 265nm. Retention time of Ritonavir, Ombitasvir and Paritaprevir Were found to be 2.147 min; 2.732 min and 3.790 min. %RSD of system precision for Ritonavir, Ombitasvir and Paritaprevir were and found to be 0.4, 1.0 and 1.0 respectively. %RSD of method precision for Ritonavir, Ombitasvir and Paritaprevir were and found to be 0.5, 0.4 and 0.8 respectively. % recovery was obtained as 100.30%, 100.19% and 100.15% for Ritonavir, Ombitasvir and Paritaprevir respectively. LOD, LOQ values are obtained from regression equations of Ritonavir, Ombitasvir and Paritaprevir were 0.14ppm, 0.44ppm, 0.06ppm, 0.19ppm and 0.42ppm, 1.28ppm respectively. Regression equation of Ritonavir was y = 28427x + 10360, Ombitasvir was y = 8648.x + 422.2 and of Paritaprevir was y = 39168x + 17464. Retention times are not as much as different techniques so the method developed were basic and conservative that can be received in standard Quality control test in Industries. Retention times are decreased so the method developed basic and conservative embraced in general Quality control test in Industries.

Keywords: Ritonavir. Ombitasvir and Paritaprevir, RP-HPLC.
