A very simple, more accurate, and highly precise process is refined to development of two combination drugs Dolutegravir (DUA), Rilpivirine (RPV)in the tablet dosage form. For this development Agilent 100-5C18 column (250mm x 4.6mm).Acetonitrile as 40v/v and Phosphate buffer which is maintained at pH 4.0as 60v/vis passed with the help of column. Flow rate was measure as 0.80ml/min. Column temperature is accompanied as ambient. Upgraded wavelength is 235 nm. Run time is identified as 10 minutes and the volume injected for this analysis is 20 µl. Retention time of DUA and RPV were found to be 2.6 & 3.9min. %RSD of the DUA and RPV were and found to be 0.87, 0.40 as intraday and 0.75 and 0.56 as inter day precision. % Recovery was obtained as 98.59%, 100.7% for DUA and RPV respectively. The Rt values are minimized as well as run time was decreased. Finally, concluded that this proposed and developed process is more simple as well as economical which should be prevalent in regular QC labs and present in the plasma samples.
