Method Development and Validation of Simultaneous Estimation of Cabotegravir and Rilpivirine Using RP-HPLC Method

Abstract

For the simultaneous estimate of Cabotegravir and Rilpivirine in pharmaceutical dose form, a simple, accurate, and exact approach was established. BDS C8 150 x 4.6 mm, 5m chromatogram was done. A mobile phase containing 0.1% orthophosphoric acid:acetonitrile in a 50:50 ratio was pushed down the column at a flow rate of 1.0 ml/min. 0.1% Ortho phosphoric acid buffer was utilized in this procedure. The temperature was kept at 30°C. The optimal wavelength chosen was 257 nm. Cabotegravir and Rilpivirine retention times were determined to be 2.950 min and 3.518.%RSD of Cabotegravir and Rilpivirine were found to be 0.8 and 0.5, respectively. %Cabotegravir and Rilpivirine recovery rates were 99.19% and 98.90%, respectively. LOD and LOQ values derived from regression
