Description
Summary:Objective: The present paper describes a simple, accurate, and precise reversed-phase high-performance liquid chromatography (HPLC) method for rapid and simultaneous quantification of dolutegravir (DTG) and rilpivirine (RPV) in bulk and pharmaceutical dosage form and rat plasma. Methods: The chromatographic separation was achieved on Phenomenex C18 (150x4.6mm, 5μm). Mobile phase contained a mixture of 0.1% Ortho phosphoric acid and acetonitrile in the rato of 60:40 v/v, flow rate 1.0ml/min and ultraviolet detection at 262nm. Results: The retention time of DTG and RPV was 4.35 min and 7.73 min, respectively. The proposed method shows a good linearity in the concentration range of 10–150 μg/ml for DTG and 5–75 μg/ml for RPV under optimized conditions. Precision and recovery study results are in between 98 and 102%. In the entire robustness conditions, percentage relative standard deviation is
