High performance liquid chromatography is at present one of the most sophisticated tool of the analysis. The estimation of Glecaprevir and Pibrentasvir was done by RP-HPLC. The Phosphate buffer was pH 4.5 and the mobile phase was optimized with consists of Methanol: Phosphate buffer mixed in the ratio of PH 4.5(20:80 v/v). Kromosil C18 Column (250mm x 4.6mm) 5µg or equivalent chemically bonded to porous silica particles was used as stationary phase. The detection was carried out using UV detector at 254 nm. The solutions were chromatographed at a constant flow rate of 1 ml min-1. The linearity range of Glecaprevir and Pibrentasvir were found to be from 100-500 mg/ml of Glecaprevir and 1-5mg/ml of Pibrentasvir. Linear regression coefficient was not more than 0.999. The values of % RSD are less than 2% indicating accuracy and precision of the method. Glecaprevir %RSD 0.2 and Pibrentasvir %RSD 0.6. Intermediate precision for Glecaprevir %RSD 0.2 and Pibrentasvir %RSD 0.1 LOD and LOQ were found to be within limit. The results obtained on the validation parameters met ICH and USP requirements.
