Abstract
A simple, Accurate, precise method was developed for the estimation of the Lorlatinib in API form and Marketed pharmaceutical dosage form by RP-HPLC. Chromatogram was run through Hypersil C18 (4.6mm×150mm, 5µm) Particle size Column and Mobile phase containing Methanol and Water taken in the ratio of 25: 75% v/v was pumped through column at a flow rate of 1.0 ml/min. Temperature was maintained at 38ºC. Optimized wavelength selected was 310 nm. Retention times of Lorlatinib were found to be 3.513 minutes respectively. The %RSD for the Repeatability and Intermediate Precision of the Lorlatinib were found to be within limits. %Recovery was obtained 98.96% and it was found to be within the limits for Lorlatinib respectively. The LOD, LOQ values obtained from regression equations of Lorlatinib were 0.332µg/ml and 1.0078 µg/ml respectively. Regression equation of Lorlatinib was found to be y = 39948x + 16821 respectively. The Retention times was decreased and run time was decreased, so the method developed was simple and economical that can be adopted in regular Quality control test in Industries.
