Development and Validation of New Analytical Method for The Simultaneous Estimation of Netupitant And Palonosetron In Pharmaceutical Dosage Form

Abstract

A simple, Accurate, precise method was developed for the simultaneous estimation of the Netupitant and Palonosetron in Pharmaceutical dosage form. The chromatogram was run through Std Discovery C18250 x 4.6 mm, 5m. Mobile phase containing Buffer 0.1% OPA (2.2ph): Acetonitrile taken in the ratio 55:45 was pumped through the column at a flow rate of 1 ml/min. The buffer used in this method was 0.1% OPA. The temperature was maintained at 30°C. The optimized wavelength selected was 220 nm. The retention time of Netupitant and Palonosetron was found to be 2.308min and 3.093min. %RSD of the Netupitant and Palonosetron were and found to be 0.9 and 0.6 respectively. %Recovery was obtained as 99.51% and 99.29% for Netupitant and Palonosetron respectively. LOD, LOQ values obtained from regression equations of Netupitant and Palonosetron were 1.84, 0.01, and 5.59, 0.03 respectively. Regression equation of Netupitant  is y = 7232.8x + 3439.3., and y = 28857x + 97.732 of Palonosetron. Retention times were decreased and run time was decreased, so the method developed was simple and economical that can be adopted in regular Quality control tests in Industries.
