A Photo Stability Indicating HPLC technique for Validation of Netupitant and Palonosetron in Bulk and Formulations

Analytical chemistry is the science that seeks ever improved means of measuring the chemical composition of natural and artificial materials.Netupitant Delayed emesis has been largely associated with the activation of tachykinin family neurokinin 1 receptors. Palonosetron is a selective serotonin 5-HT3 receptor antagonist. The antiemetic activity of the drug is brought about through the inhibition of 5-HT3 receptors present both centrally  and peripherally in turn inhibits the visceral afferent stimulation of the vomiting center.The mobile phase used was orthophosphoric and acetate 70% buffer pH 3 and 30% methanol.The assay of Netupitant and Palanosetron was performed with tablets and the % assay was found to be 100.08 and 100.04, The linearity was found to be linear with a correlation coefficient of 0.999, the precision 0.8 and 0.3 for Netupitant and Palanosetron which shows that the method is precise.The validation of developed method shows that the accuracy is well within the limit, which shows that the method is capable of showing good accuracy and reproducibility. The LOD and LOQ for Netupitant were found to be 3.02 and 9.98 and LOD and LOQ for Palanosetron was found to be 3.00 and 10.00. Thus, it shows that the method is stability indicating, sensitive, accurate, robust and precise. Hence, the developed HPLC method can be successfully applied to the pharmaceutical dosage form and can be used for routine analysis.
