RP-HPLC method development and validation for the simultaneous estimation of fosnetupitant and palonosetron in bulk and combined formulation

Abstract

A rapid and precise reverse phase high performance liquid chromatographic method has been developed for the validated of Palonosetron and Fosnetupitant, in its pure form as well as in tablet dosage form. Chromatography was carried out on a Altima C18 (4.6 x 150mm, 5µm) column using a mixture of Methanol: TEA Buffer pH 4.5: Acetonitrile (50:25:25) as the mobile phase at a flow rate of 1.0ml/min, the detection was carried out at 225 nm. The retention time of the Palonosetron and Fosnetupitant was 2.102, 3.537 ±0.02min respectively. The method produce linear responses in the concentration range of 5-25mg/ml of Palonosetron and 12.5-62.5mg/ml of Fosnetupitant. The method precision for the determination of assay was below 2.0%RSD. The method is useful in the quality control of bulk and pharmaceutical formulations.
