摘要
The use of (Netupitant and Palonosetron) combination to treat nausea and vomiting in cancer chemotherapy patients has been authorized by the Food and Drug Administration. For the simultaneous determination of Netupitant (NET) and palonosetron (PAL) in the presence of two of their related substances and in their dosage form, a sensitive and selective RP-HPLC method has been developed and validated. The aforementioned medications were separated and quantified with the help of experimental design. The Box-Behnken design was used in the experiment to optimize the chromatographic method’s analytical parameters. It employed RP-HPLC with a UV detector. Waters ODS-C18 column (3.5 µm, 75 × 4.6 mm) with a mobile phase composed of acetonitrile: 25 mM phosphate buffer (pH = 3.5) in a gradient mode at 254 nm was employed to separate the cited drugs and their impurities. Palonosetron was linear over the concentration range (1–50 µg/mL) and Netupitant (10–100 µg/mL). According to ICH guidelines, the new method underwent thorough validation. Between the proposed method’s results and those from the reported method, there was no significant difference. It is easy to apply the technique to the analysis of the specified drugs in their combination dosage form for quality control considerations.
