Analytical method for development and validation of Dess-nitro and EDA in Entacapone tablet by using RP-HPLC method
Journal Title: Indian Journal of Research in Pharmacy and Biotechnology - Year 2017, Vol 5, Issue 5
Abstract
A simple, rapid, accurate and reproducible reverse phase high performance liquid chromatography method for the quantitative determination of Dess-nitro and EDA in Entacapone tablets is developed and validated.Entacapone (INN) is a medication commonly used in combination with other medications for the treatment of Parkinson's disease. Entacapone together with levodopa and carbidopa allows levodopa to have a longer effect in the brain and reduces Parkinson’s disease signs and symptoms for a greater length of time than levodopa and carbidopa therapy alone. Chromatography was carried out on a COSMOSIL πNAP column (250×4.6mm, 5µ) in gradient mode. The mobile phase consisted of buffer and methanol, pumped at a flow-rate of 0.8 ml/min. The UV detection was employed at 300nm. The retention time of dess-nitro and EDA was found to be 36.14 and 58.07 minutes respectively. The calibration curves were linear in the range. The method is accurate and precise with recovery of dess-nitro and EDA in the range of 95-105%. The proposed method which is rapid, simple and does not require any separation process has been successfully applied to the assay of commercial fixed dose formulations.
