Novel electrochemical quantification for nepafenac in raw drug, pharmaceutical eye drops and biological fluid
Journal Title: World Journal of Pharmaceutical Sciences - Year 2018, Vol 6, Issue 6
Abstract
This article pronounces differential pulse voltammetric technique for the determination of nepafenac in pharmaceutical dosage form and human serum. The proposed voltammetric technique was established on electro-oxidation of nepafenac at two electrodes, the first electrode is the carbon paste modified with 10% w/w of 1-n-butyl-3-methylpyridinium hexafluorophosphate ion crystal (10%BMH-CPE) and the second electrode is carbon paste modified with 10% w/w of each of multi walled carbon nanotubes and 1-n-butyl-3-methylpyridinium hexafluorophosphate (CMWNT-BMH-CPE).The method was performed in 0.04M B-R electrolyte with pH=6.0. The peak current concentration relationship was linearand the suggested methods were applied successfully to the pharmaceutical dosage form and spiked human serum with good repeatability and reproducibility.
