Bromfenac sodium is an anti-inflammatory analgesic NSAID. This book validates the direct measurement of Bromfenac at two carbon paste electrodes modified with multiwalled carbon nanotubes and 1-n-butyl-3-methylpyridinium hexafluorophosphate liquid ion crystals along with their bare carbon paste electrode, where the electrodes revealed high sensitivity and selectivity in voltammetric measurements of pure form, pharmaceutical dosage form and rabbit aqueous humor.
