General description

Flunixin is a potent nonsteroidal anti-inflammatory drug, primarily used as an anti-inflammatory agent and analgesic for the short-term treatment of moderate pain and inflammation in farm animals. It is also effective in inhibiting the synthesis of prostaglandins.
Flunixin is classified under the group of non-steroidal anti-inflammatory drugs (NSAIDs).

Application

Flunixin may be used as a reference standard for the determination of NSAID drug, flunixin in biological samples using high-performance liquid chromatography with diode array detection (HPLC-DAD)/particle beam mass spectrometry (PB-MS)/atmospheric pressure ionization mass spectrometry (API-MS) and gas chromatography coupled to mass spectrometry (GC-MS).
Flunixin may be used as an analytical reference standard for the determination of flunixin in:
  • Bovine muscle samples by hydrophilic interaction liquid chromatography-electrospray-tandem mass spectrometry (HILIC-ESI-MS/MS) equipped with selected reaction monitoring (SRM) detection.
  • Animal tissues by dispersive-solid phase extraction (d-SPE) and enhanced matrix removal for lipids (EMR-L), followed by analysis using ultra-high performance liquid chromatography-triple quadrupole or quadrupole-time-of-flight (UHPLC-QqQ or UHPLC-Q/TOF) methods in conjunction with ESI-MS/MS operating on multiple reaction monitoring (MRM) mode of detection as well as ESI-LC-MS/MS with SRM detection mode.
  • Porcine muscle samples by ESI-LC-MS/MS with MRM detection mode.

Recent studies have shown that flunixin prevented recovery of equine jejunum post ischaemia. However, the use of a purported cyclooxygenase (COX)-2 preferential inhibitor, etodolac, also prevented recovery. These findings may have implications for the use of nonsteroidal anti-inflammatory drugs in
