General description
Flunixin is classified under the group of non-steroidal anti-inflammatory drugs (NSAIDs).
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.
Application
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.
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).

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
