Application

Phenylbutazone has been used:
  • as a hepatotoxin in transgenic zebrafish line (LiPan) hepatotoxin assay
  • as a standard in high-performance liquid chromatography-ultraviolet (HPLC-UV) method
  • as an anti-inflammatory compound in hen′s egg chorioallantoic membrane test (HET-CAM assay)

Biochem/physiol Actions

Phenylbutazone is a hepatotoxin and binds to plasma proteins. It is used to treat inflammation in horse. Phenylbutazone has potential to treat ankylosing spondylitis. It has therapeutic potential to treat myotonic dystrophy type 1 (DM1) by inducing muscle blind-like protein 1 (MBNL1) expression. It also favors the expression of muscle chloride channel in skeletal muscles.

Substrates

Non-steroidal anti-inflammatory compound; inhibitor of cyclooxygenase that is also a substrate for peroxidation by cyclooxygenase.

Objective blinded efficacy data during exercise are lacking on the use of single-dose i.v. nonsteroidal anti-inflammatory drugs (NSAIDs) before, during and after exercise. Single i.v. doses of either phenylbutazone (PBZ) or flunixin meglumine (FM) would prove more efficacious than negative
