DETAILS

DrugBank - DB00812

• Drug Groups: approved
• Description: A drug that has anti-inflammatory, antipyretic, and analgesic activities. It is especially effective in the treatment of ankylosing spondylitis. It also is useful in rheumatoid arthritis and Reiter's syndrome (investigational indication). Although phenylbutazone is effective in gouty arthritis, risk/benefit considerations indicate that this drug should not be employed for this disease. (From AMA Drug Evaluations Annual, 1994, p1822)
• Indication: For the treatment of backache and ankylosing spondylitis
• Pharmacology: Phenylbutazone is a synthetic, pyrazolone derivative. It is a nonhormonal anti-inflammatory, antipyretic compound useful in the management of inflammatory conditions. The apparent analgesic effect is probably related mainly to the compound's anti-inflammatory properties and arise from its ability to reduce production of prostaglandin H and prostacyclin. Prostaglandins act on a variety of cells such as vascular smooth muscle cells causing constriction or dilation, on platelets causing aggregation or disaggregation and on spinal neurons causing pain. Prostacylcin causes vascular constriction platelet disaggregation
• Toxicity: Oral, LD₅₀ = 238 mg/kg (mouse); Oral, LD₅₀ = 781 mg/kg (rabbit); Oral, LD₅₀ = 245 mg/kg (rat); Oral, LD₅₀ = 375 mg/kg (rat)
• Affected Organisms: Humans and other mammals

Research Area: Inflammation
Biological Activity:
Phenylbutazone(Butazolidin, Butatron) is used as a non-steroidal anti-inflammatory agent for the treatment of chronic pain, including the symptoms of arthritis. Its use is limited by such severe side effects as suppression of white blood cell production and aplastic anemia. [1]
