Pharmacology
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 prostacy...

Mechanism of Action: Phenylbutazone binds to and inactivates prostaglandin H synthase and prostacyclin synthase through peroxide (H2O2) mediated deactivation. The reduced production of prostaglandin leads to reduced inflammation of the surrounding tissues.
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
Interactions
Food interaction:
Take with food to reduce irritation. Avoid alcohol.
Drug interaction:
PhenytoinThe NSAID, phenylbutazone, may increase the therapeutic and adverse effects of phenytoin.
DicumarolThe NSAID, phenylbutazone, may increase the anticoagulant effect of dicumarol.
TolazamidePhenylbutazone increases the effect of the hypoglycemic agent
