Information

Oxyphenbutazone is a nonsteroidal anti-inflammatory drug (NSAID) of the pyrazolidinedione class, formerly used in the treatment of rheumatoid arthritis and other inflammatory conditions. Due to safety concerns, particularly risk of severe adverse hematological reactions such as agranulocytosis, the drug is no longer approved or widely used in clinical practice.

Pharmacokinetics

Pharmacokinetic parameters are reported for healthy adult volunteers (sex not specified) following oral administration.
