Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cyclooxygenase (COX) inhibitor, reducing prostaglandin synthesis; nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic, and antipyretic effects.
Phenylbutazone is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis, thereby causing anti-inflammatory, analgesic, and antipyretic effects. It also inhibits leukocyte migration and lysosomal enzyme release.
Oral: 50-100 mg every 6-8 hours; maximum 300 mg/day. Ophthalmic: 1 drop every 30 minutes starting 2 hours before surgery, then 1 drop every 4-6 hours for 24-48 hours post-surgery.
Oral: 100-200 mg three times daily with food; maximum 600 mg/day. For acute gout: initial 400 mg followed by 200 mg every 4-6 hours for 1-2 days, then reduce.

Terminal elimination half-life: 3-4 hours (healthy adults) in short-term use; prolonged to 6-12 hours in elderly or renal impairment.
Terminal elimination half-life is 50–65 hours, but exhibits dose-dependent kinetics; can extend to 72–100 hours with repeated dosing or in elderly.
Renal: 70% as conjugated metabolites (e.g., glucuronides) and <5% unchanged; biliary/fecal: 30%, with enterohepatic circulation.
Primarily hepatic metabolism; renal excretion of metabolites (<1% unchanged). Biliary/fecal excretion accounts for ~20% of total elimination.
