Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. This leads to 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.
200-400 mg orally every 4-6 hours as needed; maximum daily dose 1200 mg.
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 is approximately 1.5 to 2 hours in infants and children, which is shorter than in adults (2-4 hours). This shorter half-life reflects higher clearance in pediatric populations and has clinical implications for dosing frequency (typically every 6-8 hours).
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 excretion of metabolites (primarily glucuronide and sulfate conjugates of ibuprofen) accounts for approximately 90% of elimination, with less than 10% excreted unchanged in urine. Biliary/fecal excretion is minimal (<5%).
Primarily hepatic metabolism; renal excretion of metabolites (<1% unchanged). Biliary/fecal excretion accounts for ~20% of total elimination.
