Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin synthesis. Also has uricosuric effect at higher doses.
Ibuprofen lysine is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This results in anti-inflammatory, analgesic, and antipyretic effects.
Butazolidin (phenylbutazone) is typically administered orally at 100-200 mg 3 times daily with meals, not to exceed 600 mg/day. Initial loading dose of 400 mg may be given on day 1, followed by 300-400 mg/day in divided doses. Duration should be limited to 7-10 days.
200-800 mg orally every 6-8 hours as needed; maximum 2400 mg/day. Intravenous: 400-800 mg every 6 hours; maximum 3.2 g/day.

Terminal half-life: 50-100 hours (prolonged in elderly or hepatic/renal impairment; accumulation risk evident within 5-7 days).
2–4 hours in adults; extended to 4–6 hours in neonates. In severe hepatic or renal impairment, half-life may increase up to 8–10 hours.
Primarily renal: ~60% as unchanged drug and glucuronide conjugates; biliary/fecal: ~40% (enterohepatic circulation).
Renal excretion of metabolites and conjugates accounts for >90% of elimination; less than 1% is excreted unchanged in urine. Fecal excretion is minimal (<5%).
