BUTAZOLIDIN vs INFANT'S ADVIL
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 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.
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.
200-400 mg orally every 4-6 hours as needed; maximum daily dose 1200 mg.

Terminal half-life: 50-100 hours (prolonged in elderly or hepatic/renal impairment; accumulation risk evident within 5-7 days).
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).
Primarily renal: ~60% as unchanged drug and glucuronide conjugates; biliary/fecal: ~40% (enterohepatic circulation).
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%).
