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.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor; reduces prostaglandin synthesis.
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.
400-800 mg orally every 6-8 hours as needed; maximum 3200 mg/day.

Terminal half-life: 50-100 hours (prolonged in elderly or hepatic/renal impairment; accumulation risk evident within 5-7 days).
The terminal elimination half-life is 2-4 hours in adults with normal renal function. In elderly patients or those with renal impairment, half-life may be prolonged up to 8-12 hours, requiring dose adjustment.
Primarily renal: ~60% as unchanged drug and glucuronide conjugates; biliary/fecal: ~40% (enterohepatic circulation).
Renal excretion of unchanged drug accounts for approximately 70-90% of the administered dose, with the remainder eliminated as glucuronide conjugates in urine. Biliary/fecal elimination is minimal (<5%).
