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, reducing 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.
220-550 mg orally twice daily; maximum 1375 mg/day.

Terminal half-life: 50-100 hours (prolonged in elderly or hepatic/renal impairment; accumulation risk evident within 5-7 days).
12–17 hours (terminal); allows twice-daily dosing; prolonged in elderly and renal impairment
Primarily renal: ~60% as unchanged drug and glucuronide conjugates; biliary/fecal: ~40% (enterohepatic circulation).
Renal: 95% (as unchanged drug, conjugated naproxen, and 6-O-desmethyl naproxen); Fecal: <5%
