BUTAZOLIDIN vs INDOCIN
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.
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever. It also decreases renal blood flow and may cause ductus arteriosus closure.
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.
25 mg orally 2-3 times daily; maximum 200 mg/day. Intravenous: 0.5-1 mg/kg as single dose for ductus arteriosus closure.

Terminal half-life: 50-100 hours (prolonged in elderly or hepatic/renal impairment; accumulation risk evident within 5-7 days).
Terminal elimination half-life approximately 4.5 hours (range 2.6–11.2 hours); prolonged in elderly and patients with hepatic impairment.
Primarily renal: ~60% as unchanged drug and glucuronide conjugates; biliary/fecal: ~40% (enterohepatic circulation).
Renal (60% as unchanged drug and glucuronide conjugates), biliary/fecal (33% via enterohepatic circulation).
