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), reducing prostaglandin synthesis, thereby decreasing pain, fever, and inflammation.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis, which mediates pain, inflammation, and fever.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day without prescription, extended release forms: 600-800 mg orally twice daily.
50 mg orally twice daily or 75 mg orally once daily; maximum 150 mg/day. Alternatively, 75 mg intramuscularly once daily (short-term).

2-4 hours in children; prolonged in neonates and hepatic impairment.
Terminal elimination half-life is ~1.1 hours (range 0.9–1.6 h). Short half-life supports frequent dosing (e.g., every 6–8 hours) for sustained analgesia.
Renal (90%) as inactive metabolites and conjugates; fecal (<5%).
Approximately 50% of a dose is eliminated via first-pass hepatic metabolism; renal excretion accounts for ~65% of the administered dose as metabolites (<1% unchanged drug); fecal excretion <20%.
