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) enzymes, thereby reducing prostaglandin synthesis, which mediates pain, inflammation, and fever.

50 mg orally twice daily or 75 mg orally once daily; maximum 150 mg/day. Alternatively, 75 mg intramuscularly once daily (short-term).
50 mg intramuscularly every 6 hours as needed for pain; maximum 150 mg per day.

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.
2-4 hours (terminal) in adults; prolonged in elderly (up to 6-8 hours) and hepatic impairment (up to 12 hours).
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%.
Renal: ~50% as unchanged drug and metabolites (glucuronide conjugates); Biliary/fecal: ~40% as metabolites; <5% unchanged in feces.
