Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis; also inhibits leukotriene synthesis and has direct membrane-stabilizing effects.
550 mg orally every 8 to 12 hours; maximum 1375 mg/day.
Oral: 75 mg three times daily or 50 mg four times daily; maximum 300 mg/day. Intravenous: 100 mg every 12-24 hours, infused over 15-30 minutes.

Terminal elimination half-life is approximately 12–17 hours (mean ~14 hours), allowing twice-daily dosing. Steady-state is achieved after 4–5 doses.
Clinical Note
moderateKetoprofen + Gatifloxacin
"Ketoprofen may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateKetoprofen + Rosoxacin
"Ketoprofen may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateKetoprofen + Levofloxacin
"Ketoprofen may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateKetoprofen + Trovafloxacin
"Ketoprofen may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life: 2-4 hours; clinical context: short half-life allows for quick drug clearance but requires frequent dosing; may be prolonged in elderly or renal impairment.
Renal elimination of naproxen and its metabolites accounts for approximately 95% of the dose, with about 60% as unchanged drug and 40% as conjugated or hydroxylated metabolites. Biliary/fecal excretion is negligible (<5%).
Renal: ~80% (60% as glucuronide conjugates, 20% as unchanged drug); Biliary/Fecal: ~20% via bile.
