Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen, a nonsteroidal anti-inflammatory drug (NSAID), inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This leads to decreased inflammation, pain, and fever.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin synthesis, leading to anti-inflammatory, analgesic, and antipyretic effects.
220 mg orally every 8 to 12 hours as needed; maximum 660 mg per day.
Oral: 50 mg three times daily or 75 mg twice daily; maximum 300 mg/day. Topical: Apply 2-4 g of gel or cream to affected area four times daily. Intramuscular: 50-100 mg every 4-6 hours; maximum 200 mg/day.

Terminal elimination half-life is 12-17 hours; allows twice-daily dosing for steady-state concentrations.
Terminal half-life: ~1.5-2 hours for immediate-release; 30-50% increase in elderly due to reduced clearance. Clinical context: short half-life requires frequent dosing for sustained analgesia; no accumulation with q6-8h dosing.
Renal (95% as unchanged drug and metabolites); biliary/fecal (5%)
Renal: ~60% as metabolites (glucuronides of ketoprofen and hydroxylated metabolites); fecal: ~30% (biliary excretion); unchanged drug: <1% in urine.
