Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Irreversibly inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing prostaglandin and thromboxane synthesis, which leads to analgesic, antipyretic, and anti-inflammatory effects.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.
500-1000 mg orally every 4-6 hours as needed; maximum 4000 mg in 24 hours.
220-550 mg orally twice daily; maximum 1375 mg/day.

Aspirin half-life is 15-20 minutes due to rapid hydrolysis to salicylate. Salicylate terminal half-life is 2-3 hours at low doses, up to 15-30 hours at high doses or with toxicity. At analgesic doses (600-1000 mg), effective half-life is ~3-4 hours, requiring q4-6h dosing.
12–17 hours (terminal); allows twice-daily dosing; prolonged in elderly and renal impairment
Renal excretion of salicylate and its metabolites (salicyluric acid, salicyl phenolic glucuronide, salicyl acyl glucuronide, gentisic acid). Approximately 90% of a dose is excreted renally; 10% via bile/feces. Excretion is dose- and pH-dependent: alkaline urine increases clearance.
Renal: 95% (as unchanged drug, conjugated naproxen, and 6-O-desmethyl naproxen); Fecal: <5%
