Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Irreversibly acetylates cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), inhibiting prostaglandin and thromboxane A2 synthesis, leading to analgesic, antipyretic, anti-inflammatory, and antiplatelet effects.
Non-selective inhibitor of cyclooxygenase (COX-1 and COX-2), decreasing prostaglandin synthesis, resulting in anti-inflammatory, analgesic, and antipyretic effects.
325-650 mg every 8 hours for pain/fever; 81-325 mg daily for cardiovascular prophylaxis.
200-400 mg orally every 4-6 hours, maximum 1200 mg/day; for OTC use, 200-400 mg every 6-8 hours as needed, maximum 1200 mg/day.

15-20 hours (terminal elimination half-life) for salicylate at therapeutic concentrations; prolonged to 20-30 hours at high doses due to saturation of hepatic metabolism (zero-order kinetics).
2.0-2.5 hours (terminal); no prolongation in mild hepatic impairment; increased in renal failure.
Renal excretion of conjugated salicylate metabolites (75% as salicyluric acid, 10% as salicyl phenolic glucuronide, 5% as salicyl acyl glucuronide, 5% as gentisic acid); 10% free salicylate; approximately 10% eliminated in feces via bile.
Renal: 90% as metabolites and conjugates, <1% unchanged; biliary/fecal: minor.
