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 cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever.
325-650 mg every 8 hours for pain/fever; 81-325 mg daily for cardiovascular prophylaxis.
200–400 mg orally every 4–6 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).
1.8 to 2.5 hours. The short half-life supports dosing every 4 to 6 hours for acute pain and fever.
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 excretion of metabolites and conjugates accounts for approximately 90% of an administered dose. Less than 1% is excreted unchanged. Biliary/fecal elimination accounts for about 10%.
