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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
500-1000 mg orally every 4-6 hours as needed; maximum 4000 mg in 24 hours.
50 mg intramuscularly every 6 hours as needed for pain; maximum 150 mg per 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.
2-4 hours (terminal) in adults; prolonged in elderly (up to 6-8 hours) and hepatic impairment (up to 12 hours).
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: ~50% as unchanged drug and metabolites (glucuronide conjugates); Biliary/fecal: ~40% as metabolites; <5% unchanged in feces.
