ADVIL vs BAYER EXTRA STRENGTH ASPIRIN FOR MIGRAINE PAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis, thereby reducing pain, fever, and inflammation.
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.
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day (OTC). For prescription: 400-800 mg orally 3-4 times daily; maximum 3200 mg/day.
500-1000 mg orally every 4-6 hours as needed; maximum 4000 mg in 24 hours.

2-4 hours (terminal elimination half-life in adults; prolonged in overdose or renal impairment: up to 8-12 hours)
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.
Renal: ~95% (hepatic metabolites and conjugates, <1% unchanged); biliary/fecal: ~5%
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.
