BAYER EXTRA STRENGTH ASPIRIN FOR MIGRAINE PAIN vs CHILDREN'S MOTRIN
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 (COX-1 and COX-2), reducing prostaglandin synthesis, thereby decreasing pain, fever, and inflammation.
500-1000 mg orally every 4-6 hours as needed; maximum 4000 mg in 24 hours.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day without prescription, extended release forms: 600-800 mg orally twice daily.

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 in children; prolonged in neonates and hepatic 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 (90%) as inactive metabolites and conjugates; fecal (<5%).
