Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetaminophen (paracetamol) is a non-opioid analgesic and antipyretic. Its mechanism is not fully understood but involves inhibition of cyclooxygenase (COX) enzymes in the central nervous system, reducing prostaglandin synthesis. It also modulates the endocannabinoid system and serotonergic pathways.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. This leads to anti-inflammatory, analgesic, and antipyretic effects.
Oral: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/day.
Ibuprofen 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.

Terminal elimination half-life 2-4 hours; prolonged to 6-12 hours in elderly or renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 2-4 hours in children. Clinical context: rapid clearance; requires frequent dosing every 6-8 hours for sustained antipyretic/analgesic effect.
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
Renal excretion of conjugated metabolites (glucuronides and sulfates) accounts for >90% of an administered dose, with <1% excreted unchanged. Biliary/fecal elimination is minimal (<5%).
