ACETAMINOPHEN AND IBUPROFEN vs CHILDREN'S ADVIL-FLAVORED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetaminophen is a centrally acting analgesic and antipyretic whose exact mechanism is not fully understood, but is thought to involve inhibition of cyclooxygenase (COX) in the brain and modulation of cannabinoid receptors. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that non-selectively inhibits COX-1 and COX-2, reducing prostaglandin synthesis.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, resulting in antipyretic, analgesic, and anti-inflammatory effects.
Oral: Acetaminophen 325 mg and ibuprofen 200 mg, 1-2 tablets every 6 hours as needed, not exceeding 6 tablets/24 hours.
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription, up to 3200 mg/day under medical supervision.

Acetaminophen: 2-3 hours (normal hepatic function). Ibuprofen: 2-4 hours (immediate-release); prolonged in overdose or hepatic impairment.
2-4 hours in children; prolonged in neonates (up to 30 hours) and hepatic impairment.
Acetaminophen: renal excretion of metabolites (glucuronide 55%, sulfate 30%, cysteine/mercapturate <10%); <5% unchanged. Ibuprofen: renal excretion of metabolites (conjugates) 90%; <10% unchanged; minor biliary/fecal.
Renal excretion of conjugated metabolites (75-80% as glucuronide and sulfate conjugates, <10% as unchanged drug); biliary/fecal elimination accounts for <5%.
