Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. Acetaminophen is an analgesic and antipyretic whose mechanism is not fully understood but involves inhibition of cyclooxygenase in the central nervous system and modulation of the endocannabinoid system.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
One caplet (ibuprofen 250 mg and acetaminophen 500 mg) orally every 8 hours while symptoms persist; maximum: 3 caplets per day.
Oral: 200-400 mg every 6-8 hours as needed; maximum daily dose: 1200 mg (OTC) or 3200 mg (prescription).

Ibuprofen: 2-4 hours; Acetaminophen: 2-3 hours. Clinical context: Short half-lives require dosing every 6-8 hours. Extended half-life in overdose (acetaminophen >4 hours indicates toxicity).
2-4 hours (terminal elimination half-life in children; may be prolonged in neonates or hepatic impairment)
Ibuprofen: renal (90% as metabolites and conjugates, <10% unchanged); Acetaminophen: renal (85% as sulfate and glucuronide conjugates, 4% unchanged, 9% as cysteine and mercapturic acid conjugates; minor biliary).
Renal: 90% (primarily as conjugated metabolites, <10% unchanged); biliary/fecal: minor
