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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby exerting anti-inflammatory, analgesic, and antipyretic effects. Sulindac is a prodrug converted to the active sulfide metabolite.
One caplet (ibuprofen 250 mg and acetaminophen 500 mg) orally every 8 hours while symptoms persist; maximum: 3 caplets per day.
150-200 mg orally twice daily, with maximum daily dose of 400 mg.

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).
7.8 hours (terminal); clinical context: prolonged in elderly and renal impairment, requiring dose adjustment.
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: 50% as unchanged drug, 25% as glucuronide conjugate; Biliary/Fecal: 25% as metabolites.
