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) enzymes, reducing prostaglandin synthesis. It has anti-inflammatory, analgesic, and antipyretic effects.
One caplet (ibuprofen 250 mg and acetaminophen 500 mg) orally every 8 hours while symptoms persist; maximum: 3 caplets per day.
400 mg orally three times daily; maximum 1800 mg/day.

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).
Terminal elimination half-life is approximately 4.5–6 hours (mean 5 hours); may be prolonged in elderly or patients with renal 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 excretion (~90% as unchanged drug and conjugates), with fecal excretion (~10% as metabolites)
