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-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing inflammation and pain.
One caplet (ibuprofen 250 mg and acetaminophen 500 mg) orally every 8 hours while symptoms persist; maximum: 3 caplets per day.
120 mg administered intravenously over 15 minutes, followed by 30 mg intravenously over 15 minutes, with the second dose given 12 to 24 hours after the first dose.

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 1.5-2.5 hours in healthy adults. In elderly or renally impaired patients, half-life may extend to up to 6 hours.
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).
Approximately 70% renal (30% unchanged, 40% as glucuronide conjugate), 30% fecal/biliary.
