Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acetaminophen (paracetamol) is a non-opioid analgesic and antipyretic. Its mechanism is not fully understood but involves inhibition of cyclooxygenase (COX) enzymes in the central nervous system, reducing prostaglandin synthesis. It also modulates the endocannabinoid system and serotonergic pathways.
Non-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing inflammation and pain.
Oral: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/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.

Terminal elimination half-life 2-4 hours; prolonged to 6-12 hours in elderly or renal impairment (CrCl <30 mL/min).
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.
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
Approximately 70% renal (30% unchanged, 40% as glucuronide conjugate), 30% fecal/biliary.
