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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Oral: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/day.
50 mg intramuscularly every 6 hours as needed for pain; maximum 150 mg per day.

Terminal elimination half-life 2-4 hours; prolonged to 6-12 hours in elderly or renal impairment (CrCl <30 mL/min).
2-4 hours (terminal) in adults; prolonged in elderly (up to 6-8 hours) and hepatic impairment (up to 12 hours).
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
Renal: ~50% as unchanged drug and metabolites (glucuronide conjugates); Biliary/fecal: ~40% as metabolites; <5% unchanged in feces.
