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-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis involved in pain, inflammation, and fever.
Oral: 400 mg every 4-6 hours as needed for pain; maximum 1200 mg/day.
Oral: 200-400 mg every 4-6 hours as needed; maximum single dose 400 mg, maximum daily dose 1200 mg for OTC use.

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 2-4 hours in children; prolonged in neonates or hepatic impairment.
Renal: 90% as unchanged drug; biliary/fecal: 10% as metabolites.
Renal excretion of conjugated metabolites (approximately 70-90%) and unchanged drug (<10%). Biliary/fecal excretion accounts for <10%.
