Mechanism of action

Acetaminophen is believed to work primarily through inhibition of cyclooxygenase (COX) enzymes in the brain and spinal cord, reducing prostaglandin production and thereby lowering the pain threshold and resetting the hypothalamic thermostat. The exact mechanism remains incompletely understood, but it does not significantly inhibit peripheral COX enzymes like NSAIDs do. Both intravenous and oral formulations deliver the same active compound with similar mechanisms of action, though IV administration provides faster onset.
