Mechanism of action

Acetaminophen works 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 intravenous formulation provides rapid systemic delivery for faster onset of analgesia and antipyresis compared to oral routes. The exact mechanism remains incompletely understood but does not involve significant peripheral anti-inflammatory activity like NSAIDs.
