Mechanism of action

Acetaminophen works primarily through inhibition of cyclooxygenase (COX) enzymes in the brain and spinal cord, reducing prostaglandin production and thereby lowering pain perception and body temperature set point. The intravenous formulation provides rapid systemic delivery for faster onset of analgesia and antipyresis compared to oral routes. It does not have significant peripheral anti-inflammatory activity like NSAIDs.
