Mechanism of action

Acetaminophen is believed to work primarily through inhibition of cyclooxygenase (COX) enzymes in the brain and spinal cord, reducing the production of prostaglandins that mediate pain and fever signaling. Unlike NSAIDs, it has minimal peripheral anti-inflammatory effects. The exact mechanism remains incompletely understood, but central nervous system effects on pain perception and thermoregulation are primary.
