Mechanism of action

Acetaminophen is a non-opioid analgesic and antipyretic that works primarily through inhibition of cyclooxygenase (COX) enzymes in the brain and spinal cord, reducing prostaglandin production. This leads to decreased pain perception and lowering of the body's temperature set point. The exact mechanism remains incompletely understood, but it does not significantly inhibit peripheral COX enzymes like NSAIDs do.
