Mechanism of action

Paracetamol (acetaminophen) acts primarily as a weak inhibitor of COX-1 and COX-2 enzymes, with preferential central nervous system penetration. This reduces prostaglandin E2 production in the hypothalamus and other CNS regions, lowering the pain threshold and resetting the body's temperature set point. The intravenous formulation provides rapid systemic delivery for acute pain and fever management.
