→Mechanism of action of antipyretic medicines
Inflammatory mediators released by peripheral mononuclear phagocytes and other immune cells induces fever. Fever inducing cytokines are transported from blood to brain. Prostaglandin E2 (PGE2) in the brain is believed to be the principle downstream mediator of fever. Inhibiting the production of PGE2 is a well known mechanism of antipyretics.<ref name=AshokBK>Ashok BK, Ravishankar B, Prajapati PK, Bhat SD.
