Use of paracetamol

Acetaminophen action

this product is an antipyretic and analgesic. It selectively inhibits the synthesis of hypothalamic temperature-regulating central prostagranin by inhibiting coxoidase, leading to peripheral blood tube expansion and sweating to achieve antipyretic effect. Its antipyretic effect is similar to that of aspirin.It plays an analgesic effect by inhibiting the synthesis and release of prostaglandin and raising the pain threshold. It is a peripheral analgesic, which has a weaker effect than aspirin and is only effective for mild and moderate pain.this product has no obvious anti-inflammatory effect.
