Paracetamol(Acetaminophen):
The antipyretic and analgesic acetaminophen, this product is a metabolite of phenacetin, regulates central prostaglandin synthase by inhibiting hypothalamic body temperature. Reduce the synthesis and release of prostaglandin PGE1, bradykinin and histamine. PGE1 mainly acts on the nerve center. Its decrease will lead to a decrease in the central body temperature setting point, and the body surface temperature sensor will feel relatively hot, and then through nerve regulation, it will cause peripheral blood vessels to dilate and sweat to achieve antipyretic effect, which inhibits the central nervous system. The effect of prostaglandin synthesis is similar to that of aspirin, but its anti-inflammatory effect is weak. No effect on platelets and coagulation mechanism. Indications: Used for cold and fever, joint pain, neuralgia, migraine, cancer pain and postoperative pain relief.
