Acetaminophen is an organic compound with the chemical formula C8H9NO2. It is a metabolite of phenacetin in the body, which inhibits the synthesis and release of prostaglandin PGE1, bradykinin, and histamine by inhibiting the hypothalamic thermoregulatory center prostaglandin synthase. PGE1 mainly acts on the central nervous system, and its reduction will lead to a decrease in the central body temperature setting point. The surface temperature receptors feel relatively hot, which in turn causes peripheral vascular dilation and sweating through neural regulation to achieve antipyretic effects. Its inhibitory effect on central nervous system prostaglandin synthesis is similar to aspirin, but its anti-inflammatory effect is weak. It has no effect on platelets and coagulation mechanisms.

ApplicationUsed for cold fever, joint pain, neuralgia, migraine, cancerous pain, and postoperative pain relief. It can also be used in patients who are allergic, intolerant, or unsuitable for the use of aspirin (such as chickenpox, hemophilia, and other hemorrhagic diseases).
