The Introductction of Acetaminophen:


Acetaminophen is an acetanilid antipyretic analgesic. By inhibiting cyclooxygenase, selectively inhibiting the synthesis of prostaglandin in the hypothalamic body temperature regulation center, leading to peripheral vasodilation and sweating to achieve antipyretic effect, the intensity of antipyretic effect is similar to aspirin; by inhibiting the synthesis of prostaglandins, etc. And release, increase the pain threshold and play an analgesic role, which belongs to peripheral analgesics, the effect is weaker than aspirin, only effective for mild to moderate pain.


The Application & Function of Acetaminophen:


Function :

1.Paracetamol is the most commonly used non-anti-inflammatory antipyretic analgesics, antipyretic effect similar analgesic effect is weak, no anti-inflammatory anti-rheumatic effects, acetanilide drugs is the best varieties. Particularly suitable for patients who can not use carboxylic acids. For cold, toothache embolism. Acetaminophen is also an intermediate for organic synthesis, hydrogen peroxide stabilizer, and photographic chemicals.


2.Paracetamol for antipyretic, analgesic, anti-rheumatic drugs


3.Paracetamol for organic synthesis intermediates, hydrogen peroxide stabilizer, photographic chemicals, non-anti-inflammatory antipyretic analgesics.




Paracetamole is approved for reducing fever in people of all ages. Paracetamole is used for the relief of pains associated with many parts of the body. It has analgesic properties comparable to those of aspirin, while its anti-inflammatory effects are weaker. It is better tolerated than aspirin in patients in whom excessive gastric acid secretion or prolongation of bleeding time may be a concern.
