Paracetamol:
powder nutritional supplemen Mainly used for amino acid infusion,due to special wettability, also used in cold cream,osmetics. Serine constitute the human body of several kinds of essential amino acid of protein a, for the construction of protein has a very important role. 
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. This product can also be used for patients who are allergic to aspirin, intolerant or not suitable for aspirin (chickenpox, hemophilia and other bleeding disorders, etc.).

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.
