Introduction and property
Introduction
The chemical name of acetaminophen is N-(4-Hydroxyphenyl)acetamide (N-(4-Hydroxyphenyl)acetamide), and its trade name is paracetamol, which belongs to the acetanilide class of antipyretic and analgesics. It was first synthesized by Morse in 1878 and first used clinically by Von Mering in 1893. It became an over-the-counter drug in the United States in 1955, and production began in my country at the end of the 1950s. Its appearance is white crystal or crystalline powder, with a melting point of 168-172°C, odorless, slightly bitter taste, easily soluble in hot water or ethanol, soluble in acetone, and almost insoluble in cold water and petroleum ether.
Property
Acetaminophen acts as an antipyretic by inhibiting the synthesis of prostaglandins in the hypothalamic thermoregulatory center. Its antipyretic effect is similar to that of aspirin. It is produced by inhibiting the synthesis of prostaglandins in the central nervous system and blocking the impulses of pain nerve endings. It has an analgesic effect that is weaker than that of aspirin. Compared with aspirin, it has the advantages of less irritation and less allergic reactions. Its antipyretic and analgesic effect is similar to that of phenacetin.
