Acetaminophen by inhibiting the hypothalamus of the temperature regulating center, the synthesis of prostaglandins have antipyretic role, its antipyretic effect similar to aspirin, intensity of the central nervous system by inhibiting prostaglandin synthesis and blocking the nere endings impulse and produce analgesic action, compared with aspirin weak, compared with aspirin, with a small stimulus, the advantages of few allergic reactions, antipyretic analgesic effect and phenacetin, since many countries restrict or ban the use of phenacetin, acetaminophen are increased.
Clinically, it is mainly used for fever caused by cold, headache and relief of mild and moderate pain, such as joint pain, muscle pain, neuralgia, migraine, dysmenorrhea, cancer pain and postoperative analgesia.It can also be used for patients with allergy to aspirin, intolerance or not suitable for aspirin application: for example, patients with varicella, hemophilia and other hemorrhagic diseases (including patients with anticoagulant therapy), and patients with mild peptic ulcer and gastritis;In addition, it can also be used in the synthesis of drugs, as well as organic synthesis intermediate, photographic chemicals and hydrogen peroxide stabilizer.
We can customize according to customer's requirement.
