Acetaminophen Powder CAS 103-90-2 Use
1. Medical field:
Antipyretic and analgesic: As an over-the-counter drug, it is widely used to relieve mild to moderate symptoms such as headache, muscle pain, joint pain, and fever caused by colds. It achieves the antipyretic effect by inhibiting the prostaglandin synthase in the hypothalamic thermoregulatory center, reducing the synthesis and release of prostaglandin PGE, and causing peripheral vascular dilation and sweating. It can also exert analgesic effects by inhibiting the synthesis and release of prostaglandin PGE1, bradykinin and histamine, etc., and increasing the pain threshold, but it is ineffective for various severe pains and visceral smooth muscle colic.
Suitable for special groups: Patients who are allergic to, intolerant to or not suitable for aspirin use, such as those with chickenpox, hemophilia and other bleeding disorders (including those undergoing anticoagulant therapy), as well as patients with mild peptic ulcers and gastritis, etc., can choose acetaminophen.
Postoperative pain management: It is often used in combination with opioid drugs to reduce the dosage of opioids and minimize side effects. However, the recommended dosage varies depending on individual differences and the type of surgery, and should be used under the guidance of a doctor.
Chronic pain treatment: For chronic pain such as osteoarthritis and fibromyalgia, it can be part of long-term treatment to help control the pain. However, when used for a long time, liver function should be monitored regularly to avoid exceeding the maximum recommended dose.
Drug synthesis: It can be used in the synthesis of the drug pyrethromycin.
2. Other uses: It can be used as an organic synthesis intermediate, a stabilizer for hydrogen peroxide, a chemical for photography, etc.

High-dose administration may also cause nausea, vomiting, stomach pain, stomach cramps, diarrhea, anorexia, excessive sweating, etc.
Special population risk: Children under 3 years old have underdeveloped liver and kidney functions and poor detoxification and excretion functions. Their use should be avoided as much as possible. In addition, patients with impaired liver or kidney function and pregnant women should use it with caution.
Hazardous materials signs and instructions: The hazard symbols include Xn (Hazardous substances), T (toxic), F (flammable), and the hazard descriptions include R22 (harmful if swallowed), R36/37/38 (irritating to eyes, respiratory system and skin), etc.
Safety Instructions: S26 (In case of contact with eyes, rinse immediately with plenty of water and seek medical advice), S36/37/39 (Wear appropriate protective clothing, gloves, goggles or mask), S61 (Avoid release into the environment. Refer to special instructions/safety data sheet).
