CAS 103-90-2: Acetaminophen

Description: Acetaminophen, also known as paracetamol, is a widely used analgesic and antipyretic medication. Its chemical formula is C8H9NO2, and it features a phenolic hydroxyl group and an amide functional group, which contribute to its therapeutic properties. Acetaminophen is typically administered orally, but it can also be given intravenously or rectally. It is known for its ability to relieve mild to moderate pain and reduce fever, making it a common choice for treating headaches, muscle aches, arthritis, and colds. Unlike nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen does not possess significant anti-inflammatory properties. Its mechanism of action is believed to involve the inhibition of cyclooxygenase enzymes, particularly in the brain, leading to decreased production of prostaglandins. While generally considered safe when used as directed, excessive doses can lead to severe liver damage. Acetaminophen is often included in combination medications and is available over-the-counter in various formulations, including tablets, capsules, and liquid forms.
