Usage: Paracetamol is a medicine that exerts analgesic (reduces pain) and antipyretic (reduces fever) activity, but does not possess anti-inflammatory activity. Paracetamol is used for fast effective, temporary relief of pain and discomfort associated with headache, period pain, cold&flu,tension headache, backache, muscular aches, arthritis/osteoarthritis, toothache,migraine and also reduces fever.
Acetaminophen is an analgesic and antipyretic compound. Unlike many NSAIDs, which inhibit both COX-1 and COX-2, early studies suggested that acetaminophen is a poor inhibitor of both isoforms. However, it does inhibit COX-2 by 83% and COX-1 by 56% in human blood ex vivo, albeit at a high 1,000 mg dose, with IC50 values of 25.8 and 113.7 µM, respectively. Acetaminophen is enzymatically and non-enzymatically converted to several reactive metabolites that contribute to adverse or indirect effects, including liver injury. At toxic doses, the acetaminophen metabolite N-acetyl-4-benzoquinone imine (NAPQI, Cay-16115) depletes glutathione reserves in the liver, leading to an accumulation of NAPQI and subsequent hepatocyte necrosis. Acetaminophen decreases glutathione levels and reduces glutathione peroxidase activity in mice when administered at a dose of 250 mg/kg and induces ferroptotic cell death in primary mouse hepatocytes, an effect that can be blocked by the ferroptosis inhibitor ferrostatin-1 (Cay-17729). Acetaminophen has analgesic and antipyretic properties in animal models. Formal Name: N-(4-hydroxyphenyl)-acetamide. CAS Number: 103-90-2.
