Products Description of Acetaminophen CAS#103-90-2

Acetaminophen is an analgesic/antipyretic that inhibits COX-2 (83%) and COX-1 (56%) at high 1,000 mg doses. Its toxic metabolite NAPQI causes liver injury by depleting glutathione, and it induces ferroptosis in mouse hepatocytes (reversible by ferrostatin-1). It remains effective for pain and fever relief in animal studies.
