MechanismofAcetaminophenActivityandToxicity
Acetaminophen is one of the worlds most commonly used drugs, used for the treatment of pain and fever. Like other NSAIDs (non-steroidal anti-inflammatory drugs), acetaminophen has a unique activity profile based in part on its action at its molecular targets, the cyclooxygenase enzymes that produce prostaglandins responsible for pain, fever and inflammation. Until very recently, only two Cox enzymes, Cox-1 and Cox-2,......阅读全文
