Description

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, a more recent study indicates that this compound inhibits COX-2 activity by more than 80%, albeit at relatively high doses, while it is less effective against COX-1. Acetaminophen is enzymatically and non-enzymatically converted to several reactive metabolites that contribute to adverse or indirect effects, including liver injury. Acetaminophen is reportedly used a cutting agent in heroin.
