Acetaminophen, a centrally-acting analgesic involving the periaqueductal grey.
Authors
Abstract
We previously demonstrated that acetaminophen (AcAP) has to be metabolized in the brain by fatty acid amide hydrolase enzyme (FAAH) into AM404 (N-(4-hydroxyphenyl)-5Z,8Z,11Z,14Z-eicosatetraenamide) to recruit CB1 and TRPV1 receptors, responsible for its analgesic effect. However, the brain mechanisms supporting AcAP-induced analgesia remain unknown.
