An analysis of the FDA Adverse Event Reporting System found that reports of hepatobiliary disorders differ between ketamine and esketamine. Compared to acetaminophen, ketamine was associated with disproportionately lower reporting of hepatitis, liver injury, drug-induced liver injury, hepatic failure, and acute hepatic failure, but disproportionately higher reporting of hepatic function abnormalities and hepatic cytolysis. For esketamine, there was no disproportionate reporting of most hepatobiliary toxicities relative to acetaminophen, except for disproportionately higher reporting of hepatic failure. The authors recommend periodic monitoring of liver function tests and clinical surveillance for signs of hepatobiliary disease in individuals receiving chronic ketamine or esketamine, though causality has not been established.
