How Is Ketamine Metabolized?

Ketamine is not directly eradicated from the body in a similar form. The research on it shows that this drug, when it reaches the liver of the consumer, gets metabolized. However, the metabolites are less strong and have varied half-lives. That is why the period for Ketamine’s or its metabolites stay in the body varies. 

Resources say that the resulting metabolites have far briefer half-lives. Nevertheless, people suffering from liver dysfunction have not been prescribed this drug.
