Mechanism of action

This is a combination used in anesthesia and acute psychiatric settings. Haloperidol is a typical antipsychotic that antagonizes dopamine signaling in the mesolimbic and mesocortical pathways, reducing hallucinations and delusions. Ketamine is a dissociative anesthetic and NMDA receptor antagonist that produces rapid sedation, analgesia, and dissociation, often used to complement antipsychotic therapy in acute agitation or psychotic crises requiring sedation.
