Sleep-administered ketamine/psychedelics: A streamlined strategy to address two challenges in research on ketamine and psychedelics.

The dissociative effects of ketamine and psychedelics might be associated with their rapid antidepressant properties, raising questions about whether these effects are necessary for their therapeutic action. Additionally, the distinct dissociative experiences often reported by patients in clinical trials may reveal whether they receive an active treatment or a placebo, potentially introducing bias into the results. In this viewpoint, we propose administering ketamine/psychedelics to patients during sleep, offering a novel approach to address and explore these challenges.
