Ketamine Improves Sleep and Reduces Suicidal Thoughts in Certain Patients

ketamine may improve sleep

Intravenous ketamine is known for its fast-acting antidepressant effects, which can appear within two hours of an infusion. Researchers are now investigating its use for the reduction of suicidal thoughts. In a study presented in a poster at the 2015 meeting of the Society of Biological Psychiatry, Jennifer L. Vande Voort and colleagues compared the sleep of patients whose suicidal thoughts decreased after a single ketamine infusion (0.5 mg/kg over 40 minutes) to those whose suicidal thoughts remained.

Study participants whose suicidal thoughts diminished after one infusion of ketamine had better sleep quality the following night, with fewer disruptions in sleep than among those who did not have an anti-suicidal response to ketamine. The participants who responded well to ketamine had sleep quality similar to that of healthy controls.

Vande Voort and colleagues hope that these new findings about ketamine’s effect on sleep may provide clues to the biological mechanism behind ketamine’s effect on suicidal ideation.
