Fast-acting benefits of ketamine for depression and suicidality


A nasal spray formulation of ketamine shows promise in the rapid treatment of symptoms of major depression and suicidal thoughts, according to a new study published online today in The American Journal of Psychiatry (AJP).

The double-blind study compared the standard treatment plus an intranasal formulation of esketamine, part of the ketamine molecule, to standard treatment plus a placebo for rapid treatment of symptoms of major depression, including suicidality, among individuals at imminent suicide risk. The study involved 68 participants randomly assigned to one of two groups – either receiving esketamine or placebo twice a week for four weeks. All participants continued to receive treatment with antidepressants throughout. The researchers looked at effects at four hours after first treatment, at 24 hours and at 25 days.
