> The full article, *Efficacy and Safety of Intranasal Esketamine for the Rapid Reduction of Symptoms of Depression and Suicidality in Patients at Imminent Risk for Suicide: Results of a Double-Blind, Randomized, Placebo-Controlled Study* can be found [here](

I’ll be excited to see the final results! We definitely need more tools in our psychiatric arsenal and this is probably the best test of the ketamine hypothesis (the idea that it is something of a wunder-drug for mental disorders).
