Antidepressant efficacy of ketamine in treatment-resistant major depression: a two-site randomized controlled trial
The authors evaluated the rapid antidepressant efficacy of ketamine in a large group of patients with treatment-resistant major depression. Ketamine demonstrated rapid antidepressant effects in an optimized study design, further supporting NMDA receptor modulation as a novel mechanism for accelerated improvement in severe and chronic forms of depression.
