At least one third of patients with major depressive disorder do not experience adequate response to several rounds of antidepressant therapy, and a core 20% fail to respond to available antidepressants and evidence-based psychotherapies. Advanced neuromodulation approaches have been developed including repetitive transcranial magnetic stimulation and vagal nerve stimulation, but all have significant limitations. Ketamine, a dissociative anesthetic that has been available in the US since 1970, has been developed as a novel antidepressant for difficult to treat depression (DTD) and major depressive disorder with suicidal ideation (MDDSI) over the last 15 years. Following early studies by Drs. Robert Berman and colleagues at Yale University and Carlos Zarate and collaborators at the intramural program of the NIMH, evidence of the effectiveness of IV ketamine and, later, an intranasal form of the S(+)-enantiomer of ketamine called esketamine has steadily accumulated. This culminated in the approval of esketamine (SpravatoTM) for DTD in 2019 and MDDSI in 2020. Ketamine and esketamine have been among the most “rationally developed” medications in Psychiatry, in that they target one of the putative underlying pathophysiological mechanisms underlying depression, neuroplasticity. This presentation will review the clinical data in support of the effectiveness of ketamine and esketamine for DTD and MDDSI; the limitations, adverse effects, and controversies surrounding their use; their hypothesized mechanisms of action and how that relates to theoretical causal processes for depression. Participants should understand if and how they might use esketamine in their practice. They should also be able to describe the theoretical mechanisms, benefits and limitations of esketamine to their patients. This should help them make rational decisions about choosing among the available advanced treatment options for depression.
