Emerging Clinical Applications of Ketamine and Esketamine Across Psychiatric Disorders.

Abstract

Over the past 25 years, the field of psychiatry has seen a rapid expansion of ketamine treatment services offered for the off-label management of depression, anxiety, and other psychiatric disorders as well as the U.S. Food and Drug Administration's approval of intranasal esketamine, the S-enantiomer of ketamine, for treatment-resistant depression and suicidal depression. In this review, the authors describe recent advances in the use of ketamine and esketamine for the treatment of depression and other psychiatric disorders, new research on novel treatment targets, and emerging evidence about ketamine's potential as a prophylactic intervention. Key outstanding issues and limitations of current ketamine treatment also are discussed.
