Treatment-resistant depression (TRD) affects around 20-30% of people with major depressive disorder. In 2019, esketamine nasal spray was approved for TRD by both the US Food and Drug Administration and the European Medicines Agency. While its clinical efficacy and safety are proven, the mechanisms underlying its antidepressant effect remain unclear. The use of metabolomics may allow...
The antidepressant effects of ketamine and esketamine are well-documented. Nonetheless, most of the underlying molecular mechanisms have to be uncovered yet. In the last decade, metabolomics has emerged as a useful means to investigate the metabolic phenotype associated with depression as well as changes induced by antidepressant treatments. This mini-review aims at summarizing the main...
