Despite affecting millions worldwide, major depressive disorder (MDD) remains a therapeutic challenge, with approximately one-third of patients failing to respond to standard treatments. The need for innovative, molecularly driven therapies has turned attention to ketamine and its enantiomers. While S-ketamine is clinically approved for treatment-resistant depression (TRD), it has various...

Ketamine and esketamine (ESK) offer new treatment options for resistant depression. Unlike traditional antidepressants, they can be used in combination with non-selective monoamine oxidase inhibitors (NS-MAOI) without the risk of serotonergic syndrome. However, potential sympathomimetic synergy may lead to elevated blood pressure (BP). This series investigates whether cardiovascular parameters...
Results of a systematic review and meta‐analysis suggest that esketamine has only modest efficacy in the treatment of adults with treatment‐resistant depression, with initial improvement diminishing after the first few days. The results also suggest no effect of esketamine on suicidality.
Despite being approved by the US FDA and the EU European Medicines Agency, the performance of esketamine nasal spray as an adjunctive therapy with an antidepressant in major depressive disorder is still controversial. Comprehensive retrieval in Embase, Pubmed, and Web of Science was conducted to identify randomized controlled trials comparing esketamine nasal spray versus control in major...
Assessment measures for suicidal behavior range from depression scales to longer suicide-specific instruments. In this review, we systematically summarize and discuss the currently used instruments for assessing suicidal behavior in the context of ketamine and its enantiomers. We searched Medline/PubMed, Embase, and PsycINFO databases for ketamine (and its enantiomers) human studies exploring...

Ketamine and esketamine are increasingly used to manage treatment-resistant depression and have also been shown to reduce symptoms of posttraumatic stress disorder (PTSD). Little is known about how common comorbidities in the veteran population, such as traumatic brain injury (TBI) or obstructive sleep apnea (OSA), may influence ketamine and esketamine treatment outcomes. In this retrospective...
Abstract Objective Ketamine and esketamine have both shown significant antidepressant effects in treatment-resistant depression (TRD) and conflicting evidence suggests that dissociation induced by these drugs could be a clinical predictor of esketamine/ketamine's efficacy. Methods This study is a secondary analysis of data from a two-center, randomized, controlled trial. Participants were...

Prenatal stress leads to postpartum depression and is associated with developmental issues in offspring. Esketamine quickly and effectively prevents or treats postpartum depression. However, the long-term effects of esketamine on progeny development are unknown. CRS during pregnancy was used to establish the postpartum depression animal model. After confirming pregnancy, all mice were randomly...
Background/Objective: Major depressive disorder (MDD) is a common mental disorder, with a significant portion of patients developing treatment-resistant depression (TRD). Esketamine is an antagonist of the N-methyl-D-aspartate receptor indicated as a nasal spray in combination with other antidepressants for adults with TRD. Signals of suspected adverse reactions (SARs) to esketamine from the...
Pharmacological management of major depressive disorder has traditionally relied on antidepressants targeting the monoaminergic pathway. Treatment-resistant depression (TRD) patients have been frequently excluded from registrational trials, resulting in a lack of clear clinical recommendations for an optimised management. In recent years, treatments based on other mechanisms of action have been...
