Bolus versus Continuous Infusion of Esketamine for Prevention of Postpartum Depression After Caesarean Delivery: A Randomized, Double-Blind, Controlled Trial.

Drug Design, Development and Therapy 2026 Jie Yang, Qiqi Yan, Ting Zhang et al.

Esketamine is increasingly being applied for preventing postpartum depression (PPD). However, clinical protocols for this application are inconsistent, particularly concerning the route of administration. The aim was to determine whether esketamine bolus administration differed from continuous infusion in terms of preventing PPD. A total of 503 subjects without prenatal depression undergoing...

Mental health professionals' perspective on the use of esketamine in treatment-resistant depression and their motivation to adopt it: a Saudi cross-sectional study.

Frontiers in Psychiatry 2026 Ahmad H Almadani, Ayedh H Alghamdi, Gosay M Almazyad et al.

Esketamine is an innovative treatment for individuals with treatment-resistant depression (TRD). However, its adoption could depend on the perceptions and motivations of prescribing psychiatrists, among other factors. This study aims to explore the attitudes of psychiatrists (of all levels, including those in training) across Saudi Arabia toward the use of esketamine for TRD and investigate the...

Single low-dose esketamine improves postpartum depression symptoms and recovery quality in cesarean section women.

American Journal of Translational Research 2026 Ran Jing, Yuanyan Tu

To investigate the effects of single low-dose esketamine combined with patient-controlled intravenous analgesia (PCIA) on early postpartum depression symptoms and recovery quality in women undergoing cesarean section. This prospective, randomized, controlled study enrolled 136 women scheduled for elective cesarean section, who were randomly assigned in a 1:1 ratio to the study group (esketamine...

Esketamine ameliorates depression-like behavior in mice via modulation of the NRG1-ErbB4 pathway.

Frontiers in Psychiatry 2026 Hang Yu, Yuqiong Zhu, Jie Wang et al.

Esketamine has a significant and rapid antidepressant effect. Although studies have shown that Neuregulin 1 (NRG1) and it's signaling pathway are associated with depression, the possible regulatory relationship of esketamine on the NRG1-ErbB4 pathway is not yet clear. To induce depressive-like behavior in mice, a Chronic Social Defeat Stress (CSDS) model was established. Behavioral indicators...

Intranasal esketamine in treatment-resistant depression: long-term dosing patterns and clinical outcomes in a 5-year observational study.

Therapeutic Advances in Psychopharmacology 2026 Alessandro Cuomo, Roger S McIntyre, Despoina Koukouna et al. 1 citation

Treatment-resistant depression (TRD) remains a major clinical challenge, and long-term real-world data on intranasal esketamine are limited. To describe long-term dosing patterns and clinical outcomes associated with intranasal esketamine in routine clinical practice. Single-center observational cohort study with descriptive analyses. We analyzed 45 patients with TRD treated with intranasal...

Rapid reduction of suicidal ideation with transient dissociative and "drunken gait" symptoms after intranasal esketamine, with music intervention: a case report.

Frontiers in Psychiatry 2026 Haihua Tian, Zongfeng Zhang, Yan He et al. 1 citation

Treatment-resistant depression (TRD) is often accompanied by persistent suicidal ideation and poor response to conventional antidepressants. Intranasal esketamine, a non-selective NMDA receptor antagonist, provides rapid antidepressant and anti-suicidal effects; transient dissociation is common, whereas ataxia-like "drunken gait" is rarely described. A 19-year-old woman with recurrent...

Pilot study on esketamine response in treatment-resistant depression: impact of pharmacogenetic, clinical, and demographic variables.

Frontiers in Pharmacology 2026 Michaela Krivosova, Matteo Marcatili, Gessica Guerrera et al.

Esketamine, the S-enantiomer of ketamine, is a rapid-acting antidepressant approved for treatment-resistant depression (TRD) when used in combination with an oral antidepressant. Identifying reliable clinical or genetic predictors of treatment response remains a critical unmet need. This study aimed to evaluate the impact of selected clinical and genetic variables on esketamine response in a...

Dose-dependent adverse events of esketamine in treatment-resistant depression: a systematic review and meta-analysis of randomized controlled trials.

Frontiers in Pharmacology 2026 Yang Qu, Shujin Li, Li Tian et al.

This study systematically evaluated the safety profile of esketamine for treatment-resistant depression through a meta-analysis, focusing on dose-dependent adverse events and associated risk factors to inform precision dosing.

Patient-centred education for ketamine and esketamine therapies in mood disorders.

Therapeutic Advances in Psychopharmacology 2026 Zofia Kachlik, Wiesław Jerzy Cubała, Michał Walaszek

Treatment-resistant depression (TRD) and bipolar depression (TRBD) are severe, heterogeneous mood disorders associated with substantial functional impairment, elevated suicide risk and persistent unmet treatment needs. While pharmacological and psychological interventions continue to advance, many patients experience delayed, partial or unsustained benefit, underscoring the need for therapies...

Is the antidepressant efficacy of ketamine and esketamine mediated via opioid mechanisms?

European Psychiatry 2026 Andy Lu, Heidi Xu, Gia Han Le et al. 4 citations

The reported mixed findings suggest that the opioid system may exert a partial mediating effect of ketamine in TRD. However, given the inconsistent attenuation of ketamine's antidepressant effects by opioid receptor antagonists, the opioid system likely functions as a context-dependent modulator rather than a primary mediator, particularly at standard antidepressant doses.
