Little is known about esketamine's effectiveness for patients with major depressive disorder (MDD) comorbid substance use disorders (SUD). We conducted a retrospective cohort study using the TriNetX US Collaborative Network, including adults aged ≥18 years with MDD. Three propensity-score-matched (1:1) cohorts were defined based on treatment: esketamine, antidepressant-only, and repetitive...

Repetitive transcranial magnetic stimulation (rTMS) and intranasal esketamine are FDA-approved for treatment-resistant depression (TRD), yet comparative real-world data on response trajectories and predictors of outcomes remain limited. A retrospective analysis was performed using electronic medical records from UC San Diego Health. Adults with TRD treated with rTMS (n = 279) or intranasal...

To compare the efficacy and safety of electroconvulsive therapy (ECT) and ketamine infusion (KET-IFU) in routine care for patients with bipolar I or II depression (BPD). Electronic medical records of patients who received ECT and/or KET-IFU were used to identify patients with BPD who received both ECT and KET-IFU treatments. The change in the 16-item Quick Inventory of Depressive Symptomatology...

Ketamine and esketamine ("es/ketamine") treatment protocols have been investigated in patients' samples with treatment-refractory anxiety disorders. We systematically reviewed publications in which es/ketamine was used to treat anxiety symptoms in the context of either Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) anxiety disorders or treatment-resistant...

Introduction Treatment-resistant depression (TRD), which affects about 30% of patients with major depressive disorder, emerges when patients do not respond adequately to at least two antidepressant trials of proper dose and duration. The EMA approved esketamine nasal spray, the first registered psychedelic medication, in 2019 for TRD treatment. In July 2023, Poland launched B.147, the country’s...

Introduction Treatment-resistant depression (TRD) poses a significant clinical challenge, with limited evidence guiding long-term pharmacological strategies. Esketamine, a glutamatergic modulator, has demonstrated short-term efficacy in TRD, but data on its extended use in real-world settings remains scarce Objectives This study aimed to evaluate the long-term effectiveness and tolerability of...

Introduction Hopes related to esketamine have been raised by its approval for treatment-resistant major depression (TRD) in the sense that this antidepressant, with a novel mechanism of action, will be useful for patients with bipolar depression (BD), too. The need to find more evidence-based pharmacological approaches to both TRD and BD is acute due to the high rates of partial response or...

Introduction Adult attention-deficit/hyperactivity disorder (ADHD) frequently co-occurs with mood and anxiety disorders (Sandstrom et al. Acta Psychiatr Scand 2021;143 380–391), and when major depressive disorder (MDD) is present, it often follows a treatment-resistant course (Thapar et al. J Child Psychol Psychiatry 2023;64 4–15). Intranasal esketamine, a non-competitive NMDA-receptor...

Introduction Suicidality represents a major clinical and public health challenge, particularly among patients with treatment-resistant depression (TRD), who carry a disproportionately high risk of suicide. Traditional antidepressants often have delayed onset and limited efficacy in reducing suicidal ideation in this high-risk population, highlighting the need for rapid-acting interventions....

A two‐year extension of a trial of esketamine nasal spray in patients with treatment‐resistant depression has found no new safety concerns associated with long‐term use of the drug. The overall relapse rate across both the original trial and the extension was 6.9%.
