Key Points Question For inpatients with moderate to severe depression, is repeated intravenous ketamine superior to a psychoactive placebo (midazolam) in reducing depressive symptoms? Findings In this randomized clinical trial, there was no statistically significant difference in the primary outcome, end-of-treatment Montgomery-Åsberg Depression Rating Scale score, between the ketamine and...

This case report discusses a 62-year-old male with treatment-resistant bipolar II depression and hypertension. After poor responses to multiple treatments, an add-on esketamine nasal spray (ESK-NS) was introduced in October 2022. Improvement was seen, and the patient's depressive episode was nearly remitted during the maintenance phase. However, recurrence was noted when ESK-NS frequency was...

Ketamine is effective for treatment resistant depression (TRD); but cost-effectiveness evidence remains limited. To evaluate the cost-effectiveness of subcutaneous ketamine for TRD from health sector and societal perspectives. A cost-utility analysis alongside the KADS randomised controlled trial (RCT) involved 174 participants receiving ketamine or midazolam (active control) twice weekly for 4...

Clinical response and remission may not fully reflect patient priorities in treatment-resistant depression (TRD). Health-related quality-of-life (HRQoL) outcomes should be assessed to comprehensively capture treatment benefits. ESCAPE-TRD (NCT04338321) was a 32-week randomized, phase IIIb trial comparing esketamine nasal spray (NS) versus quetiapine extended release (XR), both alongside an...

A significant percentage of depression patients are resistant to pharmacological treatments, highlighting the need for novel antidepressant strategies. Ketamine, an NMDA receptor antagonist, produces rapid antidepressant effects and is effective in treatment-resistant cases, but its association with cognitive and behavioral abnormalities resembling schizophrenia limits broader clinical utility....

INTRODUCTION Treatment-resistant depression (TRD) represents a significant therapeutic challenge, as conventional treatments demonstrate limited efficacy. Although ketamine's acute antidepressant effects are well-documented, the role of maintenance therapy remains understudied. We conducted a systematic review to assess the efficacy, safety, and optimal implementation strategies of ketamine...

Treatment-resistant depression (TRD) represents a major clinical challenge. Affecting about 30 % of major depressive disorder (MDD) patients, effective treatments for TRD are urgently needed. While depression research and antidepressant (AD) development have long centred on monoaminergic targets, research over the past 35 years has increasingly explored glutamatergic mechanisms. Here we present...

Major depressive disorder (MDD) frequently co-occurs with substance use disorders (SUDs), leading to poorer outcomes and limited options. Esketamine is approved for treatment-resistant depression (TRD); its effects on craving and abstinence in SUD are less explored. A 41-year-old man with recurrent MDD (suicidal ideation) and polysubstance use (daily morphine/prescription opioids; intermittent...

Background: Ketamine, an N-methyl-D-aspartate antagonist, has been used for decades as an anesthetic agent, but more recently it has been studied in psychiatric illness. Though ketamine has been investigated for use in the general population, fewer studies have investigated the efficacy and tolerability of this treatment for older (age >60) adults. Objectives: This review sought to compile the...
