Augmentative treatment is considered the best second-option when a first-choice drug has partial limitations, particularly by allowing antidepressant dose reduction. Considering that ketamine has significant knock-on effects, this study investigated the effects of single coadministration with subthreshold doses of ketamine plus guanosine in a corticosterone (CORT)-induced animal model of...

The strategy of repeated ketamine in open-label and saline-control studies of treatment-resistant depression suggested greater antidepressant response beyond a single ketamine. However, consensus guideline stated the lack of evidence to support frequent ketamine administration. We compared the efficacy and safety of single vs. six repeated ketamine using midazolam as active placebo. Subjects...

Background The use of ketamine in electroconvulsive therapy (ECT) has been examined in the treatment of major depressive disorder (MDD); however, there has been no systematic review and meta-analysis of related randomised controlled trials (RCTs).Aim To examine the efficacy and safety of ketamine augmentation of ECT in MDD treatment.Methods Two reviewers searched Chinese (China National...

Accumulating evidence implicates dysregulation of hippocampal synaptic plasticity in the pathophysiology of depression. However, the effects of ketamine on synaptic plasticity and their contribution to its mechanism of action as an antidepressant, are still unclear. We investigated ketamine’s effects on in vivo dorsal hippocampal (dHPC) synaptic plasticity and their role in mediating aspects of...

There is a growing evidence for the rapid and robust antidepressive effect of ketamine in unipolar and bipolar treatment resistant depression although evidence for the risk of affective switch is still limited. This case presents bipolar I disorder patient with treatment resistant depressive episode experiencing a switch to manic episode with mixed features shortly after receiving eight...

Background Recent evidence underscores the utility of rapid-acting antidepressant interventions, such as ketamine, in alleviating symptoms of major depressive episodes (MDE). However, to date, there have been limited head-to-head comparisons of intravenous (IV) ketamine infusions with other antidepressant treatment strategies in large randomized trials. This study protocol describes an ongoing...

OBJECTIVE: Esketamine, the S-enantiomer of ketamine, was recently approved as a rapid-acting intranasal therapy for depression and is currently under development for suicidality. The authors sought to determine the efficacy of adjunctive intranasal esketamine in major depressive disorder (MDD). DATA SOURCES: A systematic search of PubMed/MEDLINE was conducted up to January 2019, in addition to...

N-methyl-d-aspartate receptor (NMDAR) antagonists, including ketamine and nitrous oxide, are currently intensely studied as rapid-acting antidepressant agents. Interestingly, both of these compounds are also drugs of abuse. Intravenous ketamine, a dissociative anesthetic that induces complex downstream effects via NMDARs, rapidly reduces depressive and suicidal symptoms in treatment-resistant...

OBJECTIVE: To compare esketamine to placebo, each in addition to standard-of-care treatment, for rapidly reducing major depressive disorder symptoms, including suicidal ideation. METHODS: This phase 3, double-blind, multicenter study (ASPIRE I), conducted between June 2017 and December 2018, enrolled 226 adults having major depressive disorder based on Diagnostic and Statistical Manual of...
