Ketamine and esketamine have garnered interest in both psychiatric research and clinical practice for treatment-resistant depression (TRD). In this review, we examined registered trials investigating the therapeutic use of ketamine or esketamine for TRD, with the aim of characterizing emerging trends and knowledge gaps.The ClinicalTrials.gov electronic registry and results database was queried...

BACKGROUND: Bipolar depression accounts for most of the disease duration in type I and type II bipolar disorder (BD), with few treatment options, often poorly tolerated. Many individuals do not respond to first-line therapeutic options, resulting in treatment-resistant bipolar depression (B-TRD). Esketamine, the S-enantiomer of ketamine, has recently been approved for treatment-resistant...

Antidepressants require several weeks for the onset of action, a lag time that may exceed life expectancy in palliative care. Ketamine has demonstrated rapid antidepressant effects, but has been minimally studied in cancer and palliative care populations. Herein, the objective was to determine the feasibility, safety, tolerability and preliminary efficacy of intranasal racemic ketamine for...

OBJECTIVE To evaluate the effects of ketamine treatment on depression and suicidal ideation in treatment resistant depression (TRD) and to determine whether they are influenced by other psychiatric and personality comorbidities. METHODS A randomized double-blind parallel-arm controlled study on 36 patients with TRD. Patients were divided into two treatment groups: ketamine (K group) and placebo...

OBJECTIVE Hippocampal functional connectivity (FC) alterations, which may happen following ketamine treatment, play a key role in major depression remission. This study aims to investigate the resting-state FC changes of the hippocampus associated with clinical remission after repeated ketamine infusions. METHODS Forty-four major depressive patients received six intravenous ketamine (0.5 mg/kg)...

The glutamatergic system is the primary excitatory pathway within the CNS and is responsible for cognition, memory, learning, emotion, and mood. Because of its significant importance in widespread nervous system function, it is tightly regulated through multiple mechanisms, such as glutamate recycling, microglial interactions, and inflammatory pathways. Imbalance within the glutamatergic system...

Thirty percent of depressed patients are treatment resistant (TRD) suggesting the need of new therapeutic strategy. Recently, it has been shown that ketamine, an anesthetic agent with dissociative effects, has potent and rapid antidepressant properties. Ketamine is a ionotropic glutamatergic NMDA antagonist that inhibits gabaergic neurons. Its antidepressant effect peaks at 24 h post-treatment....
