Abstract Background At ketamine and esketamine doses at which antidepressant doses are achieved, these agents are relatively selective, noncompetitive, N-methyl-D-aspartate receptor antagonists. However, at substantially higher doses, ketamine has shown mu-opioid receptor (MOR–gene symbol: OPRM1) agonist effects. Preliminary clinical studies showed conflicting results on whether naltrexone, a...

OBJECTIVE: To evaluate long-term safety and efficacy of esketamine nasal spray plus a new oral antidepressant (OAD) in patients with treatment-resistant depression (TRD). METHODS: This phase 3, open-label, multicenter, long-term (up to 1 year) study was conducted between October 2015 and October 2017. Patients (≥ 18 years) with TRD (DSM-5 diagnosis of major depressive disorder and nonresponse...

BACKGROUND: Esketamine nasal spray was recently approved for treatment-resistant depression. The current analysis evaluated the impact of symptom-based treatment frequency changes during esketamine treatment on clinical outcomes. METHODS: This is a post-hoc analysis of an open-label, long-term (up to 1 year) study of esketamine in patients with treatment-resistant depression (SUSTAIN 2). During...

Abstract: Background: Targeting of glutamate receptors is a novel approach for the treatment of major depressive disorder (MDD). This study aimed to review the usefulness for esketamine nasal spray for the management of treatment-resistant depression (TRD) using the tools of evidence-based medicine: number needed to treat (NNT), number needed to harm (NNH), and likelihood to be helped or harmed...

Elderly patients with treatment‐resistant depression did not see overall improvement in depression symptoms over 28 days with use of esketamine nasal spray plus an oral antidepressant, a placebo‐controlled Phase 3 study has found. A younger subgroup of the overall study sample, as well as patients with earlier onset of depression, showed some improvement with esketamine, the researchers...

Since the discovery of its rapid-acting antidepressant properties, ketamine has helped stimulate a new line of research in the development of rapid-acting antidepressants based on the glutamate and gamma-aminobutyric acid neurotransmitter systems. An intranasal version of the S-enantiomer of ketamine (esketamine) recently received regulatory approval as a therapy for treatment-resistant...

BACKGROUND: A research on mood disorder pathophysiology has hypothesized abnormalities in glutamatergic neurotransmission, by suggesting further investigation on glutamatergic N-methyl-Daspartate (NMDA) receptor modulators in treating Major Depressive Disorder (MDD). Esketamine (ESK), an NMDA receptor antagonist able to modulate glutamatergic neurotransmission has been recently developed as an...

Abstract In March 2019, the US Food and Drug Administration (FDA) approved a nasal spray formulation of esketamine for the treatment of resistant depression in adults. Esketamine is the S-enantiomer of ketamine, an FDA-approved anaesthetic, known to cause dissociation and, occasionally, hallucinations. While ketamine has not been approved for depression in the USA or in any other country, it...
