Esketamine is a novel treatment for treatment resistant depression (TRD) and was approved by the FDA in early 2019. It antagonizes the NMDA receptor providing rapid improvement in symptoms with a complex mechanism of action primarily mediated through glutamatergic activation. Significant barriers exist to widespread use of esketamine including durability of response, particularly in the...

Alcohol use disorder (AUD) is especially prevalent among individuals with major depressive disorder (MDD) and is associated with higher morbidity, mortality, disability, and risk for suicide. Intranasal esketamine has been documented to be a safe and effective option for treatment resistant MDD and received US FDA approval in 2019. However, the availability of esketamine is limited due to...

Pharmacological magnetic resonance imaging (phMRI) is a noninvasive method used to evaluate neural circuitry involved in the behavioral effects of drugs like ketamine, independent of their specific biochemical mechanism. The study was designed to evaluate the immediate effect of esketamine, the S-isomer of (±) ketamine on brain activity in awake mice using blood oxygenation level dependent...

Ketamine has demonstrated rapid and significant antidepressant effects in patients with treatment resistant depression (TRD). Herein, we conducted a systematic review to determine ketamine's efficacy as a function of the stage of treatment resistance (e.g., number of failed treatments) among individuals with TRD. A systematic search of PubMed and Scopus from inception to August 2021 was...

Objective: To evaluate the efficacy and safety of esketamine + antidepressant in treatment-resistant depression. Methods: We searched PubMed, Web of Science, Embase, CNKI, and Wanfang databases to obtain published information on esketamine + antidepressant from inception to July 2022. We searched for randomized controlled studies on the treatment of depression with a double-blind induction...

To present the first real-world data of patients with treatment-resistant depression (TRD) treated with esketamine through a French cohort Temporary Authorisation for Use (ATUc) programme. In 2019, the French Health Authorities exceptionally granted the first ATUc in psychiatry for TRD patients. Clinical characteristics, safety and efficacy data were reported by physicians. The ATUc ended ∼6...

Over the past two decades, ketamine has emerged as a novel effective and safe rapid-acting antidepressant. While the vast majority of studies on ketamine have focused on its ability to reduce the severity of depression broadly, its effectiveness in specific domains such as cognition, anhedonia, suicidality, and workplace/social/scholastic functionality has been neglected. Similarly, current...

This article presents a mechanism of action hypothesis to explain the rapid antidepressant effects of esmethadone (REL-1017) and other uncompetitive N-methyl-D-aspartate receptor (NMDAR) antagonists and presents a corresponding mechanism of disease hypothesis for major depressive disorder (MDD). Esmethadone and other uncompetitive NMDAR antagonists may restore physiological neural plasticity in...

This publication discusses two compounds belonging to the psychoactive substances group which are studied in the context of depression treatment—psilocybin and esketamine. The former is a naturally occurring psychedelic. The latter was invented in the laboratory exactly 60 years ago. Although the substances were controversial in the past, recent studies indicate the potential of those...

OBJECTIVE The aim of this study was to estimate the cost-effectiveness of esketamine nasal spray relative to intravenous ketamine for patients with treatment-resistant depression (TRD) in the US. METHODS We used a Markov model with a 1-month cycle length, and we estimated quality-adjusted life years (QALYs), costs (2020 USD), and incremental cost-effectiveness ratios (ICER) of esketamine...
