Background Postpartum depression (PPD) is a common complication of cesarean section. S-ketamine given intravenously during surgery can help prevent PPD. However, whether S-ketamine in patient-controlled intravenous analgesia (PCIA) can reduce the incidence of PPD is unknown. This study assessed the effect of S-ketamine as an adjuvant in PCIA for preventing PPD in women undergoing cesarean...
Abstract Objective This work was undertaken to define and characterize the role of currently available somatic treatments in psychiatry in either increasing or reducing the risk for suicide. Methods Members of the Suicide Prevention Task Group of the National Network of Depression Centers performed a literature review of somatic treatments known to increase or reduce the risk for suicide. The...
Extending adjunctive treatment with esketamine nasal spray over 4 weeks showed benefit in a group of patients with treatment‐resistant depression who did not respond within the first week of treatment, a post hoc analysis of two Phase 3 studies has found. The results suggest that a full 4‐week induction of esketamine with an oral antidepressant may optimize treatment outcomes, the researchers...
Abstract Background Esketamine nasal spray (Spravato) in conjunction with oral antidepressants (ADs) is approved in the European Union, United States, and other markets for treatment-resistant depression (TRD). Efficacy, safety, and tolerability of esketamine nasal spray in Japanese patients with TRD needs to be assessed. Methods This Phase 2b, randomized, double-blind (DB), placebo-controlled...
To summarize the evidence of efficacy and safety of the use of ketamine and esketamine for depression. A literature search was performed in Medline, the Cochrane Library, LILACS, and CRD until November 2020. We included systematic reviews with meta-analyses of randomized controlled trials on the use of ketamine and esketamine in adult patients with depression. Two authors independently...
Intranasal form of esketamine, the S-enantiomer of racemic ketamine, was approved by the US FDA in 2019 for treatment-resistant depression (TRD) in adults. Since intranasal esketamine is a newly approved drug with a novel mechanism of action, much still remains unknown in regard to its use in TRD. The objective of this study is to systematically review the latest existing evidence on intranasal...
Comorbid anxiety is generally associated with poorer response to antidepressant treatment. This post hoc analysis explored the efficacy of esketamine plus an antidepressant in patients with treatment‐resistant depression (TRD) with or without comorbid anxiety.
(Es)ketamine and monoamine oxidase inhibitors (MAOIs), e.g., tranylcypromine, are therapeutic options for treatment-resistant major depression. Simultaneous administration is currently not recommended because of concern about hypertensive crises. Our objective was to evaluate whether changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) during esketamine...
) and treatment-resistant depression (TRD) who did not meet response criteria within the first week of treatment. The current study is a pooled post hoc analysis of two phase 3, double-blind, active-controlled studies, conducted between August 2015 and February 2018, comparing ESK + AD with an oral antidepressant plus placebo (AD + PBO). Early treatment response was defined as a ≥ 50% decrease...
Abstract Over the past few years, intranasal esketamine has been FDA-approved for treatment-resistant depression as well as MDD with suicidal ideation. In the clinical trials leading to the recent FDA approvals, subjects with a diagnosis of bipolar disorder were excluded from participation in the trial. The manufacturer of intranasal esketamine states that it “has not been studied, and is not...
The obsessive-compulsive spectrum refers to disorders drawn from several diagnostic categories that share core features related to obsessive-compulsive disorder (OCD), such as obsessive thoughts, compulsive behaviors and anxiety. Disorders that include these features can be grouped according to the focus of the symptoms, e.g., bodily preoccupation (i.e., eating disorders, ED) or impulse control...
Abstract Introduction: Invariably, the search for an “ideal drug” in psychiatry has been going for years, one that is safe and effective, prevents relapse and shows the least possible side effects. Material and methods: The aim of this study authors is to draw attention to new drugs used in psychiatry- cariprazine, lurazidone and esketamine, their mechanism of action, dosage, the most common...
Esketamine appears more likely than venlafaxine to cause suicidal ideation. Induction of mania was more common than with venlafaxine. Induction of euphoric mood suggests abuse potential. Caution is warranted.
Dissociative symptoms are common, possibly severe, side effects associated with the use of ketamine and esketamine in depression. We investigated the relationship between trait dissociation and dissociation induced by ketamine and esketamine used as augmentation therapy in treatment-resistant depression (TRD). Adults with TRD were randomly assigned to receive a single intravenous infusion, with...

Introduction Esketamine had been rised as a potential treatment for Resistant Depression, becoming an alternative for the use of Electroconvulsive Therapy. In Spain since 2020, it has been applied for compassionate use but is not widely used. Although Esketamine is defined safe and effective in preliminary studies, there are common side effects which could reduce it use. Objectives Increasing...
Replicated international studies have underscored the human and societal costs associated with major depressive disorder. Despite the proven efficacy of monoamine-based antidepressants in major depression, the majority of treated individuals fail to achieve full syndromal and functional recovery with the index and subsequent pharmacological treatments. Ketamine and esketamine represent...
Major depressive disorder affects an estimate of 5% of the population with nearly 1‑third of patients failing to achieve remission with conventional pharmacological treatment. Esketamine, a novel rapid‑acting antidepressant, with a noncompetitive antagonism on N‑methyl‑D‑Aspartate receptor, have been recently approved by Food and Drug Administration (FDA) and European Medicines Agency (EMA) for...
Ketamine and its (S)-enantiomer show distinct psychological effects that are investigated in psychiatric research. Its antidepressant activity may depend on the extent and quality of these psychological effects which may greatly differ between the enantiomers. Previous data indicate that the (S)-ketamine isomer is a more potent anesthetic than (R)-ketamine. In contrast, in subanesthetic doses...
This column reviews the development of intranasal esketamine with particular emphasis on the consistency of the clinical trial results. In the process, it illustrates methodological issues important in the approval process by an agency such as the United States Food and Drug Administration. Topics covered include the importance of study design, the nature of the comparator, and the prespecified...
Patients with treatment-resistant depression (TRD) treated with esketamine nasal spray commonly experience transient symptoms of dissociation. Manifestations of dissociation, such as feelings of detachment from the environment, can cause considerable anxiety for patients. Nonpharmacologic interventions may help clinicians to manage associated anxiety and confusion due to dissociation following...
