Mining and updating the post-marketing safety signals of esketamine nasal spray for better identification of adverse drug event (ADE) signals and medication monitoring during clinical use to ensure patient medication safety. Downloading data from the US Food and Drug Administration Adverse Event Reporting System from Q1 2019 to Q2 2023, the reporting odds ratio, proportional reporting ratio,...
Moderate-to-severe acute postsurgical pain (APSP) can prolong the recovery and worsen the prognosis of patients who undergo spinal surgery. Esketamine and pregabalin may resolve APSP without causing hyperpathia or respiratory depression after surgery. However, there are other risks, such as dissociative symptoms. We designed a randomized controlled trial to investigate the effect of the...
About one-third of patients with depression do not achieve adequate response to current treatment options. Although intravenous and intranasal administrations of (es)ketamine have shown antidepressant properties, their accessibility and scalability are limited. We investigated the efficacy, safety, and tolerability of generic oral esketamine in patients with treatment-resistant depression (TRD)...
Ketamine and esketamine have been proven to be effective in treating adults with treatment resistant depression (TRD). Preliminary evidence indicates that, when combined with behavioral and psychological interventions, both agents may offer benefits for individuals with substance use disorder (SUD) and alcohol use disorder (AUD). Notwithstanding, concerns have been raised as to whether either...
Ketamine, an N-methyl-D-aspartate receptor antagonist, is a racemic mixture of esketamine and arketamine used to treat unipolar and bipolar depression. Preliminary reports indicate that it may be beneficial for depressed patients reporting symptoms of anhedonia. In this systematic review we aim to assess and analyze the existing body of evidence regarding the therapeutic effects of ketamine on...
The authors sought to assess the prosocial, entactogen effects of ketamine. Pleasure from social situations was assessed in a sample of participants with treatment-resistant depression from randomized, double-blind, placebo-controlled studies, using four items of the Snaith-Hamilton Pleasure Scale (SHAPS) at five time points over 1 week following treatment with ketamine (0.5 mg/kg...
In the United States (US), prescription drug coverage is subject to prior authorization (PA) criteria, which may vary between health plans and may exceed drug label requirements. This study aimed to characterize profiles and treatment history of patients with treatment-resistant depression (TRD) who initiated esketamine nasal spray, by stringency of their health plans' PA criteria relative to...
Catatonia, documented since the 19th century, remains a significant challenge in terms of recognition and treatment. Over the last two decades, ketamine has brought new perspectives to psychiatry, sparking widespread interest. Concurrently, catatonia has attracted heightened scientific attention. Preliminary evidence suggests the therapeutic potential of ketamine for catatonia. We...

Esketamine, the s(+) enantiomer of ketamine, was approved in 2019 as the first rapid-acting intranasal spray medication for treatment-resistant depression; the drug is given in combination with an antidepressant. The treatment is self-administered in a clinical setting under the supervision of a healthcare provider and usually is well tolerated. Many of its adverse reactions are mild,...

This study assesses the early effectiveness of esketamine nasal spray (ESK) in adults with treatment-resistant depression (TRD) 1 day after the first administration, as monitored through self-assessment via the mobile application, Esketamine Continuing Assessment for Relapse Prevention (EsCARe). In this multi-center, open-label, single-arm study, adults aged 18-65 years diagnosed with TRD after...
Introduction Esketamine intranasal spray has been approved in both the USA and EU as a novel treatment in patients with treatment-resistant major depression (TRD) and for the management of acute depressive emergencies during the course of major depressive disorder (MDD). Real-world data on the effectiveness and safety of esketamine nasal spray in clinical use are limited. Objectives To...

Introduction Major depressive disorder is a common psychiatric condition affecting around 264 million people worldwide (WHO: Depression Fact Sheet. [Apr;2021]). Despite pharmacological advances, many patients still do not respond to antidepressant treatment or do so partially. It is estimated that only 50-70% of patients respond to the initial antidepressant treatment according to the STAR-D...
The development of postpartum depression has been linked to fluctuations in the levels of neurotransmitters in the human body, such as 5-hydroxytryptamine (5-HT), dopamine (DA), noradrenaline (Norepinephrine, NE), and brain derived neurotrophic factor (BDNF). Research has indicated that the antidepressant effect of esketamine are mediated by monoamine transmitters and neurotrophic factors....
Background: Esketamine has received approval as a nasal spray (ESK-NS) for treatment-resistant depression (TRD) and evidence from real-world investigations has confirmed the effectiveness of ESK-NS, albeit with interindividual differences in response. Heart rate variability (HRV), defined as the fluctuation in time interval between consecutive heartbeats, can be used to measure autonomic...
Women with prenatal depressive symptoms who received a single low dose of esketamine shortly after childbirth showed a substantially lower incidence of a major depressive episode at 42 days postpartum than women receiving placebo, a new study has found. Neuropsychiatric adverse events occurred more frequently in the esketamine group, but no severe adverse events were reported.
Esketamine may reduce acute postoperative pain in several settings. However, the effects of low-dose esketamine on postoperative pain after vestibular schwannoma (VS) resection with propofol/remifentanil total intravenous anaesthesia (TIVA) are unclear. The aim of this study is to observe the effects of intraoperative low-dose esketamine on postoperative pain after vestibular schwannoma...
Therapeutics for suicide management is limited, taking weeks to work. This open-label clinical trial with 18 treatment-resistant depressive patients tested subcutaneous esketamine (8 weekly sessions) for suicidality. We noted a rapid and enduring effect of subcutaneous esketamine, lasting from one week to six months post-treatment, assessed by the Beck Inventory for Suicidality (BSI). There was...
In ESCAPE-TRD (NCT04338321), esketamine nasal spray (NS) significantly increased the probability of remission at Week 8, and of being relapse-free through Week 32 after remission at Week 8, versus quetiapine extended release (XR) in patients with treatment resistant depression (TRD). Here, we explore the time course, burden and consequences of treatment emergent adverse events (TEAEs) in the...
Recent decades have witnessed an extraordinary global crisis of drug misuse. Although opioid analgesics receive the most attention, numerous other drugs have increased rates of misuse. Ketamine and esketamine offer a unique natural experiment to explore two medications that are similar pharmacologically but differ in their availability to users and in their regulation by government agencies....
New daily persistent headache (NDPH) is a kind of persistent headache that patients can identify the exact date of the sudden onset.It is one of the rare primary headaches difficult to be cured and may lead to disability,seriously affecting the daily life and work.The exact pathogenesis of NDPH remains unclear,which makes the treatment difficult.Here we report a case of refractory NDPH treated...
