Nasal esketamine has demonstrated efficacy in the management of treatment-resistant depression and psychiatric emergency due to major depression. This study investigates acceptance and awareness of esketamine as a depression treatment option, focusing on factors that influence patients' acceptance, including adherence to current medication regimens, regardless of prior esketamine exposure. This...
Ketamine and esketamine have demonstrated rapid, short-term antidepressant effects in major depressive disorder (MDD), but their relative safety remains unclear. This review aims to update the evidence on the safety of two agents for MDD and indirectly compare their safety and tolerability. We systematically searched PubMed, PsycINFO, Embase, and Cochrane databases up to 1 May 2025. Eligible...
Ketamine's antidepressant effects have been linked to its modulation of glutamatergic neurotransmission and synaptic plasticity. However, the precise roles of both glutamate (Glu) levels and brain-derived neurotrophic factor (BDNF) in this process remain incompletely understood. This study examined the relationship between ketamine-induced changes in Glu levels and peripheral BDNF levels using...
Depression affects approximately 5.7% of adults worldwide, and around one-third of these individuals develop treatment-resistant depression (TRD). Intravenous (IV) ketamine and esketamine (administered IV or intranasally (IN)) are novel treatment options for TRD; however, only IN esketamine currently holds FDA approval. Compare the acute effectiveness of IV ketamine with esketamine (IV or IN)...
To investigate the efficacy of intranasal esketamine in reducing the incidence of emergence agitation (EA) in pediatric patients undergoing adenotonsillectomy and to determine the optimal dose of esketamine. A total of 204 children aged 3-6 years scheduled for adenotonsillectomy were randomly assigned to three groups. All participants received a standardized anesthetic induction protocol....

The optimal and safest hypnotic agent for rapid sequence intubation in critically ill patients remains uncertain. Factors such as hypovolemia, vasoplegia, hypoxemia, and acidosis can influence the efficacy and safety of induction agents. Propofol is commonly used for this purpose; however, it is associated with the risk of exacerbating hypotension. Ketamine, which has a more favorable...
Intravenous ketamine is effective in treatment-resistant bipolar depression (TRBD) with dosing typically based on actual body weight (ABW). This study examined whether alternative normalization formulas are associated with treatment response. A retrospective exploratory analysis of a naturalistic registry for short-term ketamine use. A total of 22 TRBD inpatients received short-term intravenous...
Postoperative sleep disturbance (PSD) is a common complication following surgery. Numerous factors can contribute to PSD, including personal factors, intraoperative factors, postoperative complications and environmental factors. PSD can lead to a range of adverse outcomes, severely impairing patients' postoperative recovery and long-term prognosis. Esketamine, a non-competitive...
The primary outcome was the management of acute agitation, as measured by the Richmond Agitation-Sedation Scale (RASS). Secondary outcomes included the incidence of adverse effects and the time to onset of the therapeutic effect. This randomized clinical trial was conducted between March 2021 and March 2022. Participants were recruited from patients presenting with acute agitation who required...
Catatonia is a rare but potentially life-threatening psycho-motor syndrome. It is mainly manifested as decreased activities, or excessive and specific activities, such as stupor, agitation and defiance. Catatonia can appear in various diseases and the diagnosis and treatment of depressive catatonia are often delayed. As an N-methyl-D-aspartate (NMDA) receptor antagonist, esketamine shows...

Patients with schizophrenia frequently experience inadequate attribution of motivational salience, possibly related to impaired attentional processing and dysfunctional reward learning. According to the "glutamate hypothesis of schizophrenia", glutamatergic dysregulations can contribute to the emergence of psychotic symptoms and cognitive deficits in patients with schizophrenia. Blocking the...
Although Dexmedetomidine (DEX) can induce sleep that resembles natural sleep, it has demonstrated limited efficacy in patients with comorbid insomnia and depression. On the other hand, Esketamine (ESK) has shown a potent antidepressant effect. Herein, we aimed to establish whether esketamine could enhance the therapeutic efficacy of DEX in treating patients with comorbid insomnia and...
Intranasal (IN) esketamine has become an effective and well-tolerated therapeutic option for the management of treatment-resistant depression within major depressive disorder (MDD-TRD). Despite these promising benefits, given the prevalence of ketamine abuse, concerns remain over the addiction liability that may be associated with esketamine treatment. The objective of this study is to assess...
Major depressive disorder (MDD) has a high incidence and high risk of suicide. Electroconvulsive therapy (ECT) is a highly effective and rapid physical therapy for MDD but limited by adverse effects. Ketamine/esketamine are new emerging rapid antidepressants, which can synergize the efficacy and safety of ECT but come with other side effects. Binaural beat music (BBM) is a non-invasive...
Enhancing the early diagnosis and standardized treatment of major depressive disorder (MDD), as advocated by the National Health Commission of China, is a key priority in the mental health initiatives of the nation. To achieve this, numerous evidence-based rapid treatment centers for MDD have been established or are currently under development across the country. These centers focus on the...
The presence of fentanyl in the drug supply is thought to contribute to the incidence of buprenorphine-precipitated opioid withdrawal (BPOW) during initiation. Long used as a surgical anesthetic and an analgesic, the utility of ketamine for psychiatric and substance use disorder indications continues to grow. We present a case of intravenous (IV) ketamine use on the general medical floor for...
Ketamir-2 is a new molecular entity, and a novel ketamine analog designed to improve oral bioavailability, and offer a superior safety profile compared to existing ketamine treatments. It was found that Ketamir-2 is a low affinity NMDA receptor antagonist, that selectively binds to the PCP site. Its IC50 on this receptor site is ∼100 µM. Ketamine acts as an NMDA receptor antagonist (0.5-1 µM...
Patients suffering from depression frequently encounter extended periods of low moods and lack of enjoyment or enthusiasm for activities. It leads to suicidal thoughts and presents a potential hazard to their safety. Nowadays, there has been significant progress in researching the effectiveness and safety of esketamine in treating depression. Hence, this paper employs bibliometric analysis to...
Post-Traumatic Stress Disorder (PTSD) is a severe psychiatric condition that develops after exposure to trauma such as combat, natural disasters, or assault. It is characterized by re-experiencing trauma, avoidance, hyperarousal, and negative alterations in cognition and mood. Since its formal inclusion in the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III in 1980, PTSD has...
Mood disorders, anxiety, and suicidality in youth are increasing and rapid-acting treatments are urgently needed. One potential is ketamine or its enantiomer esketamine, which was FDA approved in 2019 to treat major depressive disorder with suicidality in adults. This systematic review evaluated the evidence for the clinical use of ketamine to treat mood disorders, anxiety, and suicidality in...
