Depression is a common and serious psychiatric disorder with significant impacts on individuals. Modified electroconvulsive therapy (MECT) is an established treatment for severe and treatment-resistant depression, but its cognitive side effects, particularly memory impairments, limit its use. Esketamine (ESK), an FDA-approved antidepressant, has shown neuroprotective effects. However, its role...
The INTEGRATE study aimed to provide information on the use, effectiveness, and safety of esketamine nasal spray (ESK-NS) for the treatment of treatment-resistant depression (TRD) in real-world practice in Spain. This was an observational, cross-sectional, retrospective study conducted in adults aged 18-74 years who met the criteria for TRD. The weekly impact of ESK-NS on depressive symptoms...
Depression is a severe and recurrent neuropsychiatric disease with high prevalence, disability, and mortality, which imposes a heavy burden on national public health and the economy. Traditional antidepressants demonstrate delayed effects, low cure rates, and inadequate therapeutic effectiveness for managing treatment-resistant depression. Numerous studies have proved that esketamine, a...
Esketamine has shown promise in mitigating tissue damage caused by ischemia- reperfusion injury, making it a potential therapeutic candidate for acute lung injury (ALI) induced by limb ischemia-reperfusion (LIR-ALI). This study sought to explore the role and mechanism of esketamine in the LIR-ALI rat model. The effects of esketamine on the LIR-ALI rats model were evaluated through...
Oral esketamine for patients with treatment-resistant depression (TRD) could offer certain advantages over other routes, such as intravenous or intranasal, but it has not been systematically studied in a real-world setting. Here we present results from a relatively large naturalistic study to evaluate the effectiveness, tolerability, and safety of oral esketamine in patients with TRD. One...
Background: Esketamine is a rapidly acting antidepressant with robust efficacy in treatment-resistant depression (TRD). Diminishing therapeutic effects and attenuated side effects have been reported after long-term use. This study aimed to investigate its long-term pharmacokinetics and factors that may contribute to reduced efficacy over time in patients with TRD by evaluating the potential...
Background Postoperative depression (POD) represents a serious complication in surgical patients, exacerbating morbidity and mortality rates while imposing a substantial economic burden on healthcare systems. Despite its widespread clinical use, the role of esketamine, an NMDA receptor antagonist with rapid antidepressant effects, remains understudied in perioperative settings. Therefore, we...
Remimazolam is a novel benzodiazepine sedative that provides effective sedation, stable haemodynamics, and minimal adverse effects during intravenous general anaesthesia. The aim of this study was to determine the 50% effective dose (ED50) of remimazolam combined with different doses of esketamine for painless gastroscopy and to evaluate the efficacy and safety of this combination. This was a...
To investigate whether continuous intravenous infusion of esketamine during surgery can improve postoperative delirium (POD) and inflammatory response in patients undergoing off-pump coronary artery bypass grafting (OPCAB). Prospective, triple-blind, randomized controlled trial. A single tertiary center. 140 adult patients undergoing elective OPCAB. Patients in Group S (esketamine group)...
In this case report, we present a patient with treatment-resistant depression (TRD) and comorbid generalized anxiety disorder, eating disorder, post-traumatic stress disorder, and borderline personality disorder. Over a 10-year period, our case transitioned from adolescence to adulthood and received antidepressant monotherapy, adjunctive therapy with antipsychotics, lithium, or lamotrigine,...
