Estimating the benefit of esketamine nasal spray versus real-world treatment on patient-reported functional remission: results from the ICEBERG study.

Frontiers in Psychiatry 2024 Albino J Oliveira-Maia, Benoit Rive, Yordan Godinov et al. 3 citations

Treatment resistant depression (TRD) affects approximately 10-30% of patients with major depressive disorder, and most patients with TRD do not respond to real-world treatments (RWT). Treatment with esketamine nasal spray (NS) plus a selective serotonin or serotonin norepinephrine reuptake inhibitor (SSRI/SNRI) has significant long-term clinical benefit over RWT in patients with TRD. However,...

Intranasal Dexmedetomidine-Esketamine Combination Premedication versus Monotherapy for Reducing Emergence Delirium and Postoperative Behavioral Changes in Pediatric Tonsillectomy and/or Adenoidectomy: A Randomized Controlled Trial.

Drug Design, Development and Therapy 2024 Yanling Liao, Siyu Xie, Yifen Zhuo et al. 14 citations

Emergence delirium and postoperative negative behavioral changes (PNBC) are common complications in pediatric anesthesia. This study evaluated whether intranasal premedication combining dexmedetomidine and esketamine more effectively reduces these complications compared to either drug alone in children undergoing tonsillectomy and/or adenoidectomy with sevoflurane anesthesia. This randomized,...

From antidepressants and psychotherapy to oxytocin, vagus nerve stimulation, ketamine and psychedelics: how established and novel treatments can improve social functioning in major depression.

Frontiers in Psychiatry 2024 Aleksandra Kupferberg, Gregor Hasler 4 citations

Social cognitive deficits and social behavior impairments are common in major depressive disorder (MDD) and affect the quality of life and recovery of patients. This review summarizes the impact of standard and novel treatments on social functioning in MDD and highlights the potential of combining different approaches to enhance their effectiveness. Standard treatments, such as antidepressants,...

Decreasing brain activity caused by acute administration of ketamine and alcohol - A randomized, controlled, observer-blinded experimental study.

Frontiers in Pharmacology 2024 Luan Oliveira Ferreira, Esther Padilha da Silveira, Clarissa A Paz et al.

Substance abuse is a major public health problem. In recent years, ketamine, which is a parenteral anesthetic, has been consumed increasingly as an illicit drug together with alcohol, although little is known of how this association alters brain activity. The present study investigated the influence of progressive doses of ketamine, associated with alcohol, on electrophysiological activity. For...

Esketamine Nasal Spray: Rapid Relief for TRD and Suicide Prevention-Mechanisms and Pharmacodynamics.

Neuropsychiatric Disease and Treatment 2024 Hui Song, Yang Luo, Lingzhi Fang

Esketamine nasal spray has emerged as a promising rapid-relief therapy for treatment-resistant depression (TRD) and suicide prevention. This review examines the chemical structure and pharmacodynamics of esketamine, highlighting its primary action on NMDA receptors and additional effects on AMPA receptors, opioid receptors, monoaminergic receptors, and inflammatory pathways. Despite the...

Use of esketamine for tracheoscopic drug injection: a randomized controlled trial.

Frontiers in Medicine 2024 Xiaoming Zhao, Zhendong Zhou, Zhenhua Li et al. 3 citations

Sufentanil may induce hypotensive bradycardia and other adverse reactions in elderly patients during anesthesia, while esketamine exhibits sedative and analgesic effects with minimal impact on respiration and circulation. The objective of this study was to investigate the impact of these two anesthetics on vital signs in patients undergoing bronchoscopy and lavage under general anesthesia. This...

Comparative Analysis of Hemodynamic Effects of Remimazolam and Propofol Combined with Esketamine in Colonoscopic Procedures in the Elderly.

Drug Design, Development and Therapy 2024 Bo-Ran Deng, Yang Zhang, Zi-Feng Xie et al. 18 citations

The debate continues over the differential impact of remimazolam vs propofol on hemodynamic stability. This study aims to elucidate the effects of a combination of remimazolam and esketamine vs propofol and esketamine on hemodynamic parameters in elderly patients undergoing painless colonoscopies. We conducted a randomized controlled trial involving 754 patients, divided equally between two...

The amino acid metabolism pathway of peripheral T lymphocytes and ketamine-induced schizophrenia-like phenotype.

Journal of Psychiatry and Neuroscience 2024 Peipei Wang, Linzhi Jiang, Junmei Hu et al. 1 citation

The intricate interplay between peripheral adaptive immune cells and the central nervous system (CNS) has garnered increasing recognition. Given that alterations in cell quantities often translate into modifications in metabolite profiles and that these metabolic changes can potentially traverse the bloodstream and enter the CNS, thereby modulating the progression of mental illnesses, we sought...

Preoperative Anxiety's Impact on the Median Effective Dose of Esketamine for Alleviating Propofol Injection Pain in Patients Undergoing Painless abortion: A Randomized, Double-Blind, Controlled Trial.

Drug Design, Development and Therapy 2024 Yanping Shen, Lijun Yin, Binnan Hu et al. 7 citations

Propofol injection pain (PIP) is a frequent adverse effect during anesthesia induction, impacting patient comfort and satisfaction. Esketamine has been shown to alleviate PIP, but the optimal dose, especially in relation to preoperative anxiety levels, remains unclear. Preoperative anxiety may heighten pain perception and influence analgesic requirements. A randomized, double-blind, controlled...

Dexmedetomidine versus ketamine in improving tolerance to noninvasive ventilation after blunt chest trauma: A randomized, double-blinded, placebo-controlled trial.

Journal of anaesthesiology, clinical pharmacology 2024 Huda F Ghazaly, Mohamed M Elansary, Ahmed A Mahmoud et al. 1 citation

Even though patient tolerance is critical to the success of noninvasive ventilation (NIV), research on using sedation to improve tolerance to NIV after traumatic chest injuries is limited. We hypothesized that dexmedetomidine would be superior to ketamine in terms of patient tolerance and lengthening the NIV sessions after blunt chest trauma. This randomized, double-blinded, placebo-controlled...

KET or ECT for treatment-resistant depression?

International Journal of Psychiatry in Clinical Practice 2024 Marie Spies, Siegfried Kasper, Richard Frey et al.

Modern electroconvulsive therapy (ECT) and ketamine currently represent the most effective treatment options in depressed patients showing non-response to two or more trials of antidepressants. Recently, large sample head-to-head comparisons of intravenous ketamine versus ECT for treatment-resistant depression (TRD) have fuelled the debate on which therapy might be more effective. However, the...

Depression and Anxiety 2024 Ludovic Samalin, Lila Mekaoui, Maud Rothärmel et al. 16 citations

The efficacy and safety of esketamine nasal spray (ESK) were established in registration trials in patients with treatment-resistant depression (TRD). This French real-world study aimed to describe the treatment patterns, effectiveness, and safety of ESK in TRD patients over a 12-month follow-up. This study used secondary data from patient files of hospital-based psychiatrists and started...

Efficacy, Safety, and Tolerability of Psychedelics in Treatment-Resistant Depression (TRD).

Advances in experimental medicine and biology 2024 Berend Olivier, Jocelien D A Olivier 11 citations

Major depressive disorder (MDD) is a highly prevalent psychiatric disorder, associated with substantial burden and large economical costs. Notwithstanding various conventional antidepressant treatment options, a large portion of depressed people (ca. 30%) fails to respond to first-line treatment, resulting in treatment-resistant depression (TRD). Although non-response to multiple antidepressant...
