Background: Major depressive disorder is associated with inflammation and immune processes. Depressive symptoms correlate with inflammatory markers and alterations in the immune system including cytokine levels and immune cell function. Th17 cells are a T cell subset which exerts proinflammatory effects. Th17 cell accumulation and Th17/Treg imbalances have been reported to be critical in the...

Ketamine, a racemic mixture of (S)-ketamine and (R)-ketamine enantiomers, has been used as an anesthetic, analgesic and more recently, as an antidepressant. However, ketamine has known abuse liability (the tendency of a drug to be used in non-medical situations due to its psychoactive effects), which raises concerns for its therapeutic use. (S)-ketamine was recently approved by the United...

Although a substantial number of studies suggests some clinical benefit concerning negative symptoms in schizophrenia through the modulation of NMDA-receptor function, none of these approaches achieved clinical approval. Given the large body of evidence concerning glutamatergic dysfunction in a subgroup of patients, biomarkers to identify those with a relevant clinical benefit through...

Promising initial data indicate that the glutamate N-methyl-D-aspartate (NMDA) receptor antagonist ketamine may be beneficial in post-traumatic stress disorder (PTSD). Here, we explore the neural correlates of ketamine-related changes in PTSD symptoms, using a rich battery of functional imaging data (two emotion-processing tasks and one task-free scan), collected from a subset of participants...

Abstract Severe and enduring eating disorders (EDs) have the highest mortality rate of all psychiatric illnesses (Arch Gen Psychiatry, 2011, 68 , 724), especially when comorbid with treatment‐resistant depression (TRD) (Psychiatr Res, 2016, 244 , 45). We report on four patients with enduring EDs and TRD treated with repeat ketamine over 12 + months, showing improvement in depression with only...

Background Poststroke social isolation could worsen poststroke depression and dampen neurogenesis. (R,S)-ketamine has antidepressant and neuroprotective effects; however, its roles and mechanisms in social isolation–mediated depressive-like behaviors and sensorimotor recovery remain unclear. Methods Mice were subjected to transient middle cerebral artery occlusion, and then were pair-housed...

Dysregulation of glutamate neurotransmission plays a critical role in autism spectrum disorder (ASD) pathophysiology and is a primary target for core deficit research treatment trials. The mechanism of action of ketamine has striking overlap with the theory of ASD as a disorder of synaptic communication and neuronal networks. This two-dose, double-blind, placebo controlled, cross-over pilot...

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...

Introduction The immediate antidepressant effect of Ketamine has become a breakthrough in the treatment of depression. Cytochrome CYP3A4 and 2B6 primarily metabolize Ketamine. Objectives The present study explores potential pharmacokinetic and pharmacodynamic interactions of Lamotrigine and Ketamine. Methods A literature search was conducted using (“ketamine” OR “Lamotrigine” AND Interactions...

MAYBE, but it's too soon to tell. There is limited evidence that ketamine by itself is effective in the very short term. Single-dose intravenous (IV) ketamine is more likely than placebo (odds ratio = 11-13) to produce improvement (> 50%) in standardized depression scores in 1 to 3 days, lasting up to a week. Twice- or thriceweekly IV ketamine improves symptom scores by 20%-25% over 2 weeks...

AbstractBackgroundRepetitive transcranial magnetic stimulation (rTMS) is a safe, effective and non-invasive treatment for many psychiatric illnesses, including treatment-resistant depression (TRD). Ketamine, an NMDA receptor antagonist, is also an effective antidepressant. This retrospective review examined the clinical benefits of combining these two established treatments for patients...

In clinical and laboratory practice, the use of anesthetics is essential in order to perform surgeries. Anesthetics, besides causing sedation and muscle relaxation, promote several physiological outcomes, such as psychotomimetic alterations, increased heart rate, and blood pressure. However, studies depicting the behavioral effect induced by ketamine and isoflurane are conflicting. In the...

Ketamine is an NMDA receptor antagonist with psychotomimetic, dissociative, amnestic and euphoric effects. When chronically abused, ketamine users display deficits in cognition and information processing, even following long-term abstinence from the drug. While animal studies have shown evidence of behavioral changes and cognitive deficits that mimic those seen in humans within the period...

Abstract Inflammation plays a role in depression pathophysiology and treatment response, with effects varying by sex and therapeutic modality. Lower levels of interleukin(IL)-8 predict depression response to antidepressant medication and to electroconvulsive therapy (ECT), although ECT effects are specific to females. Whether IL-8 predicts depression response to ketamine and in a sex-specific...

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...

Background and Objectives: There is evidence for ketamine efficacy in treatment-resistant depression (TRD). Several safety and tolerability concerns arise that some psychotropic agents may provide blood pressure or/and heart rate alterations. The aim of this study is to review blood pressure measurements in course of the treatment with ketamine on treatment refractory inpatients with somatic...

OBJECTIVE: Ketamine has been shown to be effective in treatment of episodes of major depressive disorder (MDD). This controlled study aimed to analyse the predictive and discriminative power of heart rate (HR) and heart rate variability (HRV) for ketamine treatment in MDD. METHODS: In 51 patients, HR and HRV were assessed at baseline before and during ketamine infusion and 24 hours post...

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...

OBJECTIVE Adolescent depression is prevalent and is associated with significant morbidity and mortality.

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...
