Emerging evidence indicates that intravenous ketamine is effective in managing treatment-resistant unipolar and bipolar depression. Clinical studies highlight its favorable efficacy, safety, and tolerability profile within a dosage range of 0.5-1.0 mg/kg based on actual body weight. However, data on alternative dosage calculation methods, particularly in relation to body mass index (BMI) and...
Residual symptoms are frequently observed in a significant number of patients with depression, indicating an unmet need for effective management strategies to achieve functional recovery. This observational study aimed to evaluate the impact of ketamine infusions on depressive symptoms in patients with bipolar disorder who continued their baseline psychotropic and chronic somatic treatments....
Anhedonia induced by sustained stress exposure is a hallmark symptom of major depressive disorder (MDD) and in rodents, it can be accessed through the sucrose preference test (SPT). (R)-ketamine is a fast-acting antidepressant with less detrimental side effects and abuse liability compared to racemic ketamine. The present study combined high-throughput proteomics and network analysis to...
Anorexia nervosa (AN) has one of the highest mortality rates of all mental illnesses. No approved pharmacological treatments exist for AN, but novel neurobiological targets show promise. Studies show that in individuals with AN, there are alterations in brain neurotransmitter signaling, alongside associated mental rigidity and comorbid anxiety and depression. Available and new therapies could...
Mood disorders affect approximately one-third of individuals with epilepsy, posing an increased risk of suicide. There is an unquestionable need for more effective antidepressant treatment in this group of patients. This study explores the safety and tolerability of low-dose intravenous ketamine in six patients with comorbid depression and epilepsy. This report is limited to the post-hoc...

A large number of people worldwide grapple with Major Depressive Disorder (MDD), and a significant portion of them confront resistance to conventional antidepressant treatments. Esketamine, an innovative intervention, has garnered attention due to its rapid-acting antidepressant effects. This meta-analysis aimed to evaluate the efficacy and safety of esketamine in individuals with MDD and...
Arketamine, the (R)-enantiomer of ketamine, exhibits both therapeutic and sustained prophylactic effects in an inflammation-driven model of depression, although the precise mechanisms remain elusive. Given the involvement of γδ T cells in inflammatory processes, this study explored their role in the effects of arketamine. To assess therapeutic outcomes, mice received lipopolysaccharide (LPS:1.0...
Esketamine nasal spray (ESK) is approved, in conjunction with an oral antidepressant, for the treatment of treatment-resistant depression in adults and for the treatment of depressive symptoms in adults with major depressive disorder with acute suicidal ideation or behavior. No adverse events (AEs) of respiratory depression were reported in ESK phase 3 clinical trials; however, postmarketing...

This case study examines the novel application of Spravato (intranasal esketamine) to address treatment-resistant Major Depressive Disorder (MDD) in an 86-year-old patient. Notably, this represents one of the oldest documented individuals to be administered intranasal esketamine for a diagnosis of Treatment-Resistant Depression (TRD) alongside suicidal ideation. This case study contributes to...
Depression and pain are common comorbidities in cancer patients, and ketamine, a dissociative anesthetic, has shown potential in managing both. This review summarizes current literature on ketamine and its enantiomer, esketamine, in managing depression and pain in the oncologic population. Studies indicate that sub-anesthetic doses of intravenous ketamine and esketamine can alleviate...
