Background Ketamine represents a significant advancement in antidepressant therapy, but the commonly used intravenous and intranasal application routes currently limit its availability beyond specialized centers. By contrast, oral ketamine treatment might constitute an alternative that is easy to administer with established safety and efficacy for patients with chronic and severe pain at home.
Subanesthetic doses of (R,S)-ketamine (ketamine) have demonstrated rapid and robust antidepressant effects in individuals with depression. However, individual variability in response to ketamine exists, and current biomarkers of ketamine treatment response are not entirely understood. Preclinical evidence suggests a link between hypothalamic-pituitary-adrenal (HPA) axis activation, a...
Ketamine's potential for treating depression has drawn increased clinical interest in recent years. However, despite growing therapeutic use, recreational use among individuals with depression remain underexplored. We analyzed data from the 2015-2022 National Survey on Drug Use and Health focusing on adults in the US. Trends in past-year ketamine use, overall and by depression status, were...

Patients suffering from treatment-resistant depression may be treated with nasal esketamine. The treatment requires administration in a healthcare facility and monitoring by a nurse. Existing research has mainly focused on the clinical effect of nasal esketamine, while less is known about patients' experiences of treatment. A person-centred framework provides valuable insights into care and...
To evaluate the efficacy, safety, and tolerability of esketamine nasal spray vs psychoactive placebo (oral midazolam) in rapidly reducing depressive symptoms in adolescents with major depressive disorder at imminent risk for suicide. This double-blind, double-dummy, phase 2b study randomized (1:1:1:2) 147 adolescents (12 to <18 years old) to esketamine (28, 56, or 84 mg) or midazolam twice...
In this editorial, we comment on a recent article by Chen et al, that addressed the effect of intraoperative injection of esketamine on postoperative analgesia and postoperative rehabilitation after cesarean section. Poor management of post-cesarean pain is associated with decreased maternal care for the baby, longer hospitalization, and higher risk of developing postpartum depression....
Objective: To compare efficacy and safety outcomes for ketamine anesthesia + electroconvulsive therapy (ECT) versus nonketamine anesthesia + ECT in treatment-resistant depression (TRD) patients. Data Sources: PubMed and Embase were searched from the earliest date through November 27, 2023. Study Selection and Data Extraction: Relevant randomized controlled trials (RCTs) of ketamine + ECT versus...
Modern electroconvulsive therapy (ECT) and the approval of nasal esketamine for clinical use have significantly improved the approach to treatment-resistant depression (TRD), which is defined as non-response to at least two different courses of antidepressants with verified adherence to treatment, adequate dosage, and duration of treatment. The goal of this literature review is to present the...
This analysis sought to identify potential clinical targets for the suicide crisis. Characteristics of a useful clinical target include elevation at the time of suicide crisis and responsiveness to rapid-acting interventions. Suicidal ideation (SI), depression, and hopelessness were hypothesized to meet these criteria. Participants were 118 adults across the continuum of suicide risk, including...
Esketamine has demonstrated acute antidepressant effects in patients with major depressive disorder (MDD). This study investigated whether these effects associate with reversible white matter fiber integrity recovery using diffusion imaging. Twenty patients with MDD and 20 healthy controls received 2-week esketamine treatment. Patients received 0.25 mg/kg intravenous esketamine. Emotional and...
