Depression and its severe outcomes, suicidal ideation and behavior, are exacerbated by stress. A broad literature links dysregulation of the hypothalamic-pituitary-adrenocortical (HPA) stress response system to depression, suicidal ideation and behavior. Our midazolam-controlled clinical trial of subanesthetic, intravenous ketamine infusion for suicidal depressed patients found rapid reduction...

Suicide is a major cause of death worldwide and a key public health challenge. Pharmacologic and neuromodulatory interventions are central to suicide prevention. This review summarizes evidence for these interventions with potential antisuicidal effects across major psychiatric disorders and, where possible, distinguishes their direct effects on suicide diathesis from those mediated by...

Suicide is a global public health problem with few empirically supported treatments. We conducted a systematic review of clinical trials (CT) since 2020 of racemic ketamine or one of its enantiomers' (R/S) potential to reduce suicidal ideation or behavior (SIB). An initial PubMed search on April 15th, 2024 yielded 2483 results. 104 relevant CTs were identified. An additional search using other...

We sought to explore relationships of acute dissociative effects of intravenous ketamine with change in depression and suicidal ideation and with plasma metabolite levels in a randomized, midazolam-controlled trial. Data from a completed trial in suicidal, depressed participants (n = 40) randomly assigned to ketamine was used to examine relationships between ketamine treatment-emergent...

Abstract Depression is disabling and highly prevalent. Intravenous (IV) ketamine displays rapid-onset antidepressant properties, but little is known regarding which patients are most likely to benefit, limiting personalized prescriptions. We identified randomized controlled trials of IV ketamine that recruited individuals with a relevant psychiatric diagnosis (e.g., unipolar or bipolar...
