Sex and individual differences in ketamine's effects on alcohol drinking in rats.

Alcohol Clin Exp Res March 1, 2026 Sarah D Jennings, Ian Yates, Samantha K Saland et al.

Background: Effective pharmacotherapies for Alcohol Use Disorder (AUD) are lacking, and factors such as sex, drinking patterns, and timing of treatment during the addiction cycle may influence treatment efficacy. Clinical studies suggest that ketamine may be effective in AUD; however, preclinical findings have been inconclusive, likely due to varying rodent strains, intake protocols, and...

A systematic review and meta-analysis of the efficacy of ketamine compared to electroconvulsive therapy for treatment-resistant depression.

International Journal of Psychiatry in Clinical Practice March 2026 Guoguang Song, Ugwah-Oguejiofor Chinenye Jane

Electroconvulsive therapy (ECT) has long been considered the main method of treatment for patients with resistant major depressive disorder (MDD). Recent studies have shown that ketamine infusion can also effectively improve treatment-resistant MDD. Thus, we conducted this meta-analysis to compare the efficacy of ketamine with ECT for treating treatment-resistant depression. We systematically...

A Blueprint for Implementing Ketamine-Assisted Psychotherapy in Palliative Care: Design, Process, and Treatment Patterns of a Real-World Clinical Program.

Journal of Palliative Medicine March 1, 2026 Robert K Horowitz, William E Rosa, Ali John Zarrabi et al.

Psychospiritual distress (PSD) causes profound suffering in people with serious illness, yet treatment options are few and evidence of their efficacy is modest. Although high-level evidence is limited, decades of preliminary research suggest that psychedelic-assisted psychotherapy (PAP), including ketamine-assisted psychotherapy (KAP), may alleviate the anxiety, depression, and existential...

Single fixed-dose intranasal racemic ketamine treatment for the treatment of acute suicidality in a transdiagnostic patient population: Results of a pilot study.

Psychiatry Research March 1, 2026 Gijsbrecht H. J. Roelandt, Jurriaan F M Strous, Radboud M Marijnissen et al. 1 citation

Ketamine has been shown to decrease suicidality in patients with depression. However, little is known about tolerability and efficacy in heterogenous, acutely suicidal patients in emergency settings. This pilot study aimed to assess the feasibility, acceptability, and safety of generic intranasal racemic ketamine (75 mg) in the treatment of acute suicidality regardless of the underlying...

Brain State Dynamics in Ketamine-Induced Dissociation Resemble Those in Posttraumatic Stress Disorder.

Biological Psychiatry Global Open Science March 1, 2026 Noam Goldway, Taly Markovits, Naomi Fine et al. 1 citation

Dissociation, an altered state of consciousness in which individuals feel detached from their body, environment, and sense of self, is a common feature of posttraumatic stress disorder (PTSD). Despite its significance, the neurocognitive processes underlying dissociation remain poorly understood, potentially limiting diagnostic precision and treatment efficacy in PTSD. To address this gap, we...

The Montreal model of ketamine-therapy for alcohol use disorder and comorbid treatment-resistant depression: protocol for a feasibility trial

BMJ Open March 1, 2026 Christina Mcanulty, Philippe Lavoie, Samuel Cyr et al.

BACKGROUND: Alcohol use disorder and treatment-resistant depression (TRD) often co-occur, presenting a major clinical challenge with limited effective treatments. However, ketamine produces rapid antidepressant effects and has shown promise in reducing alcohol use, and acceptance and commitment therapy (ACT) can be effective for both substance use and mood disorders. This study explores the...

Pink Walls: Depression, Ketamine, and Chronicity

WSQ: Women's Studies Quarterly March 1, 2026 Susan Merrill Squier

Abstract: After an episode of painful ovarian torsion, I accepted a surgeon's counsel to undergo a hysterectomy/oophorectomy at the age of forty-six. The sudden menopause this surgery brought on intensified a chronic depression. Several decades later, after undergoing ketamine infusion treatments for my depression, I recognized that surgery as an experience of iatrogenic harm, part of the...

Ketamine-Prazosin Combined Pharmacotherapy in Post-Traumatic Stress Disorder and Alcohol Use Disorder: Targeting Complementary Neurobiological Mechanisms.

The Nursing clinics of North America March 1, 2026 Amanda Canada

Posttraumatic Stress Disorder (PTSD) and Alcohol Use Disorder (AUD) often co-occur, worsening outcomes, relapse rates, and treatment response. Ketamine produces rapid and sustained PTSD symptom reduction and reduces AUD relapse. Prazosin effectively treats PTSD-related nightmares and may reduce alcohol consumption in individuals with heightened autonomic reactivity. The dual complementary...

Ketamine and Esketamine Therapy in Affective Disorders: A Comprehensive Review of Mechanisms, Clinical Evidence, Safety, and Future Directions

Zenodo (CERN European Organization for Nuclear Research) February 28, 2026 Kshirsagar Pankaj*, Misal Shivdarshan, Dr. Giri Ashok preprint

Major Depressive Disorder (MDD) and Bipolar Depression represent significant global health burdens because about one-third of patients who receive standard monoaminergic antidepressant treatment fail to achieve remission. The population with Treatment-Resistant Depression (TRD) needs assistance because they deal with dangerous suicide risks and struggle with their daily activities. The review...

Ketamine pharmacotherapy for major depressive disorder: A narrative review

Progress in Neuro-Psychopharmacology and Biological Psychiatry February 27, 2026 Chris H. Miller, Angela Hickman, Caitlin Baten et al. 2 citations

Ketamine pharmacotherapy provides a novel treatment option for major depressive disorder (MDD) and has generated a large, growing body of research regarding its biochemical and clinical properties. This narrative review summarizes the history of ketamine's development, beginning as a general anesthetic, continuing with a discovery of its antidepressant properties, and leading up to its landmark...
