Case report of S-ketamine as treatment option for suicidal ideation and treatment-resistant depression in adolescents with early-onset psychosis

Neuropsychiatrie August 25, 2026 Nicolas Schmelzle, Katrin Neubacher, Paul L. Plener et al.

BACKGROUND: Depressive symptoms and suicidality are highly prevalent in adolescents with early-onset psychosis (EOP) and often remain refractory to standard treatment. While S‑ketamine is an established treatment for treatment-resistant depression in adults (TRD), its use in primary psychotic disorders remains scarce due to risk of exacerbation of psychotic symptoms. CASE PRESENTATION: We...

Profiling intranasal esketamine for adults with major depressive disorder and acute suicidal ideation or behavior: a phenotype-informed drug profile

Expert Review of Neurotherapeutics August 18, 2026 Mario Pinzi, Alessandro Cuomo, Maria Beatrice Rescalli et al.

INTRODUCTION: Acute suicidal ideation in major depressive disorder (MDD) is a psychiatric emergency requiring rapid risk assessment, containment, and treatment. Conventional monoaminergic antidepressants have delayed onset, leaving an interval during which severe depressive distress persists. Intranasal esketamine, a rapid-acting N-methyl-D-aspartate receptor antagonist, is approved for MDD...

A Systematic Review of Long-term Safety Outcomes of Ketamine and Esketamine in Patients with Treatment-resistant Depression.

August 17, 2026 Tychique T. Wasolua, Morgan S. Hardy, Tanner J. Bommersbach et al.

INTRODUCTION: Approximately 30-40% of patients with major depressive disorder fail to respond to conventional antidepressants. Ketamine and esketamine are increasingly used, yet synthesized data on cumulative safety remain limited. This systematic review evaluated long-term safety of both agents. METHODS: MEDLINE, PsycINFO, Embase, and Cochrane Library were searched from inception through...

Exploratory non-randomized clinical trial of subcutaneous esketamine in treatment-resistant depression: Effects of ketamine-assisted psychotherapy

Journal of Affective Disorders August 10, 2026 Yves Martins Varela, Patrícia Cavalcanti-Ribeiro, Geovan Menezes de Sousa et al.

BACKGROUND: Ketamine is an effective rapid-acting treatment for treatment-resistant depression (TRD), producing antidepressant effects within hours of administration. Because it induces states of heightened neuroplasticity and psychological openness, psychotherapy may enhance its therapeutic effects. METHODS: This exploratory, nonrandomized, open-label clinical trial evaluated the adjunctive...

Shared Decision-Making Music Therapy With Esketamine for Treatment-Resistant Depression

The Journal for Nurse Practitioners August 10, 2026 Tanner Herb, Heeyoung Lee, Prabir Mullick et al.

This quality improvement project examined the impact of shared decision-making–guided music intervention integrated into esketamine treatment on depressive symptoms and quality of life in 10 adults with treatment-resistant depression at a private psychiatric clinic. Over 4 months, patients collaborated with their providers to select and listen to music during each session. Depressive symptoms...

The molecular and neurochemical basis of altered intrinsic neural timescales in major depressive disorder: a multimodal imaging-transcriptomic investigation of esketamine and sertraline treatment

BMC Psychiatry August 5, 2026 Xiang Liu, Yuanzhi He, Lifeng Li et al.

Abstract Introduction Major depressive disorder (MDD) is characterized by dysfunction in higher-order cortical regions involved in emotional and cognitive processes; however, its neurobiological basis remains unclear. Pharmacological treatments, including esketamine and sertraline, produce rapid antidepressant effects. We investigated the local intrinsic neural dynamics underlying these...

New treatments for treatment-resistant depression: esketamine controversies - a narrative review.

Danish medical journal August 4, 2026 Maj Vinberg

This narrative review examines barriers to Danish patients' timely access to new treatments for treatment-resistant depression, focusing on controversies around esketamine. Delays arise from regulatory complexity, economic constraints and scientific debate over novel psychotropics. The review advocates evidence-based, faster implementation pathways for new treatments to alleviate the overall...

Real-world clinical practice, effectiveness and safety of esketamine nasal spray in major depressive disorder patients: a French prospective cohort (ELLIPSE study)

Therapeutic Advances in Psychopharmacology August 1, 2026 Pierre-Michel Llorca, Anne Sauvaget, Emilie Olié et al.

Background: Major depressive disorder (MDD) is highly prevalent and associated with significant disability and mortality. Treatment-resistant depression (TRD), defined as inadequate response to ⩾2 antidepressant lines, remains a major therapeutic challenge. Esketamine nasal spray, approved in 2019 for TRD, demonstrated efficacy and safety in randomized trials, but real-world evidence remains...
