Hepatic Safety of Ketamine and Esketamine for Treatment-Resistant Depression: A Real-World Cohort Study.
npj Mental Health Research July 27, 2026 Jennifer Swainson, P. Grewal, S. Polard et al.
This scoping review maps literature for use of ketamine or esketamine with psychotherapy for depression or depressive symptoms. Forty-seven studies were identified including 4/47 (9%) randomized controlled trials, 4/47 (9%) open label trials, 27/47 (57%) observational or retrospective studies, and 12/47 (26%) individual case reports. Studies were categorized as Ketamine/Esketamine Combined with...

Background: Pharmacologic treatment options for borderline personality disorder (BPD) remain limited, and no medication has received regulatory approval for its treatment. Given the high rates of comorbid depression and suicidal ideation in BPD, there is growing interest in novel therapeutic approaches. Ketamine has been approved for treatment-resistant depression and acute suicidality, raising...

Esketamine has been approved for the treatment of treatment-resistant depression. However, there is an unmet clinical need to extend the duration of esketamine's action to reduce the high recurrence rate after drug withdrawal and the potential side effects of repeated esketamine use. Here, we found that increasing extracellular signal-regulated kinase (ERK) activity by pharmacologically...

GABAergic inhibitory interneurons balance brain activity by suppressing excessive excitatory signaling and shaping network oscillations. Despite this critical function, our understanding of how neural circuits regulate GABAergic systems remains limited. Although N-methyl-D-aspartate receptor (NMDAR) functionality is defined by the GluN2A-D subunits, the interneuron NMDAR subunit composition...

Esketamine in Treatment-Resistant Depression: Clinical and Translational Perspectives.

Esketamine nasal spray (NS) is an established treatment for patients with treatment resistant depression (TRD). To further optimise real-world outcomes, consensus is needed regarding strategies to enhance patient outcomes and decision-making factors for pivotal timepoints in esketamine NS treatment. This modified Delphi panel (3 rounds) established expert consensus (≥80% agreement) from 30...

Major depressive disorder is a highly burdensome psychiatric condition worldwide, and many patients do not achieve full remission after standard monoaminergic antidepressant treatment. This has contributed to growing interest in rapid-acting antidepressant interventionstargeting neurobiological pathways beyond traditional serotonin, norepinephrine, and dopamine mechanisms. This review...

Ketamine and its enantiomer esketamine are efficacious in 30-35% of the patients with treatment-resistant depression (TRD). Increased serum brain-derived neurotrophic factor (BDNF) following treatment has been proposed as a potential biomarker of antidepressant response. This is based on studies evaluating single intravenous ketamine treatment. BDNF expression at different treatment schedules...
