Background: Esketamine is a rapidly acting antidepressant with robust efficacy in treatment-resistant depression (TRD). Diminishing therapeutic effects and attenuated side effects have been reported after long-term use. This study aimed to investigate its long-term pharmacokinetics and factors that may contribute to reduced efficacy over time in patients with TRD by evaluating the potential...

The concomitant presence of major depressive disorder (MDD) and opioid use disorder (OUD) poses a formidable clinical challenge, warranting effective interventions that address both psychiatric and addictive components. This study sought to compare the efficacy of adjunctive ketamine and buprenorphine in mitigating anxiety symptom severity and craving intensity in individuals with co-occurring...

Childhood trauma is a well‐established risk factor for major depressive disorder (MDD) and is often associated with attenuated response to conventional antidepressant therapies. Ketamine has emerged as an effective treatment for treatment‐resistant depression (TRD), but the impact of childhood trauma on its effectiveness remains unclear. Herein, we aimed to determine whether childhood trauma...

Background Postoperative depression (POD) represents a serious complication in surgical patients, exacerbating morbidity and mortality rates while imposing a substantial economic burden on healthcare systems. Despite its widespread clinical use, the role of esketamine, an NMDA receptor antagonist with rapid antidepressant effects, remains understudied in perioperative settings. Therefore, we...

Ketamine is known for its rapid antidepressant effect, but its impact on affective information processing (including attentional bias [AB], a putative cognitive mechanism of depression) remains largely unexplored. We leveraged a novel measurement of AB and sought to 1) establish adequate test-retest reliability and validity among participants with depression prior to ketamine treatment and 2)...

Non-alcoholic fatty liver disease (NAFLD) has been associated with depression and inadequate response to antidepressants. While ketamine has demonstrated efficacy in treating depression, its impact on pre-existing liver injury and depression remains unclear. This study aimed to evaluate the effects of ketamine treatment in a murine model of depression and liver damage, considering age-related...

In this case report, we present a patient with treatment-resistant depression (TRD) and comorbid generalized anxiety disorder, eating disorder, post-traumatic stress disorder, and borderline personality disorder. Over a 10-year period, our case transitioned from adolescence to adulthood and received antidepressant monotherapy, adjunctive therapy with antipsychotics, lithium, or lamotrigine,...

Esketamine is administered intranasally in combination with at least another antidepressant in patients with treatment-resistant depression. Some of these antidepressants might affect ketamine's pharmacokinetic profile by inhibiting cytochrome-P450 (CYP450) isoforms. Our aim was to establish how different types of combined antidepressants affect serum and salivary levels of esketamine at the...

Introduction: Depression, affecting 350 million people globally, is a leading cause of disability. Common symptoms include low mood, sadness, guilt, anxiety, and suicidalthoughts. Current treatments, mostly monoamine-based antidepressants, have limitations such as delayed effects and low efficacy, with over 60% of patients not achieving lasting remission. Ketamine, an NMDA antagonist, has shown...

Ketamine is a rapid-acting treatment for treatment-resistant depression (TRD), though mechanisms related to ketamine's effects remain unclear. Blood-based neurotrophic and inflammatory factors (NIFs; e.g., brain-derived neurotrophic factor, interleukin-6) have emerged as markers potentially linked to ketamine and ketamine treatment response. In this secondary analysis of a randomized controlled...
