Major depressive disorder (MDD) and posttraumatic stress disorder (PTSD) are debilitating psychiatric conditions associated with poor health outcomes similarly observed in non-pathological aging. Ketamine is a dissociative anesthetic and NMDA receptor antagonist with demonstrated rapid reduction in symptoms associated with Treatment Resistant Depression (TRD) and PTSD. Ketamine's effects on...

Background: Treatment-resistant depression (TRD) affects up to a third of patients with major depressive disorder and remains difficult to manage with conventional therapies. Rapid-acting antidepressants targeting the glutamatergic system, such as ketamine, esketamine, and dextromethorphan-bupropion, have emerged as promising alternatives. Nitrous oxide, also an NMDA receptor antagonist, has...

BACKGROUND: Over the past ten years, several psychedelic compounds, including tryptamines like lysergic acid diethylamide/LSD, psilocybin, ayahuasca, and dimethyltryptamine/DMT, have been tested in clinical trials for a range of psychiatric conditions, such as anxiety and depression. While these compounds are relatively available for treatment, ketamine and its S(+) enantiomer, esketamine, are...

INTRODUCTION: Functional impairment is commonly reported amongst individuals with major depressive disorder (MDD) or treatment-resistant depression (TRD). Extant evidence suggests that ketamine and esketamine, N-methyl-D-aspartate (NMDA) receptor antagonists and glutamatergic modulators, have shown efficacy in treating MDD/TRD. While symptom reduction remains central to treatment, many...

Background: Comorbid depressive symptoms are prevalent in patients with breast cancer, which adversely impacts postoperative recovery outcomes. Esketamine has emerged as a promising intervention for perioperative depression due to its rapid and sustained effects. This study aims to investigate the impact of the continuous intravenous infusion of esketamine during the perioperative period on...

Background Ketamine and esketamine have demonstrated rapid, short-term antidepressant effects in major depressive disorder (MDD), but their relative safety remains unclear. This review aims to update the evidence on the safety of two agents for MDD and indirectly compare their safety and tolerability. Method We systematically searched PubMed, PsycINFO, Embase, and Cochrane databases up to 1 May...

Background: Depression is a common complication of Parkinson disease (PD). This study investigated whether a single dose of esketamine could alleviate depressive symptoms in an MPTP mouse model by activating G protein-coupled receptor 109 A (GPR109A) and reducing neuroinflammation. Methods: Adult male C57BL/6 J mice (8 weeks, 25–30 g) were allocated into three groups: saline,...

Ketamine-assisted therapy is emerging as a fast-acting intervention for treatment-resistant depression and anxiety. However, individual response to treatment varies, and little is known about how personality traits and trauma history influence outcomes. This study investigated whether distinct personality profiles emerge in a real-world sample of patients undergoing ketamine therapy and...

More than 280 million individuals worldwide suffer from depression, which is one of the main causes of mental disability. It has multiple subtypes, and conventional treatments have limitations such as slow onset of action, high non-response rate, and numerous side effects. For instance, it takes two to six weeks for selective serotonin reuptake inhibitors (SSRIs) to start working, and about 30%...

Depression, projected to be the leading cause of global disability by 2030, affects up to 19.62% of Pakistan's population. Treatment-resistant depression (TRD), characterized by poor response to at least two antidepressants, poses a major clinical challenge. Although interventions like ECT exist, their use is limited by systemic barriers. Esketamine, an NMDA receptor antagonist, offers a...
