Objectives Ketamine and esketamine are increasingly used for treatment-resistant depressive disorders, particularly when rapid symptom reduction is clinically desirable. Intranasal esketamine has a product-specific regulatory framework in several jurisdictions, whereas most racemic ketamine formulations remain off-label for psychiatric indications. This narrative review provides practical...

Mood disorders, including major depressive disorder (MDD) and bipolar disorder (BP), significantly impact global health, with MDD affecting over 300 million people and BP affecting approximately 2% of the world's population. Ketamine, originally an anesthetic, has emerged as a promising treatment for patients with treatment-resistant depression (TRD), due to its unique pharmacological...

Ketamine, an N-methyl-D-aspartate receptor antagonist, is a racemic mixture of esketamine and arketamine used to treat unipolar and bipolar depression. Preliminary reports indicate that it may be beneficial for depressed patients reporting symptoms of anhedonia. In this systematic review we aim to assess and analyze the existing body of evidence regarding the therapeutic effects of ketamine on...

Ketamine is the prototypal rapid-acting antidepressant (RAAD) for TRD with approved indication for esketamine-nasal spray (ESK-NS). Distinctly, arketamine (R-KET) demonstrates enhanced antidepressant effects and neuroplasticity changes compared to esketamine, with fewer dissociative side effects and abuse potential. This study focuses on R-ketamine's therapeutic implications, safety, and...

Purpose: Approximately 30% of patients with major depressive disorder (MDD) are treatment resistant. There is an unquestionable need for new treatment strategies. Subanesthetic doses of intravenous (IV) ketamine have a rapid antidepressant effect in treatment-resistant depression (TRD). This paper describes the efficacy of repeated series of intravenous ketamine infusions as an add-on treatment...

Relationship between depression and magnesium levels is reported. This observational study examined whether serum magnesium concentration change over time of ketamine treatment course, also whether association between magnesium concentrations and treatment response measured with Montgomery-Åsberg Depression Rating Scale (MADRS) score occurs. Moreover, interlink between changes in Young Mania...

Changes in serum copper concentration are observed in patients with depressive symptoms. Unmet needs in contemporary antidepressant treatment have increased interest in non-monoaminergic antidepressants, such as ketamine, an anaesthetic drug that has demonstrated a rapid antidepressant effect in patients with treatment-resistant depression (TRD). The purpose of this study was to examine whether...

There is a growing evidence for the rapid and robust antidepressive effect of ketamine in unipolar and bipolar treatment resistant depression although evidence for the risk of affective switch is still limited. This case presents bipolar I disorder patient with treatment resistant depressive episode experiencing a switch to manic episode with mixed features shortly after receiving eight...

Depression is one of the major causes of disability worldwide. A proportion of adults with major depression fail to achieve remission with first-line treatment. Magnesium influences the neurotransmission involved in emotional processes, such as the serotonergic, noradrenergic, dopaminergic, GABAergic and glutamatergic systems. It has been reported that the mechanism of antidepressants' action...

Impulsive behaviours affect patients with major depressive disorder (MDD) and bipolar disorder (BP), increasing suicide risk and mood instability. Ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist, has been reported to promote fast-acting antidepressive and antisuicidal effects. Magnesium administered contemporarily with low-dose NMDA antagonists has been shown to cause a reduction...
