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...

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...

Ketamine has been established as an anesthetic agent for decades.

These findings established the concept of an effective glutamatergic antidepressant treatment and initiated a paradigm shift. For many years, intravenous...
