Although electroconvulsive therapy (ECT) is the standard treatment for Stage 2 or higher treatment-resistant depression, it has several drawbacks. Repetitive transcranial magnetic stimulation (rTMS) and intravenous racemic ketamine (IV ketamine) have emerged as potential alternatives, but their comparative effectiveness and safety remain unclear due to limited evidence. We systematically...
BACKGROUND Intravenous racemic ketamine is a promising treatment for treatment-resistant depression. However, its clinical utility compared with intranasal esketamine and the other well-studied conventional pharmacological interventions (i.e., aripiprazole and lithium) as augmentative treatments for treatment-resistant unipolar depression in adults remains unclear. Therefore, we aimed to...
