Among patients with treatment-resistant depression who continued esketamine nasal spray for at least six months, 76.2% responded or achieved remission. Of those who had not responded by six months, a subset improved by twelve months. Side effects occurred in 71.8% of patients at six months, decreasing to 42% at twelve months; the most common were sedation and dissociation. Only two patients stopped treatment due to tolerability issues. The findings suggest esketamine is effective and safe for mid- to long-term treatment, with a novel observation of late clinical response in some patients. Results require confirmation in larger samples and longer observation periods.

In patients with treatment-resistant depression, combining vortioxetine with esketamine nasal spray reduces depressive symptoms as effectively as the standard combination of an SSRI or SNRI with esketamine. The vortioxetine combination also showed a larger reduction in emotional blunting after three months and had fewer treatment-emergent side effects. These findings come from a post-hoc analysis of twenty patients, ten in each group. The authors suggest the vortioxetine-plus-esketamine regimen may be a valuable alternative, but they call for larger randomized controlled trials to confirm the results.

Over six months of routine esketamine treatment for treatment-resistant depression, depressive symptoms and daily functioning both improved progressively. By month six, 78.3% of patients showed a symptomatic response and 46.7% reached symptomatic remission, while 78.3% showed a functional response but only 33.3% achieved functional remission. Functional remission accumulated more slowly than symptomatic remission, with cumulative rates of 5% at one month, 15% at three months, and 33.3% at six months. Higher baseline disability and more previous antidepressant trials were linked to lower odds of functional remission at six months. The findings suggest that functional improvement follows a distinct trajectory from symptom improvement and should be monitored separately in treatment-resistant depression.
