Esketamine Monotherapy Shows Rapid Relief for Treatment-Resistant Depression
Can Esketamine Work Alone Without Other Antidepressants for Treatment-Resistant Depression?
Yes. Esketamine nasal spray works effectively as monotherapy for treatment-resistant depression, with significant improvements observed within 24 hours of the first dose and sustained through 28 days of treatment. A randomized clinical trial published in JAMA Psychiatry shows both 56mg and 84mg doses administered twice weekly provide rapid and clinically meaningful improvement compared to placebo, offering a standalone treatment option for patients who cannot tolerate or have not responded to oral antidepressants.
