About this trial

Patients with depression are acutely distressed, often suicidal, and unable to meet the demands of everyday life. If proven effective in a rigorously conducted multicenter randomized controlled trial (RCT), oral ketamine would provide an affordable and scalable, intervention suitable for integration into routine psychiatric services.This study will establish an indigenous, cost-effective therapeutic strategy that could improve accessibility, hasten therapeutic response, and inform treatment guidelines, if found to be safe and effective.
