Nitrous oxide may possess antidepressant effects; however, limited data exist on repeated administrations and active placebo-controlled studies in treatment-resistant depression (TRD). We aimed to test the feasibility of a randomised controlled trial examining a 4-week course of nitrous oxide or midazolam, an active placebo. In this randomised, active, placebo-controlled pilot trial, 40...

Despite ketamine's promising results in treating depression, a significant number of patients do not respond to the treatment, and predicting who will benefit remains a challenge. Although its antidepressant effects are known to...

Thus, we aim to examine the feasibility and preliminary efficacy of a six-week follow up study examining the effects of a 4 week...
