Could inhaling nitrous oxide treat major depression?
A phase 2 trial published in a peer-reviewed journal shows promising results with a low rate of adverse events at low doses
Inhaled nitrous oxide can effectively treat severe treatment-resistant major depression for up to two weeks, reports a phase 2 trial.
The crossover study included 24 patients with sustained and refractory depressive illness who were treated in random order with a single one-hour inhalation of either 25% or 50% of nitrous oxide or placebo (air/oxygen).
