Nitrous Oxide

Nitrous oxide (N₂O) is a rapid-acting NMDA receptor antagonist with emerging evidence for antidepressant efficacy in treatment-resistant depression. Delivered as a 50% N₂O/50% O₂ inhalation mixture over one-hour sessions, it produces rapid mood improvements that can persist for days to weeks. Its established safety record in anesthesia, short session duration, minimal recovery time, and low cost position it as a potentially scalable alternative to IV ketamine and esketamine, though the psychiatric evidence base remains early-stage and no formal psychiatric indication exists. Key open questions include optimal dosing frequency, long-term durability, and the mechanism by which NMDA antagonism without intense psychedelic phenomenology produces antidepressant effects.

Full Nitrous Oxide profile
IndicationApproximately 300 million adults worldwide struggle with depression, many of whom are older adults.

Older Adults

Psychedelic research involving older adults is gaining traction, highlighting the potential therapeutic benefits of compounds such as psilocybin and MDMA. Recent studies suggest promising safety profiles and efficacy, paving the way for future clinical applications in this demographic.

Nitrous oxide as an adjunctive therapy in major depressive disorder: a randomized controlled double-blind pilot trial

This double-blind placebo-controlled between-subjects study (n=23) tested the antidepressant efficacy of inhaled nitrous oxide (50% N2O|50% O2 versus 100% O2) in patients diagnosed with major depression (MDD). Across multiple treatment sessions administered across a period of 4 weeks, there were significant reductions in depressive symptoms in the acute response to treatment and accumulatively across sessions.
