A new study at the University of Chicago Medicine and Washington University found that a single inhalation session with 25% nitrous oxide gas was nearly as effective as 50% nitrous oxide at rapidly relieving symptoms of treatment-resistant depression, with fewer adverse side effects. The study, published June 9 in Science Translational Medicine, also found that the effects lasted much longer than previously suspected, with some participants experiencing improvements for upwards of two weeks.
These results bolster the evidence that non-traditional treatments may be a viable option for patients whose depression is not responsive to typical antidepressant medications. It may also provide a rapidly effective treatment option for patients in crisis.
