The Food and Drug Administration has approved a new nasal spray for the treatment of severe depression.
On Tuesday, the government agency announced Spravato nasal spray, also known as esketamine, can now be used "for the treatment of depression in adults who have tried other antidepressant medicines but have not benefited from them."
"There has been a long-standing need for additional effective treatments for treatment-resistant depression, a serious and life-threatening condition," said Dr. Tiffany Farchione, acting director of the Division of Psychiatry Products in the FDA's Center for Drug Evaluation and Research, in a statement.
The FDA said patients with major depressive disorder who have tried at least two antidepressants are considered to have treatment-resistant depression.
It is estimated that approximately one-third of U.S. adults with a major depressive disorder have treatment-resistant depression, according to Janssen Pharmaceutical Companies of Johnson & Johnson, which developed Spravato.

FDA approved nasal spray, known as esketamine, to treat major depression is biggest advance in years
