Johnson & Johnson has received FDA approval for Spravato nasal spray as the first and only monotherapy for adults with treatment-resistant depression.

The U.S. Food and Drug Administration has approved a nasal spray to treat depression—the first-ever stand-alone medication for patients with severe depression. Johnson & Johnson said patients who use the nasal spray Spravato—which is made from the drug esketamine—may see improvements in depressive symptoms in as little as 24 hours.
