The FDA just approved a new antidepressant, the first of its kind. Unlike other antidepressants, this one is a nasal spray. Esketamine, under the brand name Spravato, is developed by Johnson & Johnson and has been in testing for the past 2 years. The drug has seen remarkable success. This success is interesting because the drug is closely tied to the club drug “Special K.” Related to MDMA, Special K is known as Ecstasy. This marks the first major breakthrough in the treatment of depression since the 1980s.
