What Is Esketamine?
Esketamine is a pharmaceutical drug derived from ketamine. It is typically sold under the brand names Ketanest and Spravato. Similar to ketamine, esketamine acts as an anesthetic and a dissociative that is used to treat Treatment-Resistant Depression (TRD).
In March of 2019, the FDA approved esketamine in the form of a nasal spray for the effective treatment of Major Depressive Disorder for people who have not been successful with traditional antidepressant treatments.
