The depression drug esketamine, marketed as Spravato, appears to offer quick relief to people who are actively considering suicide.

Esketamine, a chemical cousin of the anesthetic and party drug ketamine, reduced depression symptoms within hours in two large studies of suicidal patients, the drug's maker announced Monday.

The Food and Drug Administration approved the first drug that can relieve depression in hours instead of weeks.

Esketamine, a chemical cousin of the anesthetic and party drug ketamine, represents the first truly new kind of depression drug since Prozac hit the market in 1988.
