Ketamine treats depression in hours

Ketamine proved effective in under two hours. An anaesthetic can treat depression within hours, a study has suggested. A US team found ketamine, a medication usually used as an anaesthetic but also taken as a recreational drug, relieved symptoms of depression. Most existing treatments for depression take weeks or even months to relieve people's symptoms. But the team, writing in Archives of General Psychiatry, said ketamine would need to be altered so it lost its existing hallucinatory side-effects.
