Existing drugs to treat major depression which is resistent to other forms of treatment take weeks to kick in. In the meantime, many patients end up dead from suicide or other depression related causes.
A new IV drug, called ketamine, in contrast, starts to mitigate major depression in about two hours and can last a week, according to an early stage double blind human trial involving 17 patients with major depression. Of the trial patients, 12 were helped by and 5 were temporarily cured by the drug. Six were still benefiting a week after receiving the drug.
