Is ketamine some sort of wonder-drug for depression? Probably not, at least not according to most of the research conducted on it so far. Like many treatments for depression — including psychotherapy — it appears to change the way the brain processes certain information and effects the connections between neurons. But it’s not clear how long these changes last, or whether chronic ketamine treatment would be needed, similar to a diabetic taking insulin. http://psychcentral.com/blog/archives/2012/12/01/should-you-try-ketamine-for-depression/ http://psychcentral.com/blog/archives/2012/12/01/should-you-... Ketamine has been tested in treatment-resistant bipolar disorder, major depressive disorder, and people in a suicidal crisis in emergency rooms.[26] Benefit is often of a short duration.[27] The quality of the evidence supporting benefit is generally low.[27] The drug is given by a single intravenous infusion at doses less than those used in anesthesia, and preliminary data indicate it produces a rapid (within 2 hours) and relatively sustained (about 1–2 weeks long) reduction in symptoms in some people. https://en.wikipedia.org/wiki/Ketamine#Depression https://en.wikipedia.org/wiki/Ketamine#Depression Ketamine may have its use for treatment resistant depression and dealing with emergencies caused by suicidal bouts because it can make depression symptoms disappear for few days, but this is only temporary as better ketamine based drugs are developed.
