Experimental Antidepressant Use
According to a National Institute of Mental Health press release on 7 August 2006, a study of 17 patients led by Dr Carlos Zarate Jr. of the NIMH showed that ketamine significantly improved treatment-resistant major depression within two hours of injection. The improvement lasted up to one week after the single dose. The patients in the study were previously treatment resistant, having tried an average of six other treatments that failed. The importance of these findings was articulated by NIMH director Dr Thomas Insel: “This is the first report of any medication or other treatment that results in such a pronounced, rapid, prolonged response.” The researchers apparently attribute the effect to ketamine being an NMDA receptor antagonist.
The study appears in the Archives of General Psychiatry.
