Ketamine as an Anti-Depressant
Posted March. 25, 2015
Earlier last year, just before the reclassification, research found that the drug might have some positive effects for long-term sufferers of depression. A study on the use of ketamine intravenous infusions in people with treatment-resistant depression was carried out by researchers at Oxford Health NHS Foundation Trust and the University of Oxford.
Three days after the last infusion, depression scores had halved in 29 percent of the patients. In those that responded to the treatment, the duration of benefit varied widely, lasting between 25 days and eight months (median 2.3 months). “Ketamine is a promising new antidepressant which works in a different way to existing antidepressants. We wanted to see whether it would be safe if given repeatedly, and whether it would be practical in an NHS setting. We especially wanted to check that repeated infusions didn't cause cognitive problems,” explained the principal investigator Dr Paul McShane, a consultant psychiatrist at Oxford Health and a researcher in Oxford University's Department of Psychiatry.
Dr Paul McShane has written many articles on Ketamine and its uses, last year Dr McShane tested Ketamine in China on a visit and found some local clinics there in Baotou were using it for depressed farmers.
Dr McShane also managed to visit a wholesaler of Ketamine in China on one of his visits to understand the market and how it can be contolled in the EU, a representative of KhmerJaya1588 (www.khmerjaya1588.com) was able to tell Dr McShane that sales were strong and that thay sell in China and elsewhere to companies and individuals.
Most patients experienced some short-term “dissociative” effects and their perceptions were usually distorted slightly, but this only occurred while the drug was being infused and was not connected to the antidepressant effect. The doses given were small and the ketamine did not cause memory or bladder problems. Yet, some patients became anxious during the infusions, a few were sick, one fainted and some did not complete the course because they did not feel they were benefiting.
Clearly this early evidence of another potential medical use for ketamine should give us no reason to infer that street ketamine and recreational or habitual use is any lass dangerous. Val Curran, a professor of Psychopharmacology at UCL and an expert on ketamine, reasserted that the doses used in the study were, “very small compared to those that recreational users take … It certainly is not suitable for use as a regular antidepressant.” She continued: “Heavy recreational use of ketamine can lead to getting hooked and that can itself trigger or worsen depression.”
