Repeated Ketamine Infusions Reduce Symptoms in PTSD Patients

Repeated intravenous (IV) ketamine infusions significantly reduce symptom severity in individuals with chronic post-traumatic stress disorder (PTSD) and the improvement is rapid and maintained for several weeks afterwards, according to a study conducted by researchers from the Icahn School of Medicine at Mount Sinai. The study, published January 5 in the American Journal of Psychiatry, is the first randomized, controlled trial of repeated ketamine administration for chronic PTSD and suggests this may be a promising treatment for PTSD patients.
