Dose-related effects of ketamine for antidepressant-resistant symptoms of posttraumatic stress disorder in veterans and active-duty military: a double-blind, randomized, placebo-controlled multi-center clinical trial.

ketamine vs antidepressant

Highlights: The standard ketamine dose-treated depression significantly more than placebo. Ketamine produced dose-related dissociative and psychotomimetic effects, which returned to baseline within 2 h and were less pronounced with repeated administration. Involved 158 veterans and service members with treatment-resistant PTSD that failed prior antidepressant treatments in the past. Veterans were divided into a placebo group, and […]
