Ketamine the Next-Gen Treatment
“There are key questions right now concerning both the scientific understanding of ketamine and the potential future use of ketamine or ketamine-like drugs for depression,” Dr Murrough told Medscape Medical News.
One question is how ketamine triggers an antidepressant response within 1 day, whereas conventional antidepressants require 2 weeks or longer to take effect. “What is the biological basis of ketamine’s antidepressant mechanism of action?” he asked.
It also remains a mystery why ketamine is successful in treating symptoms of depression in patients who have not responded to conventional treatments. “What can ketamine do in the brain that is relevant to the treatment of depression, that current antidepressant drugs do not do?” asked Dr Murrough.
