The need for speed: A new approach to treating depressive disorders



Current therapies for depressive disorders take many weeks to work, during which time the symptoms of depression, including suicidal thinking, persist and can be fatal. Patients need better treatments that begin relieving symptoms immediately.


IRP researchers led by Carlos A. Zarate, M.D., took a novel approach to the problem and discovered that a single infusion of ketamine provides a fast, robust, and sustained antidepressant effect, including reduction of suicidal thoughts within minutes.


Having demonstrated unprecedented speed of symptom relief, ketamine and its analogs are now being tested in clinical trials around the world and, if approved for use, could become a new standard of care for treating people with depressive disorders.
