The discovery of ketamine’s therapeutic potential for psychiatric disorders changed the field of mental health, since nearly every FDA-approved medication for schizophrenia and mood disorders targeted monoamine signaling, i.e., dopamine, serotonin, and norepinephrine. As ketamine was initially used as an anaesthetic, ketamine’s ability to modulate monoamine signaling pathways emerged, leading to ground-breaking breakthroughs. In this touchNEUROLOGY interview, we speak with Dr John Krystal (Yale University, New Haven, CT, USA) to briefly discuss ketamine’s discovery for treating psychiatric disorders.

Transcript
How did the discovery of ketamine’s rapid antidepressant effects challenge the traditional approach to treating psychiatric disorders targeting monoamine signaling?

Ketamine was really quite a surprising and in some ways shocking discovery. Until ketamine, we were used to antidepressants that targeted monoamine signalling in the brain and that often took several months of treatment in order to have their full effects. When we first gave ketamine to depressed patients in the mid 90s, we were shocked and surprised to see how rapidly people responded. Some people began to feel better within a few hours, and many people felt completely better within 24 hours of their first dose. This was surprising to us. It was equally surprising and hard to believe for the field, and it’s taken many years and many replications to make a very compelling case for people that ketamine really is so rapidly effective and so effective for many patients who have failed to respond to other treatments for their depression.
