A ketamine-based depression treatment launched seven years ago helped shape a new network of interventional psychiatry clinics across the U.S.
When the treatment first reached market, there were relatively few specialized clinics with the space, staff, and expertise needed to administer it. The environment was described as very underdeveloped and requiring a huge investment.
That early investment appears to have paid off. The treatment generated more than $1 billion in the first half of this year, and thousands of interventional psychiatry clinics now operate across the U.S.
This shift reflects how patient access and clinic capacity can change over time. What stands out most to you about this growth?
