What Is Ketamine and How Does It Work?

Ketamine is a medication that has been used safely in medical settings for decades. At low, sub-anesthetic doses, it has shown benefit for individuals experiencing treatment-resistant depression, PTSD, anxiety, OCD, and related concerns. At New York Integrative Psychiatry, we provide ketamine therapy in NYC within a careful psychiatric framework designed to support safety, clarity, and meaningful therapeutic work.

Unlike standard antidepressants, ketamine works on a different neurotransmitter system involved in forming new neural connections, learning, and cognitive flexibility. This mechanism may allow rigid emotional and cognitive patterns to soften. Many individuals receiving ketamine depression treatment in NYC notice improvements in mood more quickly than with conventional medications—sometimes even after the first session—creating a temporary window of increased neuroplasticity during which psychotherapy can be especially effective.

At our New York ketamine clinic, treatment is provided within a carefully evaluated, clinically guided framework to support both safety and meaningful therapeutic integration.
