How does Ketamine Infusion Therapy work?
Ketamine works by blocking the NMDA (N-methyl-D-aspartate) receptor, one of three major glutamate receptors. This receptor is involved in synaptic plasticity and memory function, among other functions. A ketamine-induced blockade of the NMDA receptor results in an increase in glutamate. This initiates a cascade of neurobiological events that researchers believe is a key reason behind ketamine’s rapid antidepressant effects.
