Spravato (Esketamine ) Mechanism of Action
Unlike traditional antidepressants (SSRIs or SNRIs) that target monoamines like serotonin, norepinephrine, or dopamine, Spravato works on the glutamate system:
- NMDA Receptor Antagonism: It acts as a non-competitive antagonist of N-methyl-D-aspartate (NMDA) receptors.6
- Neuroplasticity: By blocking these receptors, it is believed to trigger a surge in glutamate, leading to the activation of AMPA receptors. This process promotes “synaptogenesis”—the repair and growth of neural connections in brain regions responsible for mood regulation.
