Mechanism of Action
Esketamine, the S-enantiomer of racemic ketamine, is a non-selective, non-competitive antagonist of the N-methyl-D-aspartate (NMDA) receptor, an ionotropic glutamate receptor. The exact mechanism by which esketamine acts as an antidepressant is unknown. The primary circulating metabolite of esketamine (_noresketamine_) shows activity at the same receptor with a weaker affinity [FDA label].
