Esketamine is a NMDA receptor antagonist used for treatment-resistant depression.
Esketamine is a NMDA receptor antagonist used for treatment-resistant depression.
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.
Esketamine is indicated in combination with an oral antidepressant for the treatment of treatment-resistant depression in adults. It is also indicated for the treatment of depressive symptoms in adults with major depressive disorder experiencing acute suicidal ideation or behaviour.
