About Antidepressant NMDA Receptor Antagonists.

While the exact phrase "Antidepressant NMDA Receptor Antagonists" is a functional grouping rather than a formal, standalone Established Pharmacologic Class designation by regulatory agencies, it describes a modern class of psychotropic medications that modulate glutamatergic signaling to treat mood disorders.

These agents exert their therapeutic effect primarily by noncompetitively or uncompetitively blocking N-methyl-D-aspartate (NMDA) receptors, which triggers downstream synaptic plasticity, enhances AMPA receptor activation, and promotes neurotrophic signaling.

Clinically, members of this therapeutic category—such as esketamine and dextromethorphan in combination regimens—are indicated for major depressive disorder and treatment-resistant depression, offering a rapid-acting alternative to conventional monoaminergic antidepressants.
