One of the more interesting depression approaches now is the use of ketamine, an NMDA antagonist. This MoA elicits hallucinations like PCP, but dose is likely critical for the depression indication. It could be that dampening ionotropic or metabotropic glutamate receptors has a beneficial effect in patients with depression." A mechanism with the antidepressant efficacy of ketamine but without the associated adverse effects? Ketamine is a molecule with a long history, starting with its initial development as an…
