[Ketamine for treatment of acute depression].


PMID 24011203

Abstract

In clinical trials a single dose of the N-methyl-D-aspartate (NMDA) receptor antagonist ketamine has shown a rapid antidepressant effect in patients with treatment-resistant depression and bipolar depression. The implications of glutaminergic mechanisms in depression and the rapid effect of a single dose of ketamine could open new pathways to understand the pathophysiology of depression and the development of novel rapid-acting antidepressant drugs.
