N-methyl-D-aspartate receptors (NMDARs) are involved in the pathophysiology of depression and are inhibited by many antidepressants. In this work, we studied the action of the vortioxetine, a relatively new multitarget antidepressant, on native NMDARs in rat hippocampal CA1 pyramidal neurons and compared it to the action of structurally similar antidepressant fluoxetine. Vortioxetine inhibited these receptors with IC
