Abstract

In the absence of head-to-head studies directly comparing the efficacy of intranasal esketamine to that of intravenous ketamine, valid conclusions regarding comparative efficacy cannot be made based on the existing data from trials using markedly differing study designs and patient populations.

Keywords: Depression; Esketamine; Ketamine; Major depressive disorder.
