An increasing amount of research suggests Ketamine in subanaesthetic doses to be an effective antidepressant for Major Depressive Disorder (MDD) and Treatment-Resistant Disorder (TRD). After the finding that NMDA-receptor antagonists may hold antidepressant effect, several studies have suggested Ketamine to have great effect in relief of depressive symptoms. A time lag between biological and behavioural effects have been shown in currently available antidepressants and are not guaranteed to be efficient; only 30% of patients reach adequate response. The aim for this thesis is to systematically review available studies on the efficiency of Ketamine's antidepressant effects in patients with TRD. Scopus, Web of Science, and PubMed were the databases searched for relevant research regarding the subject. Six articles were included in the analysis. A compilation of the results presented a moderate to large effect size for Ketamine compared to placebo at 24 hours through day seven. It is of immense weight that prolonged adverse effects and possible abuse are taken into consideration for future research, as well as how to sustain the dramatic acute antidepressant effect of Ketamine.
