Abstract

BACKGROUND: Depression is one of the most common mental disorders. Currently used antidepressants, acting on the monoaminergic system, are insufficient for depression treatment. In recent years, potential application of NMDA receptor modulators in the treatment of drug-resistant depression has gained attention. Administration of ketamine, being a non-competitive NMDA receptor antagonist, contributes to a faster remission of symptoms.
SUBJECTS AND METHODS: The aim of this paper is to review current studies on the use of ketamine in the treatment of drug-resistant depression, compare results of various administration methods - intravenous, intranasal or oral, as well as compare its effectiveness with that of other antidepressants.
RESULTS: Numerous studies show the drug is effective and well tolerated, particularly in patients with increased suicidal thoughts. However, there are concerns on increasing tolerance to the drug and the possibility of implementing a long-term treatment.
CONCLUSION: Oral and intranasal forms of the drug are particularly promising due to their non-invasiveness and ability to self-administer. In March 2019, S-ketamine nasal spray was registered by the FDA for the treatment of drug-resistant depression.
