Ketamine—New Possibilities in the Treatment of Depression: A Narrative Review

The SARS-CoV-2 epidemic has increased the number of people experiencing depression, with about one third of the global population affected by mental health symptoms such as depression and anxiety. S-ketamine, approved by the FDA in March 2019 for drug-resistant depression, offers a rapid antidepressant effect, reaching maximum effectiveness within 24 hours and possibly reducing suicidal thoughts. However, further research on its side effects is needed, particularly for individuals prone to psychosis or those using alcohol or psychoactive substances.

Abstract

The SARS-CoV-2 coronavirus epidemic has led to an increase in the number of people with depression. Symptoms related to the mental sphere (mainly depression and anxiety) may be experienced by one third of the worldwide population. This entails the need for the effective and rapid treatment of depressive episodes. An effective drug seems to be s-ketamine, which was accepted in March 2019 by the Food and Drug Administration (FDA) for the treatment of drug-resistant depression. This drug provides a quick antidepressant effect with maximum effectiveness achieved after 24 h. It also appears to reduce the occurrence of suicidal thoughts. However, research into undesirable effects, especially in groups of people susceptible to psychotic episodes or those who use alcohol or psychoactive substances, is necessary.
