Standart antidepressants are needed for the many individuals with major depressive disorder. However they do not respond adequately to treatment and because of a delay of weeks before the emergence of therapeutic effects. Recent studies show that subanesthetic dose of ketamine is efficacy and safety for the treatment of depression. Antidepressant effects of ketamine have been found to be short-lived and its psychotomimetic properties may limit the use of ketamine to depressive patients. Future research studies should focus on identifying predictors of response (pharmalogical and clinical) , investigating application of different doses and routes of administration and maintaining antidepressant effect.
