Background
Intravenous Ketamine has shown robust antidepressant efficacy although other routes of administration are currently needed. We conducted a systematic review and meta-analysis of studies evaluating the efficacy and tolerability of oral ketamine for depression.
Methods
A comprehensive search of major electronic databases from inception to April 2020 was performed. Studies of oral ketamine for depression, from case series to randomized clinical trials, were eligible. Randomized controlled trials were included in a meta-analysis, focusing on response, remission, time to effect, and side effects.
Results
A total of 917 articles were identified with 890 studies screened, yielding a total of 10 studies included in our systematic review.Three randomized controlled trials (RCTs) (N = 161, mean age 37.9 ± 9.5 years, 58.6% females) were included in the meta-analysis. Pooled analysis suggested a significant antidepressant effect of oral ketamine (SMD: -0.75; 95% CI: -1.08, -0.43; p<0.0001; I
Conclusion
This focused meta-analysis of oral ketamine suggests a marginal efficacy for major depressive disorder without increased risk of adverse events. Further larger sample studies are needed to confirm these preliminary findings, analyzing differential response/remission rates by affective disorder, optimal dosing strategies, and its long-term effects.
