MEMPHIS, Tenn. - April 16, 2019 - PRLog -- Today The Journal of Clinical Psychiatry published a systematic review of current literature on the efficacy, safety, tolerability, and dose range of oral ketamine for the treatment of depression.

Depression is the leading cause of disability worldwide, affecting over 350 million people globally. Intravenous ketamine has rapid and robust antidepressant effects; however, poor accessibility of the IV route often limits its use. Numerous alternative routes of administration are being investigated, including intranasal, which has already been approved by the FDA for depression treatment. Oral ketamine is particularly appealing for its ease of use with the potential for high accessibility.

Ketamine is a dissociative anesthetic agent that has been investigated for its antidepressant effects over the past 2 decades. Last month the FDA approved the first ketamine product for treatment of depression: intranasal-administered esketamine, indicating the expanding acceptance of ketamine's use in this capacity, as well as the growing interest in new methods of administion.

The object of the current systematic review is to determine the efficacy, safety, tolerability, and dose range of oral ketamine for depression. Additionally, the authors specifficallyl evaluated the evidence for rapid antidepressant effects, antisuicidal effects, and efficacy in treatment-resistant depression, as these are the effects that IV ketamine differentially provides as compared to conventional antidepressants.
