A systematic review by the Canadian Network for Mood and Anxiety Treatments evaluated evidence for racemic ketamine in treatment-resistant depression. Single intravenous infusions have Level 1 evidence for efficacy in adults, while multiple or maintenance infusions have only Level 3 evidence. Adverse events include dissociative symptoms and hypertension. Non-IV formulations have Level 3 or 4 evidence. Single-dose IV racemic ketamine is a third-line recommendation; repeated use requires careful case-by-case risk-benefit assessment. Oral and other formulations should be limited to specialists with ketamine expertise at tertiary centers due to limited evidence and risk of misuse.
