In this phase 3 randomised double‑blind trial, adequately dosed subcutaneous racemic ketamine given twice weekly for 4 weeks produced significantly higher remission than midazolam in the flexible‑dose cohort (19.6% v. 2.0%; OR 12.1, 95% CI 2.1–69.2, P = 0.005) but not in the fixed‑dose cohort. Ketamine was well tolerated with transient adverse effects resolving within two hours, supporting the subcutaneous route as a practical option for treatment‑resistant depression.
