Figure.. Estimated Differences of Groups Treated With Intravenous Ketamine or Intranasal Esketamine
Patients received intravenous (IV) ketamine (0.5 mg/kg over 40 minutes) or intranasal (IN) esketamine (56 or 84 mg) to treat depression. Their depression trajectories were assessed using scores on the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR).
