Low dose IV Ketamine vs. IN Esketamine
DrugFor IV ketamine treatment, ketamine is administered at 0.5mg/kg over 40 minutes.

All treatments are administered at the academic center under the supervision of a mental health care professional. Patients are asked to come fasting at least two hours prior to treatment and to remain resting in the treatment room throughout the dosing session. Throughout each dosing session, blood pressure, oxygen levels, and onset, duration and severity of common side effects are recorded by nursing staff and/or physicians. Patients are discharged after a minimum of 30 minutes post administration, provided that the vital signs return to baseline and that the patient is calm, alert, and oriented.
