Ketamine in the Treatment of Suicidal Depression
This study is designed to compare the effectiveness of two medications, Ketamine and Midazolam, for rapidly relieving suicidal thoughts in people suffering from depression.
Detailed Description
Randomised, double-blind, parallel-group trial in depressed adults with suicidal ideation comparing a single IV infusion of ketamine (0.5 mg/kg) versus midazolam (0.02 mg/kg); infusions administered over ~40 minutes.
Nonresponders who received midazolam may be offered a second ketamine infusion; participants receive weekly follow-up interviews for 6 weeks and may be offered standard antidepressant treatment thereafter. Study requires brief inpatient admission at NYSPI.
