Summary

This trial tests whether a shot of ketamine can quickly reduce suicidal thoughts in depressed adults who visit the emergency room. These patients are at high risk of suicide and need fast-acting treatment. Ketamine works by quickly changing brain chemicals to improve mood and reduce suicidal thoughts. It has been found to rapidly reduce depressive symptoms and suicidal thoughts, making it a potential fast-acting treatment for suicidality.

Who is the study for?
This trial is for adults in the emergency department with severe depression and suicidal thoughts who need hospitalization. They must have a certain score indicating suicidality, be experiencing a major depressive episode, and agree to stay in the hospital. It's not for pregnant women, those unable to consent or understand English, people with unstable health conditions like uncontrolled high blood pressure or heart issues, recent substance abuse, psychosis or mania, or intellectual disability.
What is being tested?
The study tests if an injection of ketamine can quickly reduce suicidal thoughts in patients compared to midazolam (a sedative). Participants are given one of these drugs while they're in the emergency room being evaluated for serious mental health concerns.
What are the potential side effects?
Ketamine may cause disorientation, elevated blood pressure, nausea or mood changes shortly after administration. Midazolam can lead to drowsiness, reduced breathing rate and coordination difficulties. Both drugs carry risks that vary based on individual health status.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Intramuscular ketamine is being studied for its rapid relief of suicidal thoughts due to its unique mechanism of action. Ketamine works primarily as an NMDA receptor antagonist, which leads to an increase in glutamate levels and subsequent activation of AMPA receptors. This cascade results in enhanced synaptic plasticity and connectivity, which can rapidly improve mood and reduce suicidal ideation. This rapid action is crucial for suicidal patients who require immediate intervention to prevent self-harm. Other treatments, such as SSRIs and SNRIs, work by increasing serotonin and norepinephrine levels but typically take weeks to show effects, making them less suitable for acute suicidal crises.

I've been blown away by how well Dr. Grunebaum has been able to treat me remotely during the pandemic. I would have thought that telehealth would be a poorer substitute for in-person visits, but I've been pleasantly surprised.
