What is Ketamine?

Ketamine is a legal, safe, and effective medicine used to treat a variety of mental health conditions, including depression, anxiety, and PTSD. Ketamine has rapidly-acting antidepressant and mood-enhancing effects, which can begin to take effect within 1-2 hours after treatment. It works by blocking the brain’s NMDA receptors as well as by stimulating AMPA receptors, which are thought to help form new synaptic connections and boost neural circuits that regulate stress and mood. Ketamine has also been shown to enhance overall neuroplasticity for lasting symptom improvement. Ketamine can be administered in a variety of ways, including IV infusion, intramuscular injection, nasal spray, and sublingual lozenges. At Journey Clinical, we only use the sublingual lozenge form.
