How quickly does Esketamine typically work to relieve depression symptoms?

Esketamine is known for its rapid onset of action in treating depression, particularly treatment-resistant depression. The unique mechanism of action for Esketamine, which is a derivative of ketamine, allows it to affect brain chemistry more quickly than traditional antidepressants that often take weeks to show effects. Patients may begin to notice a reduction in symptoms within hours of administration, making it a significant option for those who require immediate relief. This rapid effectiveness is one of the reasons Esketamine has gained attention in recent years for managing severe and urgent depressive symptoms, particularly in cases where immediate action is necessary.
