Esketamine

Esketamine is a medication used to treat depression, particularly when other antidepressants haven't worked. It is a form of ketamine, known for its rapid-acting effects, administered as a nasal spray. Esketamine works by targeting certain brain receptors to quickly improve mood and reduce symptoms of depression. It is usually used alongside other antidepressants and under close medical supervision, as it can cause side effects like dizziness or increased blood pressure. Its fast action offers a valuable option for individuals with severe depression, providing relief within hours or days rather than weeks.
