Anxiety is a mental health condition characterized by excessive worry, fear, and heightened nervousness. It can manifest in various forms, such as generalized anxiety disorder (GAD), social anxiety disorder, panic disorder, and others. Anxiety disorders can significantly impact daily functioning and quality of life.

Ketamine, traditionally known as an anesthetic and analgesic, has gained attention in recent years as a potential treatment for various mental health conditions, including anxiety disorders. Similar to its potential role in depression treatment, ketamine may also have anxiolytic (anti-anxiety) effects.

The mechanism by which ketamine may alleviate anxiety is not fully understood, but it is thought to involve the modulation of glutamate, the major excitatory neurotransmitter in the brain. Ketamine's impact on the glutamate system is believed to contribute to its rapid antidepressant and anxiolytic effects.

Several studies have explored ketamine's potential in treating anxiety disorders, and some have shown promising results. Like with depression, ketamine's effects on anxiety can occur quickly, often within hours to days after administration. However, similar to its use in depression, the effects of ketamine on anxiety may be temporary, necessitating repeated doses to maintain benefits.
