Panic disorder involves recurrent, unexpected panic attacks and persistent concern about future attacks [1]. Panic attack symptoms include:
- A sudden surge of intense fear or discomfort
- Racing heart, shortness of breath
- Dizziness, trembling, chest pain
- Nausea, chills or hot flashes
- Fear of losing control or “going crazy.”
Attacks reach peak intensity within minutes. Those with panic disorder may avoid situations that could trigger an attack.
Ketamine rapidly reduces both panic attacks and generalized anxiety in panic disorder. Studies show it decreases amygdala hyperactivity and improves prefrontal regulation of emotions [2].
In individuals with treatment-resistant panic disorder, a single ketamine infusion led to significantly fewer panic attacks and lower anxiety scores for up to 2 weeks compared to placebo [3].
While more research is needed, ketamine holds promise for quickly interrupting panic and phobia cycles. This could allow the utilization of cognitive-behavioral techniques to sustain improvement long-term [4].
