Treatment of cocaine-induced panic disorder

The authors describe 10 patients who developed panic attacks only after substantial cocaine use. The timing of the onset of symptoms, i.e., after 1-6 years of cocaine use, and the fact that only one patient had a first-degree relative with panic disorder were more suggestive of acquired than primary panic disorder. The patients' atypical symptoms and responses to medications may be explained in terms of limbic-neuronal hyperexcitability induced by cocaine through a kindling mechanism.
