Anticonvulsant drugs have shown promising results in the treatment of mood disorders, leading to the investigation of their potential efficacy in other psychiatric disorders. Numerous case reports, open-label trials, and placebo- controlled trials investigating the use of anticonvulsants in the treatment of anxiety disorders have yielded broad and varying results. Generally, these studies have indicated a potential role for anticonvulsants in the treatment of anxiety as monotherapy or augmentation therapy; however, these early findings must be supported by additional investigation in large-scale, placebo-controlled studies. This article reviews past and current research being done in this novel area of psychopharmacology.
