Anxiety disorders are a common, heterogeneous group of illnesses marked by varied clinical presentations, ranging from relatively moderate symptom levels to severe functional impairment and profound disability. Pharmacotherapy, often coupled with behavioral treatments, is a standard approach to treating anxiety disorders. First-line pharmacological treatments for the majority of anxiety disorders are the selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors (1). Sedative-hypnotics are commonly employed for anxiety disorders but are frequently reserved for short durations and targeted symptoms (e.g., insomnia) because of the potential for abuse, dependency, withdrawal reactions, and cognitive impairment (1). The role for antipsychotic drugs in the treatment of anxiety disorders, however, is less clear because of the relative paucity of well-designed trials to assess their safety, efficacy, and effectiveness.
