In the non-acute, outpatient setting, patients screened for general anxiety disorders benefit from behavioral therapy and initiating an agent from which class of drugs?

Generalized anxiety disorder (GAD) is a chronic mental health condition characterized by excessive, persistent worry and associated physical symptoms such as restlessness, muscle tension, and sleep disturbance. Outpatient management typically involves a combination of psychotherapy, especially cognitive behavioral therapy, and pharmacologic treatment. First-line medications are chosen for long-term safety, effectiveness, and low risk of dependence. Treatment aims to reduce anxiety symptoms while improving daily functioning over time. Rationale: A. Barbiturates are not used for generalized anxiety disorder due to their high risk of sedation, respiratory depression, tolerance, and dependence. They have a narrow therapeutic index and are associated with significant overdose risk. For these reasons, they are no longer recommended for outpatient management of anxiety disorders. B. Benzodiazepines may provide short-term relief of anxiety symptoms, but they are not first-line for long-term outpatient treatment due to risks of dependence, tolerance, and withdrawal. While they may be used temporarily during acute exacerbations, they do not address the underlying chronic nature of GAD and are not preferred for routine maintenance therapy. C. Atypical antipsychotics are not first-line treatments for generalized anxiety disorder. Although some may be used as adjuncts in treatment-resistant cases, they carry risks such as weight gain, metabolic syndrome, and extrapyramidal symptoms. Their risk profile outweighs their benefit in routine outpatient anxiety management. D. Selective serotonin reuptake inhibitors (SSRIs) are first-line pharmacologic agents for generalized anxiety disorder because they improve serotonin availability, reducing chronic anxiety symptoms over time. SSRIs are effective for long-term management, have a favorable safety profile, and are not associated with dependence. When combined with behavioral therapy, they provide the most evidence-based outpatient treatment approach for GAD.
