Pharmacologic Treatments for Anxiety

Abstract

While the public health perspective prioritizes large populations of affected individuals, our job as clinicians is to help one patient at a time. Over the last 10–20 years, there has been marked improvement in pharmacologic and psychosocial interventions available for patients with anxiety disorders (Slide 8).The use of antidepressants, particularly the serotonergic and serotonergic noradrenergic agents, have received increased attention as first-line treatment for most of the anxiety disorders, including panic disorder, social phobia, posttraumatic stress disorder (PTSD), and generalized anxiety disorder (GAD). Antidepressants are often used as first-line therapy for anxiety disorders because of their broad spectrum of efficacy against common comorbidities, especially depression, and because of concern about benzodiazepine-associated dependence, abuse liability, and lack of efficacy for depression and other comorbidities (Slide 9).These newer antidepressants have advantages over the older antidepressants, particularly the tricyclics and the monoamine oxidase inhibitors, in that they are generally better tolerated and more appropriate for use in potentially suicidal patients because they are less lethal in overdose. However, there are some side effects that may limit their use in some patients. In the case of the serotonergic antidepressants, many patients are hesitant to initiate or maintain treatment due to concerns about sexual dysfunction.
