Clinical experience with paroxetine in social anxiety disorder

Paroxetine is a selective serotonin reuptake inhibitor (SSRI) with proven efficacy in the treatment of depression, panic disorder and obsessive-compulsive disorder. Evidence that paroxetine may be effective in social anxiety disorder (social phobia) first arose from open-label studies. More recently, three multicentre, randomized, placebo-controlled trials have been performed, each lasting 12 weeks, to assess the efficacy and tolerability of paroxetine in the treatment of social anxiety disorder, and these studies are reviewed here. The data from all three studies consistently demonstrated that paroxetine was effective in reducing both the symptoms of anxiety and the disability and impairment of social anxiety disorder. Paroxetine performed significantly better than placebo on all primary (Liebowitz Social Anxiety Scale, Clinical Global Impression) and secondary (Social Avoidance and Distress Scale, Sheehan Disability Scale) outcome measures. Adverse events were restricted to those already known to be associated with SSRIs, no serious adverse events associated with medication were experienced, and the numbers withdrawing from the studies were not significantly different in the paroxetine and control groups. Taken together, these studies confirm that paroxetine is an effective and well tolerated treatment for patients with social anxiety disorder.
