The safety and efficacy of brofaromine, a reversible and selective monoamine oxidase inhibitor, were examined in a multicenter trial of 102 outpatients with social phobia. After a 1-week placebo washout, subjects were randomly assigned to 10 weeks of treatment with either brofaromine (N = 52) or placebo (N = 50). Brofaromine dosage began at 50 mg/day and was titrated to a maximum of 150 mg/day, depending on treatment response. Brofaromine produced a significantly greater change from baseline in Liebowitz Social Anxiety Scale (LSAS) scores compared with placebo, F(1) = 6.01, p < 0.016. Mean LSAS scores decreased from 81.8 at baseline to 62.6 at endpoint for brofaromine, t = 5.41,p < 0.001, and from 79.8 to 70.7 for placebo, t = 3.66, p < 0.001. Eleven of the 14 brofaromine early terminators discontinued because of adverse experiences, as did 4 of the 17 placebo early terminators. Side effects more common with brofaromine than placebo included insomnia, dizziness, dry mouth, anorexia, tinnitus, and tremor. No clinically significant variations in vital signs or laboratory values were found. The findings are consistent with the clinical efficacy for the treatment of social phobia.

Pregabalin is a novel compound in development for the treatment of anxiety disorders. The safety and efficacy of pregabalin for the treatment of social anxiety disorder was evaluated in a double-blind, multicenter clinical trial in which 135 patients were randomized to 10 weeks of double-blind treatment with either pregabalin 150 mg/d. pregabalin 600 mg/d, or placebo. The primary efficacy parameter was change from baseline to end point in the Liebowitz Social Anxiety Scale (LSAS) total score. Safety was assessed through clinical and laboratory monitoring, and recording spontaneously reported adverse events. Ninety-four patients (70%) completed the 11-week double-blind treatment phase. LSAS total score was significantly decreased by pregabalin 600 mg/d treatment compared with placebo (P = 0.024, analysis of covariance). Significant differences (P < or = 0.05) between pregabalin 600 mg/d and placebo were seen on several secondary measures including the LSAS subscales of total fear, total avoidance, social fear, and social avoidance, and the Brief Social Phobia Scale fear subscale. Pregabalin 150 mg/d was not significantly better than placebo on any measures. Somnolence and dizziness were the most frequently occurring adverse events among patients receiving pregabalin 600 mg/d. In conclusion, pregabalin 600 mg/d was an effective and well-tolerated treatment of social anxiety disorder.

The objective of this study was to evaluate the efficacy and tolerability of pregabalin for the treatment of generalized social anxiety disorder (SAD). Patients with generalized SAD, who met the Diagnostic and Statistical Manual of Mental Disorders (fourth edition) criteria (total N=329), were randomly assigned to 11 weeks of double-blind treatment with fixed daily doses of either pregabalin (300, 450, and 600(mg) or placebo. The treatment with pregabalin (600(mg) was associated with a significantly greater mean reduction in the Liebowitz Social Anxiety Scale total score, from baseline to endpoint, compared with placebo (-29.8 vs. -19.7; P= 0.0099), whereas reduction on pregabalin (300(mg, -20.2) and pregabalin (450(mg, -25.5) was not significant Treatment with pregabalin (600(mg) was also associated with a significantly greater improvement than placebo on the fear and avoidance subscales of the Liebowitz Social Anxiety Scale, as well as the majority of other secondary measures. Onset of improvement occurred by week 1 in the pregabalin 600-mg dose group. The most common adverse events on all three doses of pregabalin were somnolence and dizziness. Consistent with a previous study, the results of this study suggest that the 600-mg dose of pregabalin per day may be efficacious in the treatment of SAD.

The objective of this study was to evaluate the efficacy and safety of pregabalin in preventing relapse in generalized social anxiety disorder (SAD). Patients with Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) generalized SAD, who met responder criteria after 10 weeks of open-label treatment with fixed-dose pregabalin (450 mg/day; n=153), were randomly assigned to 26 weeks of double-blind treatment with pregabalin (450 mg/day) or placebo. The primary a-priori outcome of time to relapse was analyzed using the Kaplan-Meier method and the log-rank test. Double-blind treatment with pregabalin was associated with significant delay in time to relapse versus placebo (P=0.035), and with significantly greater maintenance of symptomatic improvement over 26 weeks on the Liebowitz Social Anxiety Scale total (P=0.012) and subscale scores and on the Marks Fear Questionnaire total phobia (P=0.010) and social phobia (P=0.014) subscales. Pregabalin was generally well tolerated. During the double-blind phase, the adverse events that occurred more frequently with pregabalin compared with placebo were dizziness (11.3 vs. 4.1%) and infection (21.3 vs. 16.4%). The results of this study suggest that pregabalin (450 mg/day) is safe, well tolerated, and has significant relapse-prevention efficacy over 26 weeks in patients with SAD who responded to an initial course of the pregabalin treatment.
