A Double-Blind Comparative Study of Brofaromine and Fluvoxamine in Outpatients With Panic Disorder

Abstract

Previous studies have shown that both selective serotonin reuptake inhibitors (SSRIs) and monoamine oxidase inhibitors (MAOIs) are effective in the treatment of panic disorders (PD). In this study, the SSRI fluvoxamine (Fluv) was compared with the MAO-A-I brofaromine (Brof). Thirty patients with the diagnosis of PD with or without agoraphobia were treated with either Fluv or Brof (150 mg daily) in a double-blind design. After 12 weeks of treatment, 93% of the Brof group and 87% of the Fluv group considered themselves much or very much improved. Taking a reduction in the Hamilton Rating Scale for Anxiety score of 50% or more, 33% of the Fluv patients and 47% of the Brof patients were responders to treatment. After an increase in anxiety in the 1st week, which was more severe in Fluv-treated patients than for Brof, a clinically relevant decrease in anxiety symptoms and reduction in panic attacks and avoidance behavior was observed. There was no significant difference between the treatment groups. The most prominent side effects were middle-sleep disturbance (Brof), tiredness (Fluv), and nausea after taking the medication (Brof and Fluv). During a double-blind follow-up period of another 12 weeks, a further improvement was found in both treatment groups without significant differences between the two groups. The selective and reversible MAO-A-I brofaromine and the SSRI fluvoxamine are equally effective in the treatment of PD. Both compounds lead to a reduction in the number of panic attacks and a subsequent reduction in agoraphobic avoidance.
