Open-label tiagabine monotherapy for major depressive disorder with anxiety.

OBJECTIVE: Gamma-aminobutyric acid (GABA) plays a key role in the pathophysiology and treatment of depression and anxiety. Tiagabine, a selective GABA reuptake inhibitor (SGRI) that enhances normal GABA tone, was evaluated for its efficacy and safety in the treatment of depression comorbid with significant anxiety. METHOD: In this 8-week, single-center, open-label study, adults with DSM-IV-diagnosed major depressive disorder and significant anxiety (i.e., "anxious depression") received tiagabine monotherapy, initiated at 4 mg/day and titrated for optimum response as tolerated to a maximum dose of 20 mg/day. Symptoms, function, and adverse events were assessed at regular intervals. Patients were entered from April 2002 to February 2003. RESULTS: Nineteen patients entered the study and 15 met criteria for intent-to-treat analyses. Of those, 6 (40%) discontinued treatment and 9 (60%) completed the 8-week protocol. Tiagabine significantly improved depression, as shown by a reduction in mean +/- SD Hamilton Rating Scale for Depression scores from baseline (31.9 +/- 6.1) to endpoint (17.0 +/- 12.4; p = .002). Categorical response rate was 47% (N = 7). Tiagabine also significantly improved anxiety (Hamilton Rating Scale for Anxiety baseline score of 22.7 +/- 4.9 vs. endpoint score of 12.5 +/- 8.8; p = .002). The mean +/- SD final daily dose was 12.8 +/- 5.8 mg. The most commonly reported adverse events were dizziness, headache, and gastrointestinal upset/nausea. CONCLUSION: These results suggest the potential of the SGRI tiagabine in the treatment of depression with anxiety. Large, placebo-controlled trials are needed.[1]
