Abstract:Objective: To investigate the long-term efficacy, prevention of relapse and safety of sertraline in the treatment of panic disorder.
Method: This study consisted of 52 weeks of open-label sertraline treatment (n=398) followed by a 28 weeks of a double-blind, placebo-controlled discontinuation trial (n=183).
Results: Ninety-three patients were randomized to sertraline and 90 were randomized to placebo. Discontinuation due to insufficient clinical response occurred in 23.6% of placebo-treated patients and 12.0% of sertraline-treated patients (log-rank test, P=0.040). Thirty-three per cent of placebo-treated patients had an exacerbation of panic symptomatology, versus 13% of sertraline-treated patients (log-rank test, P=0.005). Abrupt cessation of sertraline resulted in dizziness (4.3% sertraline vs. 16.9% placebo; P=0.007) and insomnia (4.3% sertraline vs. 15.7% placebo; P=0.013) occurring at significantly higher rates.
Conclusion: Long-term sertraline treatment was effective in preventing relapse of panic disorder, well tolerated and associated with minimal discontinuation symptoms.
