Brief summary
The purpose of this study is to evaluate the effect of escitalopram after 8 weeks of treatment in patients with Generalized Anxiety Disorder (GAD), to evaluate proportion of patients who respond to escitalopram during the treatment period, and to evaluate safety of escitalopram.
Detailed description
The study will be performed in Russia, as an open-label, uncontrolled, one arm trial. The patients will receive escitalopram for 8 weeks. Start and maintenance dosages as well as dose titration will be left to the investigators' decision (5 to 20 mg/day), in accordance with the national Summary of Products Characteristics (SPC).
