A comparison of Zolpidem Tartrate Extended-Release (Ambien CR)vs. Placebo in the Treatment of Insomnia Associated with Generalized Anxiety Disorder (GAD) when Used Concomitantly with Escitalopram (Lexapro - antidepressant).
Drug: zolpidem tartrate
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
Primary Outcome Measures:
- Evaluate safety and hypnotic efficacy of zolpidem tartrate extended release vs. placebo in treatment of insomnia associated with Generalized Anxiety Disorder when used concomitantly with escitalopram
Secondary Outcome Measures:
- To show that treating insomnia from beginning of SSRI (Selective Serotonin Reuptake Inhibitor) treatment for anxiety results in improvement in quality of life and possibly greater response to anti-anxiety therapy
