Sanofi Identifier:
First received: May 7, 2008
Last updated: November 29, 2010
Last verified: November 2010

The primary objective is to compare the potential for next-day residual effects of eplivanserin 5 mg/day and lormetazepam 1 mg/day by measuring the sleepiness in the morning using the patient's sleep questionnaire during 4 weeks of treatment in patients with chronic primary insomnia and sleep maintenance difficulties.

The secondary objectives are to compare the clinical safety of both products, including the potential for rebound insomnia and withdrawal symptoms after treatment discontinuation, to compare the efficacy of both products on subjective sleep parameters and to compare the effects of both products on patient's daytime functioning.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
