Brief Summary

Biolab Sanus is developing a product in the form of orodispersible tablet containing 1.0 mg, 1.75 mg and 3.5 mg of Zolpidem®. Thus, it is intended to evaluate the efficacy of Zolpidem® Orodispersible 1.0 mg or 1.75 mg in women and Zolpidem Orodispersible 1.75 mg or 3.5 mg in men for the improvement of the maintenance insomnia disorder, through the evaluation of the Insomnia Severity Index, and using a Sleep Diary throughout the study, as well as to evaluate the latency of the sleep after a spontaneous or provoked wake up measured by polysomnography.

Detailed Description

Information provided evidence for the therapeutic use of Zolpidem® in the treatment of insomnia. Several studies have emphasized the importance of using Zolpidem® in small doses, in the orodispersible form, in the treatment of insomnia. Accordingly, Biolab Sanus is developing a product in the form of orodispersible tablet containing 1.0 mg, 1.75 mg and 3.5 mg of Zolpidem®. Thus, it is intended to evaluate the efficacy of Zolpidem® Orodispersible 1.0 mg or 1.75 mg in women and Zolpidem Orodispersible 1.75 mg or 3.5 mg in men for the improvement of the maintenance insomnia disorder, through the evaluation of the Insomnia Severity Index, and using a Sleep Diary throughout the study, as well as to evaluate the latency of the sleep after a spontaneous or provoked wake up measured by polysomnography.

Primary Outcome Measures

Name	Time	Method
Difference Insomnia Severity Index (ISI) as assessed by questionnaire before treatment and after the treatment	28 days	To analyse the efficacy of Zolpidem® Orodispersible treatment 1.0 mg or 1.75 mg in women and 1.75 mg and 3.5 mg in men, compared to placebo, after taking the medication when a spontaneous wake up occurs during 28 days. The assessement will be performed by means of the standard questionnaire before and at the end of the treatment period. The computed mean difference for each treatment will be compared by ANOVA (treatment doses vs placebo in each gender) in order to assess its statistical significance.

Secondary Outcome Measures

Name	Time	Method
Sleep Efficiency (polysomnography parameter)	1 day	Sleep Efficiency after a provoked wake up, and the administration of 1 tablet of Zolpidem® Orodispersible 1.0 mg or 1.75 mg in women and 1.75 mg or 3.5 mg in men, as compared to placebo administration after a provoked wake up.
Sleep Latency (polysomnography parameter)	1 day	Sleep Latency after a provoked wake up, and the administration of 1 tablet of Zolpidem® Orodispersible 1.0 mg or 1.75 mg in women and 1.75 mg or 3.5 mg in men, as compared to placebo administration after a provoked wake up.
Total Sleep Time (polysomnography parameter)	1 day	Total Sleep Time after a provoked wake up, and the administration of 1 tablet of Zolpidem® Orodispersible 1.0 mg or 1.75 mg in women and 1.75 mg or 3.5 mg in men, as compared to placebo administration after a provoked wake up.
