Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of the study is to examine the role of paroxetine, an antidepressant medication, in the acute and continuation treatment of insomnia. Primary insomnia is a type of insomnia not directly resulting from general medical, chemical, or psychiatric conditions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary aim of this study is to demonstrate the role of paroxetine in the acute treatment of chronic primary insomnia. Paroxetine taken on a nightly basis in combination with sleep hygiene therapy will produce a greater number of diagnostic responders in acute treatment, compared to a placebo and sleep hygiene control condition, in a randomized, double-blinded, six-week acute treatment trial. EEG sleep, sleep quality, and daytime well-being, and daytime functioning will also show superior treatment effects during acute treatment with paroxetine plus sleep hygiene, as compared with the placebo control condition.

A total of 66 patients with primary insomnia, as defined by DSM-IV criteria, will be randomized (1:1) to receive paroxetine plus sleep hygiene therapy (P+SH-a) or placebo plus sleep hygiene therapy (PL+SH-a) in weekly acute treatment sessions evolving over a six-week interval in a double-blinded, parallel group design.
