Brief Summary

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

The purpose of this study is to determine the dose response of Ramelteon, once daily (QD), in Japanese subjects with Chronic Insomnia

Detailed Description

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

Complaints of sleep disorder are increasing with today's aging society and changing lifestyle. Sleep disorders not only impact one's activities of daily living, but also impede one's social life, leading to reduced productivity and sometimes accidents through carelessness.

Ramelteon is a melatonin-1 receptor agonist under global development by Takeda Chemical Industries, Ltd., Osaka, Japan, for the treatment of transient and chronic insomnia and for the treatment of Circadian Rhythm Sleep Disorders.
