Sleep Loss and Mechanisms of Impaired Glucose Metabolism

Completed · Not applicable · Has a placebo group

Conditions studied: Primary Insomnia

In brief

The purpose of this study is to test the effects of sleep and eszopiclone, a drug that helps people sleep, on how the body processes glucose (sugar). Eszopiclone is approved by the U.S. Food and Drug Administration (FDA) for sale for the treatment of insomnia. It is marketed in the United States as LUNESTA.
