Clinical Trials Directory

The purpose of this study is to test the hypothesis that ingestion of the wake-inhibiting drug suvorexant 30 minutes prior to daytime sleep initiation in individuals working overnight shifts will significantly improve both objective (total sleep time, sleep efficiency, wake after sleep onset) and subjective (sleep quality) measures of daytime sleep.

Stanford is now accepting new patients for this trial.
