Trial Summary

What is the purpose of this trial?

The primary objective of this study is to evaluate two pharmacotherapeutic approaches to sleep induction, both of which have been shown to be effective hypnotics, but may have unique side effect profiles. These profiles may have markedly different impacts on performance in a military setting. In this randomized, double-blind, placebo controlled study, the side effects of these drugs will be compared - suvorexant, a dual orexin receptor antagonist and zolpidem, a non-benzodiazepine gamma-aminobutyric acid (GABA) A agonist - in healthy controls comparable in age and gender to the target military population.
