The Effect of Caffeine on the Narcoleptic Patients Randomized Controlled Clinical Trial
In Brief
A Phase 2 clinical trial evaluating Vivarin and Fiber for Narcolepsy. Completed, enrolled 16 participants across 1 site.
Detailed Summary
Caffeine may be playing a beneficial role in patients with narcolepsy. However, the relationship between caffeine and its effects on narcoleptic patients has not been examined, and it is also unclear whether caffeine provides a beneficial effect or not. Hence, the aim of this study is to assess the effects of caffeine consumption on daytime sleepiness and reaction time in narcoleptic patients.

Timeline
Interventions
Adenosine is an endogenous sleep-promoting substance with neuronal inhibitory effects. Adenosine has been proposed to be a sleep-inducing substance accumulating in the brain during prolonged wakefulness. Caffeine is an adenosine receptor antagonist. It inhibits a part of the sleep cycle and, in turn, promotes the wakeup state. Caffeine results in the release of norepinephrine, dopamine and serotonin in the brain and the increase of circulating catecholamines, consistent with reversal of the inhibitory effect of adenosine.Vivarin Drug class :Central nervous system (CNS) stimulants.
Fiber will be used as placebo.
