A Multicenter, Open-label Study to Determine the Effects of Lacosamide on Sleep in Healthy Subjects

The effects of Lacosamide, an antiepileptic drug, on sleep have not been formally evaluated. The present study is being conducted to assess the effects of Lacosamide on sleep quality in healthy subjects.

In some patients with Epilepsy, seizure activity is associated with specific phases of sleep/wake cycle, and sleep deprivation is known to precipitate seizure activity. Inadequate or disturbed sleep and excessive daytime drowsiness is often reported by patients with Epilepsy due to the effects of seizures as well as antiepileptic drugs. Thus, the use of healthy subjects improves the certainty that any changes in sleep are related to the study drug and not other factors.
