Enhancing the Therapeutic Efficacy of Sleep Deprivation by Modafinil - Full Text View

Purpose

The study aims to investigate whether the administration of the stimulant modafinil during a 40 hour sleep deprivation period in depressed patients can intensify the antidepressant effect of the sleep deprivation as assessed by a reduction in the Hamilton Depression score (HAMD, 6-item version). We postulate that this also correlates with a reduction of the polysomnographically assessed overall amount of sleep during this period.

Arms	Assigned Interventions
Modafinil (Vigil): Experimental "Modafinil" Arm: during the 40 h sleep deprivation period (morning until evening next day) the depressed patient receives 200 mg of Modafinil each at 12:00, 24:00 and again at 12:00 o' clock	Drug: Modafinil (Vigil) Oral application of 2 x 100 mg Modafinil each encapsulated in identical looking gelatine capsules at 12:00, 24:00 and again at 12:00 o' clock during the 40 h sleep deprivation period
Placebo: Placebo Comparator "Placebo" Arm: during the 40 h sleep deprivation period (morning until evening next day) the depressed patient receives Placebo at 12:00, 24:00 and again at 12:00 o' clock	Drug: Placebo Oral application of 2 x 100 mg Placebo each encapsulated in identical looking gelatine capsules at 12:00, 24:00 and again at 12:00 o' clock during the 40 h sleep deprivation period
