In a double-blind placebo-controlled trial, ritanserin (a 5-HT2 receptor blocker) 5 mg/day or placebo was added to the usual medication in 28 patients with narcolepsy during 4 wk. The effect was assessed by means of polysomnography, daily and weekly subjective evaluations, and Multiple sleep latency tests (MSLT). During the night ritanserin increased the amount of nonrapid eye movement slow wave sleep and reduced wakefulness after sleep onset. It improved the feeling of being refreshed in the morning after awakening and reduced subjective daytime sleepiness. The drug did not significantly influence sleep latency in the MSLT.
