Pitolisant


Pitolisant is used to treat excessive daytime sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness) and to treat cataplexy (episodes of muscle weakness that begin suddenly and last for a short time) in adults with narcolepsy. Pitolisant is in a class of medications called H3 blockers. It works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.
