Pitolisant oxalate is primarily used in the treatment of narcolepsy, a chronic sleep disorder characterized by excessive daytime sleepiness and sudden episodes of muscle weakness (cataplexy). It works by enhancing the activity of histamine in the brain, which promotes wakefulness and alertness. This medication is particularly beneficial for patients who do not respond well to traditional stimulants or who experience side effects from other treatments. Additionally, pitolisant oxalate has shown promise in improving cognitive function and reducing fatigue in individuals with other conditions such as obstructive sleep apnea and Parkinson’s disease. Its unique mechanism of action makes it a valuable option for managing sleep-related disorders while minimizing the risk of dependency or abuse.
