In recent years, Pitolisant has emerged as a potential treatment for narcolepsy, a chronic neurological disorder characterized by excessive daytime sleepiness and disrupted sleep-wake cycles. The drug works by enhancing the activity of histamine in the brain, promoting wakefulness and reducing sleepiness. While Pitolisant has gained attention for its efficacy in narcolepsy treatment, its FDA approval and availability may vary depending on the type of narcolepsy and the country in question.
Pitolisant and FDA Approval
The United States Food and Drug Administration (FDA) has indeed approved the use of Pitolisant for the treatment of excessive daytime sleepiness (EDS) in adult patients with narcolepsy. It is important to note that this approval specifically applies to narcolepsy type 1 (narcolepsy with cataplexy), which is characterized by a sudden loss of muscle tone triggered by strong emotions.
For narcolepsy type 2 (narcolepsy without cataplexy), the FDA is yet to approve Pitolisant. However, the drug may still be prescribed off-label in some cases, with the physician's discretion.

Pitolisant and its Impact on Treatment
Pitolisant has shown promising results in the treatment of narcolepsy, particularly in reducing excessive daytime sleepiness and improving overall wakefulness. Clinical trials have demonstrated its efficacy in increasing the mean sleep latency during the daytime and reducing the frequency of cataplexy attacks in narcolepsy type 1 patients.
Despite its potential benefits, it is important to consider any possible side effects and drug interactions. Some common side effects of Pitolisant include headache, insomnia, nausea, anxiety, and increased heart rate.
