Pitolisant

Introduction: What is Pitolisant?

Pitolisant is a medication primarily used to treat excessive daytime sleepiness associated with narcolepsy, a chronic sleep disorder characterised by overwhelming daytime drowsiness and sudden sleep attacks. Approved by the FDA in 2019, pitolisant is a wakefulness-promoting agent that is distinct from traditional stimulant medications as it does not carry the same risk of dependency or stimulant-related side effects. Marketed under the brand name Wakix, it helps people regain control over their daily activities by reducing sleepiness.

Uses of Pitolisant

Pitolisant is primarily indicated for the treatment of narcolepsy in adults. It is effective in managing symptoms such as excessive daytime sleepiness and cataplexy (sudden muscle weakness from emotions), which is a sudden loss of muscle tone triggered by strong emotions. While its primary use is narcolepsy, ongoing research is exploring its potential benefits for other sleep disorders and conditions characterised by excessive sleepiness.

How does Pitolisant work?

Pitolisant works by modulating the activity of certain neurotransmitters in the brain, particularly histamine. It increases the release of histamine, which plays a crucial role in promoting wakefulness and alertness. By enhancing histaminergic activity (works by increasing a natural brain chemical that helps you stay awake), pitolisant helps to reduce sleepiness and improve overall wakefulness without the stimulant side effects commonly associated with traditional medications.

Doziranje i primjena

The standard dosage of pitolisant for adults typically starts at 8.9 mg once daily, taken in the morning. Depending on the patient's response and tolerability, the dose may be increased to a maximum of 18 mg per day. For pediatric patients aged 6 years and older, the dosage is determined based on body weight, starting at 4.5 mg and can be adjusted accordingly. Pitolisant is available in tablet form and should be taken orally, with or without food.
