Pitolisant: Pediatric First Approval.

Pitolisant (WAKIX®), a histamine H3 receptor antagonist/inverse agonist that has been developed by Bioprojet Pharma, is approved in the EU and USA and elsewhere for use in adults with narcolepsy with or without cataplexy. In February 2023, based on clinical data in patients aged 6 to < 18 years, pitolisant received its first approval in adolescents and children from the age of 6 years for the treatment of narcolepsy with or without cataplexy in the EU. This article summarizes the milestones in the development of pitolisant leading to this pediatric first approval for narcolepsy with or without cataplexy.
