Pitolisant (INN) or tiprolisant (USAN) is a histamine receptor inverse agonist/antagonist selective for the H3 subtype.[1] It has stimulant and nootropic effects in animal studies,[2] and may have several medical applications, having been researched for the treatment of narcolepsy, for which it has been granted orphan drug status in the EU and US.[3][4] It is currently in clinical trials for schizophrenia and Parkinson's disease.[4][5][6]

Pitolisant was developed by Jean-Charles Schwartz and colleagues after the former discovered H3 receptors.[7] Pitolisant was the first clinically used H3 receptor inverse agonist.
