Notable for being '''not a controlled substance''' unique among approved wake-promoting medicines, all of which have abuse potential and DEA scheduling (modafinil IV, methylphenidate II, amphetamine II, solriamfetol IV, sodium oxybate III).

Mechanism: H3 autoreceptors on histamine neurons in the tuberomammillary nucleus normally inhibit histamine release. Pitolisant blocks (or inverse-agonizes) these autoreceptors, disinhibiting histamine release and promoting wakefulness. Downstream effects on acetylcholine, norepinephrine, and dopamine pathways may also contribute. Slow titration required.
