Samelisant's inverse agonism property at the H₃ receptor may be ideal for addressing challenges associated with the constitutive activity. A key distinguishing feature of samelisant is its cleaner drug - drug interaction and cardiovascular safety profile compared to existing treatments. This is particularly important for women of childbearing potential, considering the known interactions of current treatments (e.g. pitolisant and modafinil) with hormonal contraceptives, as well as the common occurrence of polypharmacy and comorbidities in narcolepsy. Additionally, as samelisant may act downstream of orexinergic pathways, it presents an opportunity to complement orexin-based therapies. The potential of samelisant in combination with other narcolepsy treatments represents an important area for future research.
