Dual orexin receptor antagonist (DORA) (3) · PDE5 Inhibitor (1) · Selective 5HT2A inverse agonist (with weaker 5HT2C inverse agonism) (1) · the first approved (1) · [[:Category:Antifungals|Antifungal (triazole)]] (1) · [[:Category:Azalides|Azalide]] (1) · [[:Category:Macrolide_antibiotics|Macrolide antibiotic]] (1) · [[:Category:Triazoles|Triazole]] (1)

None (3) · Competitive antagonist at OX1R and OX2R. Faster receptor association/dissociation kinetics than suvorexant (~16 sec dissociation vs ~57 sec) hypothesized to support sleep onset, with sufficient duration for maintenance. (1) · Competitive antagonist at OX1R and OX2R. First-in-class DORA. Receptor dissociation slower than lemborexant or daridorexant. (1) · Selective inhibitor of PDE5. Slightly higher PDE5/PDE6 selectivity vs sildenafil (less visual side effect) but more PDE1 cross-activity (occasional QT effects at high doses). (1) · Selective inverse agonist at 5HT2A receptors with weaker activity at 5HT2C. Has no significant dopamine D2 affinity, unique among approved antipsychotics. Inverse agonism (rather than antagonism) reduces constitutive 5HT2A receptor activity below baseline. (1)
