mechanism:
None (1) ·
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) ·
Dopamine D2 and serotonin 5-HT2A receptor antagonist'"`UNIQ--ref-0000008D-QINU`"' '"`UNIQ--vote-0000008E-QINU`"' (1) ·
Highly β1-selective adrenergic antagonist. Greater selectivity than metoprolol or atenolol. (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) ·
The d-enantiomer is a highly β1-selective antagonist; the l-enantiomer triggers endothelial nitric-oxide–mediated vasodilation. Unique among beta blockers for this NO mechanism. (1)

Pregnancy categories were retired by FDA in 2015. Quetiapine has reassuring active-comparator cohort data without consistent teratogenic signal; among the preferred neuroleptics when treatment is clinically necessary in pregnancy. See pregnancy_details for the full citation set. (1)
