| pregnancy | | intro = '''Suvorexant''' (brand name Belsomra) is the first FDA-approved dual orexin receptor antagonist (DORA), approved August 2014 for insomnia. Suvorexant established the DORA class as a treatment paradigm, reducing arousal via orexin blockade rather than enhancing GABA-mediated inhibition. Subsequent DORAs (lemborexant 2019, daridorexant 2022) have been positioned as iterative improvements with different pharmacokinetics. | ||

| intro | Suvorexant has been studied in mild-moderate Alzheimer disease with positive results; trials have suggested potential for reducing sleep-disordered breathing exacerbations and possibly delaying cognitive decline (though the cognitive claim remains controversial). | ||
| pharmacodynamics= Competitive antagonist at OX1R (Ki ~0.55 nM) and OX2R (Ki ~0.35 nM). Receptor dissociation slower than lemborexant or daridorexant. | |||
| effects = Next-day somnolence (more common than with daridorexant due to longer half-life), headache, abnormal dreams, dry mouth, fatigue. Sleep paralysis and hallucinations near sleep onset. Complex sleep behaviors class warning. | |||
