mechanism:
None (1) ·
Competitive antagonist at OX1R and OX2R. First-in-class DORA. Receptor dissociation slower than lemborexant or daridorexant. (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) ·
Synthetic T4 (thyroxine); peripherally deiodinated to T3 (triiodothyronine), the active hormone. '"`UNIQ--vote-00000031-QINU`"' Narrow therapeutic index; brand-to-generic switches can shift TSH and require re-titration'"`UNIQ--ref-00000032-QINU`"'. (1) ·
'"`UNIQ--vote-00000032-QINU`"' Brand-to-brand and lot-to-lot variability in T3:T4 ratio is greater than with synthetic levothyroxine, which is why endocrine guidelines prefer the synthetic'"`UNIQ--ref-00000033-QINU`"'. (1) ·
'"`UNIQ--vote-0000111B-QINU`"' Intraoperative floppy iris syndrome is a recognized class effect. Recently emerging evidence (observational) suggests possible Parkinson's disease risk reduction via PGK1 binding — investigational and not a clinical indication'"`UNIQ--ref-0000111C-QINU`"'. (1)
uses:
Insomnia (sleep onset and/or maintenance) in adults (FDA-approved August 2014). Also studied for insomnia in mild-moderate Alzheimer disease. (1) ·
Major depressive disorder in adults (FDA-approved 2013). Notable for evidence of cognitive benefit (processing speed) that distinguishes it from other antidepressants. (1) ·

starting dose:
1 mg PO at bedtime to limit first-dose syncope; titrate weekly to 5-10 mg (1) ·
1.6 mcg/kg/d in young healthy adults; 25-50 mcg/d in elderly or cardiac disease, titrated by TSH at 6-8 weeks (1) ·
10 mg PO 30 min before bedtime (with ≥7 hours of sleep planned) (1) ·
