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-00000016-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-00000017-QINU`"'. (1) ·
'"`UNIQ--vote-0000104D-QINU`"' Adequate hydration is at least as important as the drug in producing the expectorant effect clinically. Used in combination with dextromethorphan, decongestants, or antihistamines in many proprietary OTC cold preparations. (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) ·
