mechanism:
None (2) ·
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) ·
'"`UNIQ--vote-00000015-QINU`"' Pediatric ingestion (capsule chewed or punctured) releases the free local anesthetic and causes seizures, cardiac arrhythmia, and death'"`UNIQ--ref-00000016-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) ·
'"`UNIQ--vote-00001302-QINU`"' Renally cleared; accumulation in advanced CKD can produce neuromuscular and cardiac depression. Hypomagnesemia frequently co-exists with hypokalemia and is often the reason refractory potassium loss does not correct until magnesium is repleted. (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) ·
