mechanism:
None (2) ·
Donepezil: reversible AChE inhibitor, increases synaptic acetylcholine. Memantine: uncompetitive low-affinity NMDA receptor antagonist, dampens pathological glutamate overactivation while preserving normal synaptic signaling. Targets two distinct mechanisms in Alzheimer's. (1) ·
Highly β1-selective adrenergic antagonist. Greater selectivity than metoprolol or atenolol. (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) ·
'"`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-0000124C-QINU`"' The 400 mg/d dose for migraine prophylaxis is supported by randomized trials (Schoenen 1998) and remains a low-risk evidence-based supplement option. Characteristic bright-yellow urine fluorescence with high-dose oral supplementation. (1)
