None (5) · 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-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)
