mechanism:
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-00000138-QINU`"' Decreases urinary calcium (used in stone prevention); raises serum uric acid, glucose, and lipids modestly; non-anion-gap hypokalemic metabolic alkalosis is the characteristic electrolyte pattern'"`UNIQ--ref-00000139-QINU`"'. (1) ·
'"`UNIQ--vote-00000255-QINU`"' Less potent and shorter-acting than PPIs but with faster on-effect; suitable for on-demand acid suppression. Largely renally cleared; dose-adjust in renal impairment to avoid CNS effects (confusion in elderly)'"`UNIQ--ref-00000256-QINU`"'. (1) ·
'"`UNIQ--vote-00000E4A-QINU`"' The narrow safe-bolus window for IV use (sharp risk of arrhythmia, hypertensive emergency, intracerebral hemorrhage) is why anaphylaxis dosing is '''IM, not IV''', outside critical care'"`UNIQ--ref-00000E4B-QINU`"'. (1)
