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-0000083E-QINU`"' CYP2C9 substrate; no clinically active metabolites. The IDNT trial established renoprotection in diabetic nephropathy independent of BP lowering, contributing to the ARB class indication in T2DM with proteinuria'"`UNIQ--ref-0000083F-QINU`"'. (1) · '"`UNIQ--vote-00000AEA-QINU`"' The 24-hour half-life supports once-daily dosing with consistent overnight BP control. Largely hepatically cleared (~98% biliary); no significant renal clearance dependence'"`UNIQ--ref-00000AEB-QINU`"'. (1)
