Alzheimer's Disease Flashcards
What are the three currently available cholinesterase inhibitor Alz drugs.
Galantamine
Donepezil
Rivastigmine
Why do cholinesterase inhibitors help AD?
They help compensate for the loss of acetylcholine that results from the degeneration of cholinergic nerve terminals in AD
Specific details on Galantamine
Selective, Reversible inhibitor of acetylcholinesterase
Enhancer of action of ACh on nicotinic receptors
Specific details on Donepezil
Specific, Reversible inhibitor of AChase
Specific details on Rivastigmine
Inhibitor of AChase AND butyrylcholinesterase
Alz treatment that utilizes anti-glutamatergic therapy
Memantine
(Mg also has an effect, btu Mem stays longer, has a better decrease in Ca influx.
Memantine specific details
NMDA antagonist that blocks glutamatergic neurotransimission via noncompetitive mechanism.
Excess glutamate leads to excitotoxicity, neuronal death
New beta amyloid imaging technique for AD
Florbetapir
