====== Donepezil ====== //Donepezil// is a prescription-only drug used to alleviate some of the symptoms of [[content:medicine:diseases:a-f:alzheimers|Alzheimer's]] disease. There are currently around 5 million prescriptions per year in the US alone. It's sold under the brand names of //Aricept//, //Namzaric// and others. The drug is a centrally-acting inhibitor of enzymes which reduce the levels of naturally occurring acetylcholine, thus increasing its availability - but the 'mechanism of action' with regard to Alzheimer's is currently unknown.
