Final answer:
Donepezil is a cholinergic agent used in the treatment of mild to moderate dementia of the Alzheimer's type. It enhances cholinergic functions by increasing the concentration of acetylcholine, which slows the progression of Alzheimer's disease.
Step-by-step explanation:
Donepezil is a cholinergic agent used in the treatment of mild to moderate dementia of the Alzheimer's type. It enhances cholinergic functions by increasing the concentration of acetylcholine. By blocking the enzyme that degrades acetylcholine, Donepezil allows for more of the neurotransmitter to bind to receptors on postsynaptic cells, enhancing communication between neurons in the brain. This increase in neuronal communication can help restore some lost functions in early Alzheimer's disease and slow its progression.
