Can Alzheimer's drugs prevent progression of mild cognitive impairment to Alzheimer's disease?

Clinical trials testing whether Alzheimer's drugs might prevent progression of MCI to Alzheimer's have generally shown no lasting benefit. One way Alzheimer's disease harms the brain is by decreasing levels of a chemical messenger (acetylcholine) that's important for alertness, memory, thought and judgment.

What are cholinesterase inhibitors for Alzheimer's disease?

The medications are Razadyne® (galantamine), Exelon® (rivastigmine), and Aricept® (donepezil).

Is Aricept a cholinergic drug?

It belongs to a class of drugs called cholinesterase inhibitors that also includes tacrine (Cognex). Scientists believe that Alzheimer's disease may result from a deficiency in chemicals (neurotransmitters) used by nerves in the brain to communicate with one another.

What are examples of cholinergic drugs?

Examples of direct-acting cholinergic agents include choline esters (acetylcholine, methacholine, carbachol, bethanechol) and alkaloids (muscarine, pilocarpine, cevimeline). Indirect-acting cholinergic agents increase the availability of acetylcholine at the cholinergic receptors.

What is anticholinergic medication used for?
