Detailed explanation-1: -Donepezil, rivastigmine and galantamine all prevent an enzyme called acetylcholinesterase from breaking down acetylcholine. This means there is a higher concentration of acetylcholine in the brain, which leads to better communication between nerve cells. This may ease some symptoms of Alzheimer’s disease for a while.
Detailed explanation-2: -Galantamine, rivastigmine, and donepezil are cholinesterase inhibitors that are prescribed for mild to moderate Alzheimer’s symptoms. These drugs may help reduce or control some cognitive and behavioral symptoms.
Detailed explanation-3: -Donepezil (Aricept) is approved to treat all stages of the disease. It’s taken once a day as a pill. Galantamine (Razadyne) is approved to treat mild to moderate Alzheimer’s.
Detailed explanation-4: -Cholinesterase inhibitors increase the overall amount of acetylcholine available.
Detailed explanation-5: -Acetylcholine (ACh), a neurotransmitter essential for processing memory and learning, is decreased in both concentration and function in patients with Alzheimer’s disease.
