What Is Donepezil-Memantine?
Donepezil improves the function of nerve cells in the brain. It works by preventing the breakdown of a chemical called acetylcholine (ah SEET il KOE leen). People with dementia usually have lower levels of this chemical, which is important for the processes of memory, thinking, and reasoning.
Memantine reduces the actions of chemicals in the brain that may contribute to the symptoms of Alzheimer's disease.
Donepezil and memantine is a combination medicine used to treat moderate to severe dementia of the Alzheimer's type.
Donepezil and memantine is not a cure for Alzheimer's disease. This condition will progress over time, even in people who take donepezil.
