What is Namzaric?
Namzaric contains a combination of donepezil and memantine. Donepezil improves the function of nerve cells in the brain. It works by preventing the breakdown of a chemical called acetylcholine 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.
Namzaric is not a cure for Alzheimer's disease. This condition will progress over time, even in people who take donepezil.p>
