What is Razadyne?
Razadyne improves the function of nerve cells in the brain. It works by preventing the breakdown of a chemical called acetylcholine (ah see til KO leen). People with dementia usually have lower levels of this chemical, which is important for the processes of memory, thinking, and reasoning.
Razadyne is used to treat mild to moderate Alzheimer's type dementia.
