Alzheimer Treatment: Reminyl, Galantamine Hydrobromideextended release galantamine hydrobromide)The purpose of this medication Reminyl ER is one of a group of drugs called cholinesterase inhibitors which are used to treat symptoms in people with mild to moderate Alzheimer's disease. In the brains of people with Alzheimer's disease there is a progressive degeneration of nerve cells, particularly of the cells that make acetylcholine, a chemical thought to be important for learning and memory. Because of this, people with Alzheimer's disease have lower brain levels of acetylcholine. Reminyl ER works principally by reducing the breakdown of acetylcholine and thus increasing the amount of the chemical in the brain.
