Exelon Patch (Rivastigmine)

Rivastigmine belongs to a family of medications known as cholinesterase inhibitors. It is used to treat symptoms of mild to moderate Alzheimer's disease. Alzheimer's disease is caused by the constant degeneration of certain nerve cells in the brain that make a chemical called acetylcholine. This chemical is thought to be important for the processes of learning and memory. Rivastigmine prevents the breakdown of acetylcholine, thereby increasing its levels in the brain. Rivastigmine may improve cognitive function (memory, orientation, and language) and general ability to perform activities of daily living. Rivastigmine patch may take several weeks to begin working, and individual response varies.
