Rivastigmine is a medication used to treat mild to moderate dementia caused by Alzheimer’s disease or Parkinson’s disease. It belongs to a class of drugs called cholinesterase inhibitors. Rivastigmine works by increasing the levels of certain neurotransmitters in the brain, such as acetylcholine, which are important for memory and cognitive function. By boosting these neurotransmitter levels, rivastigmine helps to improve cognitive function and slow down the progression of dementia symptoms. Rivastigmine is typically taken orally in the form of capsules or a solution, and it may also be available in a patch form for transdermal administration
