Galantamine is a medication primarily used to treat mild to moderate Alzheimer's disease. It works by increasing levels of a neurotransmitter called acetylcholine, which is important for memory and learning. By enhancing communication between nerve cells, galantamine can help improve cognitive function and slow the progression of symptoms in some patients. This drug is typically taken in pill form and may also be available as a liquid. Common side effects include nausea, vomiting, and diarrhea. It is important for patients to discuss their medical history with a healthcare provider before starting treatment with galantamine.
