Galanthamine is primarily used in the treatment of mild to moderate Alzheimer's disease. It works by inhibiting acetylcholinesterase, an enzyme that breaks down acetylcholine, thereby increasing the levels of this neurotransmitter in the brain. This helps to improve cognitive function, memory, and daily living activities in patients with Alzheimer's. Additionally, galanthamine has been explored for its potential use in other cognitive disorders, such as vascular dementia and traumatic brain injury. It is also being studied for its neuroprotective properties and potential benefits in conditions like schizophrenia and nicotine addiction. The compound is typically administered orally in the form of tablets or capsules, and its dosage is carefully adjusted based on the patient's response and tolerance.
