Galanthamine is a reversible, competitive acetylcholinesterase (AChE) inhibitor and a naturally occurring isoquinoline alkaloid. It is primarily used as an active pharmaceutical ingredient (API) in medications for the treatment of mild to moderate Alzheimer's disease, where it increases acetylcholine levels in the brain to improve cognitive function, memory, and daily activities. It has also been investigated for potential applications in vascular dementia, traumatic brain injury, neuroprotection, schizophrenia, and nicotine addiction.
