Used in the treatment of mild to moderate dementia associated with Alzheimer's disease and Parkinson's disease. It works by increasing the levels of certain neurotransmitters in the brain involved in memory and cognition. The compound helps improve mental function, such as thinking, memory, and awareness, in patients by inhibiting the breakdown of acetylcholine and butyrylcholine. It is administered orally in capsule or solution form and is sometimes available in transdermal patch form for steady delivery, reducing gastrointestinal side effects.
