Used primarily in the treatment of mild to moderate dementia associated with Alzheimer's disease. It functions by increasing the levels of acetylcholine in the brain, a neurotransmitter involved in memory and cognition. This helps improve mental function, including memory, awareness, and ability to perform daily activities. Often prescribed as a long-term management option to slow the progression of symptoms, though it does not cure the underlying disease. Commonly taken orally in tablet or disintegrating tablet form, with effects typically seen over several weeks of regular use.
