RIVAMER 1.5 mg is a medication primarily used in the treatment of Alzheimer's disease. It contains Rivastigmine as the active ingredient, which is a cholinesterase inhibitor. Rivastigmine works by increasing the levels of acetylcholine in the brain, a neurotransmitter that plays an essential role in memory and learning. By inhibiting the enzyme acetylcholinesterase, which breaks down acetylcholine, RIVAMER helps to improve symptoms or slow down the progression of cognitive decline associated with Alzheimer's and other neurodegenerative diseases. It is available in various forms, such as tablets and patches, and is typically prescribed to patients in the early to moderate stages of Alzheimer's disease.
