1. What is Memantin NeuroPharma and what is it used for

How Memantin NeuroPharma works

Memantin NeuroPharma contains the active substance memantine hydrochloride. It belongs to the group of anti-dementia medicines.
Memory loss in Alzheimer's disease is caused by disturbances in the transmission of nerve impulses that carry information in the brain. In the brain, there are so-called N-methyl-D-aspartate (NMDA) receptors that are involved in the transmission of nerve signals important for the learning process and for memory processes. Memantin NeuroPharma belongs to a group of medicines called NMDA receptor antagonists. Memantin NeuroPharma, by affecting NMDA receptors, improves the transmission of nerve impulses and memory.

What Memantin NeuroPharma is used for

Memantin NeuroPharma is used to treat patients with moderate to severe Alzheimer's disease.
