What is Memantina Normon

Memantina Normon belongs to a group of medications known as dementia medications.

The loss of memory in Alzheimer's disease is due to an alteration in brain signals. The brain contains called N-methyl-D-aspartate (NMDA) receptors that participate in the transmission of important nervous signals in learning and memory. Memantina Normon belongs to the group of medications called NMDA receptor antagonists. Memantina Normon acts on these receptors by improving the transmission of nervous signals and memory.
