How Memantina Pensa works

Memantina Pensa belongs to a group of medications known as dementia medications. Memory loss 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 Pensa belongs to the group of medications called NMDA receptor antagonists. Memantina Pensa acts on these receptors by improving the transmission of nervous signals and memory.
