How Memantina Flas Stadafarma works

Memantina Flas Stadafarma contains the active ingredient hydrochloride of memantine.

Memantine belongs to a group of medications known as antidementia 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. Memantine belongs to the group of medications called NMDA receptor antagonists. Memantine acts on these receptors by improving the transmission of nervous signals and memory.
