1. What is Memantina Stadafarma and what is it used for
How Memantina Stadafarma works
Memantine belongs to a group of medications known as anti-dementia medications.
Memory loss in Alzheimer's disease is due to an alteration in brain signals. The brain contains so-called N-methyl-D-aspartate (NMDA) receptors that participate in the transmission of important nerve signals in learning and memory. Memantine belongs to the group of medications called NMDA receptor antagonists. Memantine acts on these receptors, improving the transmission of nerve signals and memory.
What Memantina Stadafarma is used for
Memantine is used in the treatment of patients with moderate to severe Alzheimer's disease.
2. What you need to know before taking Memantina Stadafarma
