1. What is Memantina Kern Pharma and what is it used for
How Memantina Kern Pharma Works
Memantina Kern Pharma belongs to a group of medications called 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 Kern Pharma is Used For
Memantina Kern Pharma is used in the treatment of patients with moderate to severe Alzheimer's disease.
