1. What is Memantine Qualigen and what is it used for
How Memantine Qualigen works
Memantine Qualigen belongs to a group of medicines called anti-dementia medicines.
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 are involved in the transmission of important nerve signals in learning and memory. Memantine Qualigen belongs to the group of medicines called NMDA receptor antagonists. Memantine Qualigen acts on these receptors, improving the transmission of nerve signals and memory.
What Memantine Qualigen is used for
Memantine Qualigen is used in the treatment of patients with moderate to severe Alzheimer's disease.
