How Memantina TecniGen works

Memantina TecniGen belongs to a group of medications known as dementia medications.

The loss of memory in Alzheimer's disease is due to an alteration in brain signals. The brain contains receptors called N-methyl-D-aspartate (NMDA) that participate in the transmission of important nerve signals in learning and memory. Memantina TecniGen belongs to the group of medications called NMDA receptor antagonists. Memantina TecniGen acts on these receptors by improving the transmission of nerve signals and memory.

What Memantina TecniGen is used for

Memantina TecniGen is used in the treatment of patients with moderate to severe Alzheimer's disease.

Do not take Memantina TecniGen

If you are allergic to hydrochloride memantine or to any of the other components of this medication (listed in section 6).
