1. Package Contents and Additional Information

1. What is Memantina TecniGen and what is it used for

How Memantina TecniGen Works

Memantina TecniGen 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. Memantina TecniGen belongs to the group of medications called NMDA receptor antagonists. Memantina TecniGen acts on these receptors, 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.

2. Taking Memantina TecniGen

Do Not Take Memantina TecniGen

Warnings and Precautions

Consult your doctor or pharmacist before starting to take Memantina TecniGen:

In these situations, treatment should be carefully supervised, and your doctor should regularly reassess the clinical benefit of memantine.

If you have kidney problems, your doctor should closely monitor your kidney function and, if necessary, adjust the dose of memantine.

The use of memantine with other medications such as amantadine (for the treatment of Parkinson's disease), ketamine (a medication generally used as an anesthetic), dextromethorphan (a medication for the treatment of cough), and other NMDA antagonists should be avoided.
