Ebixa – Memantine Hydrochloride uses, dose and side effects


5 mg, 10 mg, 15 mg and 20 mg Film-coated tablets 
Memantine hydrochloride

1. What Ebixa is and what it is used for

Ebixa contains the active substance memantine hydrochloride and belongs to a group of medicines known as anti-dementia medicines. Memory loss in Alzheimer’s disease is due to a disturbance of message signals in the brain. The brain contains so-called NMDA receptors (N-methyl-D-aspartate) that are involved in the transmission of nerve signals that are important for learning and memory. Ebixa belongs to a group of medicines called NMDA receptor antagonists. Ebixa acts on these NMDA receptors by improving the transmission of nerve signals and memory.

Ebixa is used to treat patients with moderate to severe Alzheimer’s disease.
