What Marbodin is and what it is used for

How Marbodin works

Marbodin 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. Marbodin belongs to a group of medicines called NMDA receptor antagonists. Marbodin acts on these NMDA receptors by improving the transmission of nerve signals and memory.

What Marbodin is used for

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

Memantine hydrochloride contained in Marbodin may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professionals if you have any further questions, and always follow their instructions.
