1. what memantine mylan is and what it is used for

Memantine Mylan contains the active substance memantine. It 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 N-methyl-D-aspartate (NMDA)-receptors that are involved in transmitting nerve signals important in learning and memory. Memantine Mylan belongs to a group of medicines called NMDA-receptor antagonists. Memantine Mylan acts on these NMDA-receptors improving the transmission of nerve signals and the memory.

Memantine Mylan is used for the treatment of patients with moderate to severe Alzheimer’s di­sease.

2. what you need to know before you take memantine mylan
