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

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

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