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
