What are indications for the use of AXURA?
AXURA is to be used for treating patients with moderately severe to severe Alzheimer's disease.
Memory loss associated with Alzheimer's is caused by a disruption in the transmission of brain signals. So-called NMDA receptors in the brain assist in transmission of nerve signals essential to learning and memory functions. AXURA belongs to a group of medications called NMDA receptor antagonists. AXURA stimulates these NMDA receptors and improves transmission of nerve signals and thereby the memory.
