1. What is Polmatine and what is it used for
What is Polmatine
Polmatine belongs to a group of medicines called 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 the transmission of nerve signals that are important for learning and memory. Polmatine belongs to a group of medicines known as NMDA receptor antagonists. Polmatine, by acting on NMDA receptors, improves the transmission of nerve signals and memory.
What is Polmatine used for
Polmatine is used for the treatment of patients with moderate to severe Alzheimer's disease.
