1. What is DEMAX and what is it used for?
• DEMAX 20 mg film tablets are available in blister packs of 28 and 84 tablets. It is a pink, oval biconvex film-coated tablet.
• Memantine belongs to the anti-dementia drug group and is an NMDA receptor antagonist. Memory loss in Alzheimer’s disease is due to impaired message signals in the brain. There are N-methyl-D-aspartate (NMDA) receptors in the brain, which are responsible for transmitting nerve signals that are important in learning and memory. Memantine improves the transmission of nerve signals and memory by affecting NMDA receptors.
• DEMAX is used in the following conditions. It is used in the treatment of moderate and severe Alzheimer’s disease.
