Donep-M Tablet 15's, also known as a "neurological medicine," is largely used to treat Alzheimer's disease (memory loss). Alzheimer's disease is a neurodegenerative condition that progressively damages the brain. It results in brain shrinkage and the death of brain cells (neurons).A combination drug called Donep-M Tablet 15s contains both Memantine and Donepezil, two drugs used to treat Alzheimer's. A cholinesterase inhibitor called donepezil helps the brain's nerve cells function better by preventing the oxidation of the neurotransmitter acetylcholine. Memantine works by reducing the amount of the brain chemical that contributes to the symptoms of Alzheimer's disease. Together, they maintain equilibrium in the brain's levels of chemical messengers and aid in the transmission of nerve signals.Disclaimer:For more information contact your physician.
