A cholinesterase inhibitor that increases the levels of acetylcholine, a neurotransmitter important for memory and cognitive function.
An nmda receptor antagonist that modulates the activity of glutamate, another neurotransmitter involved in learning and memory. it helps protect against excessive glutamate activity, which can be damaging to brain cells.
Treatment of moderate to severe Alzheimer's disease
Donepezil inhibits the breakdown of acetylcholine, improving cholinergic neurotransmission. Memantine modulates the effects of glutamate, reducing neuronal damage caused by excessive glutamate activity. The combination therapy aims to address both cholinergic deficiency and glutamatergic excitotoxicity, common features in Alzheimer's disease.
