Donepezil + Memantine

Uses of Donepezil + Memantine

Donepezil + Memantine is used to manage symptoms of moderate to severe Alzheimer's disease. Donepezil helps improve the levels of a chemical involved in memory and thinking, while Memantine helps regulate another chemical involved in learning and memory.

This combination is commonly used for:

• Alzheimer's disease: Helps improve or stabilise memory, thinking, and daily functioning in people with moderate to severe disease.
• Cognitive decline: Helps manage the worsening of cognitive symptoms such as confusion and memory loss.
• Behavioural symptoms of dementia: May help improve certain behavioural symptoms associated with moderate to severe Alzheimer's disease.

Side effects of Donepezil + Memantine

  • Nausea

  • Vomiting

  • Diarrhoea

  • Headache

  • Fatigue

How Donepezil + Memantine works

Donepezil + Memantine works through two separate actions on brain chemicals involved in memory and learning.

Donepezil belongs to a class of medicines called cholinesterase inhibitors. It works by blocking an enzyme that breaks down acetylcholine, a chemical messenger involved in memory and learning. This increases the amount of acetylcholine available in the brain, helping improve communication between nerve cells.

Memantine belongs to a class of medicines called NMDA receptor antagonists. It works by regulating the activity of a chemical called glutamate. In Alzheimer's disease, excess glutamate activity can damage nerve cells. Memantine helps protect nerve cells from this damage while still allowing normal learning and memory processes to occur.

Together, Donepezil supports the chemical signals needed for memory, while Memantine protects nerve cells from further damage, providing broader support for cognitive function.
