Donepezil
Donepezil is a cholinesterase inhibitor used for cognitive symptoms in Alzheimer’s disease. It increases the amount of acetylcholine available in the brain. Aricept contains donepezil alone; Donamem includes donepezil with memantine.
Key points
- Donepezil is a cholinesterase inhibitor.
- Aricept represents 5 mg and 10 mg single-ingredient tablets.
- Donamem adds memantine to donepezil.
- Donepezil can support symptoms but does not stop the underlying disease.
Aricept follows the single-ingredient pathway
Aricept connects with Alzheimer’s disease and dementia in the neurology category. Its two recorded strengths contain donepezil without another active ingredient.
By slowing acetylcholine breakdown, donepezil may support memory, attention, communication and daily activities for a time. Official information is careful to describe symptom control rather than cure.
Donamem adds memantine
Donamem is recorded as a donepezil and memantine tablet. Memantine acts on NMDA receptors, so the combination brings together two distinct neurological mechanisms.
Donepezil can slow heart rate and cause fainting. Nausea, diarrhoea and weight loss are common concerns, while gastrointestinal bleeding and seizures require particular attention. These ingredient-specific effects remain relevant whether donepezil appears alone or with memantine.
