Namzaric is a prescription medication used to treat dementia in people with Alzheimer's disease. It is a combination medication comprised of memantine hydrochloride extended-release, a NMDA receptor antagonist, and donepezil hydrochloride, an acetylcholinesterase inhibitor.

Namzaric improves mental function by decreasing abnormal activity in the brain and by increasing the amount of a certain naturally occurring substance in the brain.

Namzaric comes as a capsule to be taken by mouth, once daily. The capsules can be opened to allow the contents to be sprinkled on food for patients who have difficulty swallowing.

Common side effects include headache, diarrhea and dizziness.
