A new combo pill has been approved by the FDA to treat Alzheimer's disease in people being treated by both drugs.

The pill, called Nanzaric, is taken once a day and can be sprinkled on food for patients who have trouble swallowing. It is meant to treat moderate to severe Alzheimer's disease and combines memantine hydrochloride extended-release (Namenda) and donepezil hydrochloride (Aricept), which are often prescribed in tandem.

David Nicholson (PhD), senior vice president of global brands R&D for drugmaker Actavis, said, "Both Namenda XR and donepezil have proven efficacy and safety for the treatment of moderate to severe Alzheimer's disease."
