Actavis plc has introduced Namzaric, a once-daily, fixed-dose combination of memantine hydrochloride extended-release (a NMDA receptor antagonist), and donepezil hydrochloride (an acetylcholinesterase inhibitor) across the United States. Namzaric was approved by the US Food and Drug Administration (FDA) in December for the treatment of moderate to severe Alzheimer's disease in patients stabilized on memantine hydrochloride and donepezil hydrochloride.
