Namenda is the first and only NMDA-receptor antagonist approved to treat moderate to severe Alzheimer's disease. Of the 5.1 million people that have Alzheimer's disease, the majority are in the moderate to severe stages. Namenda works in an entirely different way than currently available medications, and provides benefits when used alone, or in combination with an acetylcholinesterase inhibitor (AChEI).

The most common adverse events reported with NAMENDA vs placebo (≥ 5% and higher than placebo) were dizziness, confusion, headache, and constipation. In patients with severe renal impairment, the dosage should be reduced.
