What is Memantine HCl?

Memantine is the first in a novel class of Alzheimer’s disease medications acting on the glutamatergic system by blocking NMDA receptors. It was first synthesized by Eli Lilly and Company in 1968. Memantine is marketed under the brandAxura and Akatinol by Merz, Namenda by Forest, Ebixa and Abixa by Lundbeck and Memox by Unipharm. Memantine has been shown to have a modest effect in moderate-to-severe Alzheimer’s disease and in dementia with Lewy bodies. Despite years of research, there is little evidence of effect on mild Alzheimer’s disease.

Mechanism of action

Memantine is approved by the U.S. F.D.A and the European Medicines Agency for treatment of moderate-to-severe Alzheimer’s disease, and has now received a limited recommendation by the UK’s National Institute for Health and Care Excellence for patients who fail other treatment options. Within the new guidance memantine is recommended as an option for managing Alzheimer’s disease for people with: moderate Alzheimer’s disease who are intolerant of or have a contraindication to AChE (acetylcholinesterase) inhibitors or those with severe Alzheimer’s disease.

Memantine has been associated with a moderate decrease in clinical deterioration with only a small positive effect on cognition, mood, behavior, and the ability to perform daily activities in moderate to severe Alzheimer’s disease. There does not appear to be any benefit in mild disease.

Adverse Effects

Memantine is, in general, well-tolerated. Common adverse drug reactions (?1% of patients) include confusion, dizziness, drowsiness, headache, insomnia, agitation, and/or hallucinations. Less common adverse effects include vomiting, anxiety, hypertonia, cystitis, and increased libido. It has been reported to induce reversible neurological impairment in multiple sclerosis patients, which led to the halt of an ongoing clinical trial. Though exceedingly rare, extrapyramidal side effects (such as dystonic reactions, etc.) may occur, in particular, in the younger population.

Like many other NMDA antagonists, memantine behaves as a dissociative anesthetic at supratherapeutic doses, and has substituted for phencyclidine in rodent and primate drug discrimination studies. Despite isolated reports, recreational use of memantine is rare due to the drug’s long duration and limited availability.

A recent study demonstrates therapeutically-relevant doses of memantine in the mouse can lead to disruption of cognitive flexibility.
