What is memantine used for?
Cholinesterase inhibitors also work to increase communication between cells but target a different neurotransmitter.
What neurotransmitter helps with memory?
Signals communicated across brain cells essentially enable us to think, learn, and remember. A neurotransmitter called glutamate helps this process by carrying the signals across cells, but patients with Alzheimer’s have too much glutamate , and the excess throws the process awry, damaging the cells, even killing them, and muddling the message. Memantine prevents excess glutamate from killing cells, without damaging the signal.

What is the target of NMDA?
Targeting the glutamatergic system, specifically NMDA receptors, offers a novel approach to treatment in view of the limited efficacy of existing drugs targeting the cholinergic system. Memantine is a low-affinity voltage-dependent uncompetitive antagonist at glutamatergic NMDA receptors.
Which receptor does memantine interact with?
Memantine acts as an agonist at the dopamine D 2 receptor with equal or slightly higher affinity than to the NMDA receptors.
When was Memantine approved?
Memantine was approved for medical use in the United States in 2003. It is available as a generic medication. In 2017, it was the 149th most commonly prescribed medication in the United States, with more than four million prescriptions.
Does memantine inhibit glutamatergic receptors?
Memantine is a low-affinity voltage-dependent uncompetitive antagonist at glutamatergic NMDA receptors. By binding to the NMDA receptor with a higher affinity than Mg 2+ ions, memantine is able to inhibit the prolonged influx of Ca 2+ ions, particularly from extrasynaptic receptors, which forms the basis of neuronal excitotoxicity. The low affinity, uncompetitive nature, and rapid off-rate kinetics of memantine at the level of the NMDA receptor-channel, however, preserves the function of the receptor at synapses, as it can still be activated by physiological release of glutamate following depolarization of the postsynaptic neuron. The interaction of memantine with NMDA receptors plays a major role in the symptomatic improvement that the drug produces in Alzheimer's disease. However, there is no evidence as yet that the ability of memantine to protect against NMDA receptor-mediated excitotoxicity has a disease-modifying effect in Alzheimer's, although this has been suggested in animal models.
Does memantine affect cognitive function?
It can be noted that memantine is an antagonist at Alpha-7 nAChR, which may contribute to initial worsening of cognitive function during early memantine treatment. Alpha-7 nAChR upregulates quickly in response to antagonism, which could explain the cognitive-enhancing effects of chronic memantine treatment.
