Feedback:
The drug, memantine hydrochloride (Namenda) has a low-to-moderate affinity for N-methyl-D-aspartate (NMDA) receptors with no effects on dopamine, GABA, histamine, glycine, or adrenergic receptor sites. It is believed that persistent activation of the central nervous system NMDA receptors contributes to the symptoms of Alzheimer's disease. By blocking these sites, it is thought that the symptoms are reduced or delayed. Other options are incorrect.
