[24][25][26] The interaction of memantine with NMDA receptors plays a major role in the symptomatic improvement that the drug produces in Alzheimer's disease. [10][11] There does not appear to be any benefit in mild disease.[12]. This causes more damage to the nerve cells. Memantine is a clinically useful drug in many neurological disorders, including Alzheimer's disease. Agent for Alzheimer's Dementia Pharmacology (Mechanism of Action) ❖ Memantine is though to exert its therapeutic effect through its action as a low to moderate affinity uncompetitive (open-channel) NMDA receptor antagonist ❖ It bind preferentially to the NMDA receptor-operated cation channels to reduce their persistent activation Memantine is a medication used to treat moderate-to-severe Alzheimer's disease. We use cookies to help provide and enhance our service and tailor content and ads. Memantine is a primary aliphatic amine that is the 3,5-dimethyl derivative of 1-aminoadamantane.A low to moderate affinity uncompetitive (open-channel); NMDA receptor antagonist which binds preferentially to the NMDA receptor-operated cation channels. Too little or too much glutamate can lead to cell death. (For more on the excitotoxicity theor… [15][16] Recent scientific journal reports are showing guarded promise with severe obsessive compulsive disorder. Memantine mechanism of action. [34], In the US, some CNS activities were discovered at Children's Hospital of Boston in 1990, and Children's licensed patents covering uses of memantine outside the field of ophthalmology to Neurobiological Technologies (NTI) in 1995. the different state of mind you experience with memantine treatment and the new ways of thinking it creates can make you stumble a little the first time. 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.[25]. [3] It is believed to work by blocking NMDA receptors. Megan Brooks. Dosage Forms and Strengths. [42][43] In August 2015, Actavis' request was denied. [20], A dysfunction of glutamatergic neurotransmission, manifested as neuronal excitotoxicity, is hypothesized to be involved in the etiology of Alzheimer's disease. Memantine reduces the actions of chemicals in the brain that may contribute to the symptoms of Alzheimer's disease. 2015 Feb;20:54-63. doi: 10.1016/j.coph.2014.11.006.
