Mechanism of action of memantine Mechanism of action of memantine Johnson, Jon W; Kotermanski, Shawn E 2006-02-01 00:00:00 Memantine is a clinically useful drug in many neurological disorders, including Alzheimer’s disease.
MECHANISM OF ACTION . Persistent activation of central nervous system N-methyl-D-aspartate (NMDA) receptors by the excitatory amino acid glutamate has been hypothesized to contribute to the symptomatology of Alzheimer’s disease. Memantine is a low affinity NMDA receptor antagonist which binds preferentially to the NMDA receptor-operated cation channels. There is no evidence that memantine
Study objective was to study the mechanisms of analgesic action of PK-66 compound in rats using the pharmacological analysis. We evaluated the mechanisms of analgesic effect of PK-66 (1 mg/kg, intraperitoneal) compound on the thermal irritation model on Hours 1, 2, 4 and 6 after administration of study compounds.
Memantine is an uncompetitive N -methyl-d-aspartate receptor antagonist and probably also has an indirect dopaminergic action at high concentrations. We describe a person with Alzheimer’s disease who developed chorea and dystonia after inadvertently doubling of her daily dose by taking extended-release (XR) memantine twice daily, rather than
Memantine is postulated to exert its therapeutic effect through its action as a low to moderate affinity uncompetitive (open channel) NMDA receptor antagonist, which binds preferentially to the NMDA receptor-operated cation channels. It blocks the effects of pathologically elevated sustained levels of glutamate that may lead to neuronal dysfunction. There is no clinical evidence that memantine
The difference in memantine’s mechanism of action and pharmacodynamics may account for memantine’s apparent lack of effectiveness as an algesic. While memantine should not be used as first-line analgesia, further research is required before definitive conclusions can be drawn.
possible dopamine agonistic mechanism of action for memantine. Chorea mostly occurs with lesions in the striatum or with D2 receptor over-activity, causing in hypofunction of the indirect pathway. Conversely, dystonia has a strong association with hyperfunc-tion of the direct pathway (D1 overactiv- ity). In both chorea and dystonia, there is inappropriate disinhibition of thalamic projections

Lewy body dementia (LBD) is a progressive brain disease manifest as dementia and parkinsonism, along with psychotic and autonomic disorders. Although studies in recent years have demonstrated the positive effects of cholinesterase inhibitors in LBD, the search for therapeutic agents with other mechanisms of action remains relevant.
Memantine’s suggested neuroprotective effect 2,8 may also increase brain levels of the neuronal marker, N-acetyl aspartate (NAA). Because NAA is found primarily on neuronal axons in the brain, 9 perhaps the neuroprotective effect of memantine can be measured by quantifying the change in NAA concentrations in brain tissue via magnetic resonance spectroscopy.
Memantine is eliminated in a mono-exponen- cause interindividual variability and may assist cli- tial manner with a terminal elimination half-life (t 1 / nicians in the individualisation of memantine dos-

Memantine is a clinically useful drug in many neurological disorders, including Alzheimer’s disease.

Memantine’s suggested neuroprotective effect 2,8 may also increase brain levels of the neuronal marker, N-acetyl aspartate (NAA). Because NAA is found primarily on neuronal axons in the brain, 9 perhaps the neuroprotective effect of memantine can be measured by quantifying the change in NAA concentrations in brain tissue via magnetic resonance spectroscopy.
