According to a theory known as the excitotoxicity theory, lower energy levels in the nerve cells of people with HD cause them to be overly sensitive to glutamate. Administer once daily in the evening. The terminal elimination half-life was significantly increased in patients with moderate to severe renal impairment, in comparison with patients with normal renal function Label. Mol Pharm. The unusual therapeutic utility of memantine probably results from inhibitory mechanisms shared with ketamine, combined with actions specific to memantine. At lower concentrations, which are normally used in the clinical setting, memantine can enhance neuronal synaptic plasticity in the brain, improve memory, and act as a neuroprotectant against the destruction of neurons caused by excitatory neurotransmitters 2. 2008 Feb;62(2):149-53.

The remainder of the drug is metabolized to three main metabolites. Mechanism of Action: use-dependent blockade of the ion channel pore of extrasynaptic NMDA receptors in the CNS (Johnson et al, 2015) 1) excessive NMDA stimulation caused by release of intracellular glutamate can occur during ischemia within the CNS; NMDA receptor over-stimulation results in excitotoxicity and further cellular damage. In this review we summarized clinical trial evidence of antidepressant effectiveness of memantine and its mechanisms of action. Approximately 48% of administered memantine is excreted unchanged in urine Label. The absorption is unaffected by food.
