Memantine HCl – Solution, 600mg (20mg/mL)

Memantine HCl – Solution, 600mg (20mg/mL)

This premium laboratory-grade research compound is supplied as a ready-to-use aqueous solution (20mg/mL in water), engineered for modern scientific investigations requiring precise NMDA receptor pharmacology and neuroprotection research. Memantine (1-amino-3,5-dimethyladamantane hydrochloride) is an adamantane derivative that acts as an uncompetitive, low-affinity, voltage-dependent, rapidly unbinding antagonist of NMDA glutamate receptors, functioning as an open-channel blocker that selectively enters the receptor-associated ion channel during its open state and blocks extrasynaptic NMDA receptors, preventing disruption of normal synaptic transmission and safeguarding against excitotoxicity-induced neuronal cell death, FDA-approved for moderate to severe dementia in Alzheimer’s disease and commonly used in combination with acetylcholinesterase inhibitors, demonstrating neuroprotective properties valuable for in vitro/in vivo modeling of Alzheimer’s disease, Parkinsonism, epilepsy, motor neurone disease, traumatic brain injury, and cognitive impairment research.

All domestic orders ship directly from primary United States production facilities, ensuring rapid delivery to all 50 U.S. states.

Research Applications & Storage Protocols

NMDA Receptor Antagonist with Neuroprotective Profile

Memantine HCl functions as an uncompetitive, low-affinity, voltage-dependent, rapidly unbinding antagonist of NMDA (N-methyl-D-aspartate) glutamate receptors that acts as an open-channel blocker selectively entering the receptor-associated ion channel during its open state and blocking extrasynaptic NMDA receptors (NMDAR), preventing disruption of normal synaptic transmission and safeguarding against excitotoxicity-induced neuronal cell death. Memantine is an adamantane derivative effective against Alzheimer’s disease and Parkinson’s disease, also useful in treating epilepsy, motor neurone disease and trauma, FDA-approved for moderate to severe dementia in Alzheimer’s disease and commonly used in combination with acetylcholinesterase inhibitors for Alzheimer dementia treatment. The antagonist activity of memantine (2-33 µM) on NMDA receptors of cultured superior collicular and hippocampal neurons has been studied extensively, with protective effect against NMDA receptor-mediated glutamate toxicity in cultured cerebellar, cortical and mesencephalic neurons investigated, demonstrating memantine (100 µM) diminishes spontaneous synaptic activity with action potential frequencies above 6 Hz in cultured mouse nerve cells, and memantine (2 µM) reduces neuronal damage caused by HIV-1 coat protein gp120 in cultured rat ganglion retinal cells. Memantine exerts action through uncompetitive NMDA receptor antagonism, binding preferentially to NMDA receptor-operated cation channels, and also has antagonistic activity at type 3 serotonergic (5-HT3) receptor with potency similar to NMDA receptor, and lower antagonistic activity at nicotinic acetylcholine receptor, stimulating dopamine release, making it valuable for investigators studying Alzheimer’s disease mechanisms, Parkinsonism, neuroprotection, excitotoxicity prevention, cognitive impairment, traumatic brain injury, epilepsy, motor neurone disease, and NMDA receptor pharmacology in in vitro and in vivo experimental models.
