Memantine HCl Chemical Properties,Usage,Production

Description

Memantine HCl is the HCl form of Memantine. Memantine is a well- known neuroprotective drug used for the treatment of Alzheimer’s disease. It is believed to be the first neuroprotective drug that has achieve clinical approval by US FDA as well as European. The development of Alzheimer’s disease involves the misfolded mutant proteins such as β-amyloid peptide (Aβ, particularly Aβ1−42). These misfolded mutant protein can increase the NMDA response and further cause severe excitotoxicity. Memantine suppresses this process through acting as the antagonist of the N-methyl-d- aspartate-sensitive glutamate receptor (NMDARs). Memantine is also under investigation as a potential treatment for other kind of neurodegenerative disorders such as HIV-associated dementia, neuropathic pain, glaucoma, depression, Huntington’s disease, ALS and movement disorders, among other.

Description

Memantine, a NMDA receptor antagonist, was co-developed by Forest Laboratories with Merz Pharmaceuticals and marketed under the trade name Namenda for the treatment of Alzheimer’s disease in the US after its approval in October, 2003. This drug has been available in many European and Asian markets before getting approval in the US.

Description

Memantine is an NMDA receptor antagonist that blocks NMDA-induced currents in rat retinal ganglion cells by 90% when used at a concentration of 12 μM. It reverses inhibition of dephosphorylation of the synthetic tau phosphopeptide p17 (tau_194-207) induced by the endogenous inhibitor of protein phosphatase 2A (PP2A) I₁^PP2A in vitro. In vivo, memantine (2 mg/kg) restores PP2A activity, decreases GSK-3β and amyloid-β (Aβ) levels in the hippocampus, cerebral cortex, and ventricular areas, and attenuates spatial learning and memory in the AAV1-I₁^PP2A rat model of Alzheimer''s disease. Memantine (20 mg/kg) reduces responding on the ethanol-associated lever in a cue-induced ethanol-seeking test in rats. It also decreases secretion of matrix metalloproteinase-9 (MMP-9), degradation of collagen IV, the size of cerebral ischemia-induced brain infarcts, and neuronal cell death in a mouse model of focal cerebral ischemia.

Chemical Properties

Crystalline Solid

Uses

Used as an antiparkinsonian and antispasmodic

Uses

Antiparkinsonian;Dopaminergic agonist

Uses

Anti Alzheimer's

Application

Memantine HCl has been used:

as a media supplement to serve as a control to study the neuroprotective effects of erythropoietin in N-methyl-D-aspartate receptor-induced toxicity.
to intraperitoneally inject experimental animal to study its effect on traumatic injury.
as a test compound to determine the dynamic range and selectivity of retinal pigment epithelium tissue penetration.

Definition

ChEBI: A hydrochloride obtained by reaction of memantine with one equivalent of hydrochloric acid. A low to moderate affinity uncompetitive (open-channel); NMDA receptor antagonist which binds preferentially to the NMDA receptor-operated cation channels.

brand name

Namenda(Forest).

General Description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Memantine Hydrochloride is a drug used for treating the Alzheimer′s disease by means of reducing abnormal activity in the brain. It can help patients suffering from dementia as it assists them to think more clearly and perform their chores with ease.

Biochem/physiol Actions

Memantine is effective against Alzheimer′s disease and Parkinson′s disease. It is also useful in treating epilepsy, motor neurone disease and trauma.

Side effects

Serious side effects:
Allergic reaction. Symptoms can include: swelling of your tongue, lips, or face; shortness of breath; skin rash; hives
Hepatitis (inflammation of the liver). Symptoms can include: yellowing of your skin or the whites of your eyes.
Pancreatitis (inflammation of the pancreas). Symptoms can include: severe nausea; severe abdominal pain.
Change in mental health. Symptoms can include: hallucinations; thoughts of suicide.
Congestive heart failure. Symptoms can include: shortness of breath; swelling in your feet and ankles.

Synthesis

Memantine (XV) or 1-amino- 3,5-dimethyladamantane hydrochloride was first synthesized by Lilly as an anti-diabetic agent but was ineffective in lowering blood sugar. Several syntheses have been detailed in the literature. However the simplest synthesis of the drug was done in one step from the commercially available 3,5-dimethyl adamantine (122). Treatment of 122 with nitrogen trichloride (CAUTION: very explosive gas!) in the presence of aluminum trichloride (ratio of 1.5:1.2) gave the desired amino adamantine in 86% yield. However, a much safer alternative has been reported by Lilly scientists. Heating the commercially available 3,5-dimethyladamantane 122 in bromine gave the bromo derivative 123 (86%) which was then reacted with sulfuric acid in acetonitrile to provide quantitatively acetyl amino derivative 124 after aqueous workup. Hydrolysis of the acetyl group was done by heating 124 with sodium hydroxide in diethylene glycol to give 1-amino -3,5- adamantane (96%), which was then made into the hydrochloride salt in ether and recrystallized from ether and alcohol mixture to provide the final product memantine hydrochoride XV.

Drug interactions

Drugs used to treat glaucoma:
Taking these drugs with memantine can increase the amount of memantine in your body. This can lead to more side effects. Examples of these drugs include: acetazolamide and methazolamide.
Sodium bicarbonate:
Taking memantine with sodium bicarbonate, which can be used to treat heartburn, can increase the amount of memantine in your body. This can lead to more side effects.
Parkinson’s disease medication:
Amantadine works in a similar way to memantine. Taking them together may lead to increased side effects.
Anesthesia medication:
Ketamine works in a similar way to memantine. Taking them together may lead to increased side effects.
Cough medication:
Dextromethorphan works in a similar way to memantine. Taking them together may lead to increased side effects.
