Memantine Benefits
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.
Medical Use
Memantine is used to treat moderate-to-severe Alzheimer's disease, especially for people who are intolerant of or have a contraindication to AChE (acetylcholinesterase) inhibitors.One guideline recommends memantine or an AChE inhibitor be considered in people in the early-to-mid stage of dementia.
Memantine has been associated with a modest improvement; with small positive effects on cognition, mood, behavior, and the ability to perform daily activities in moderate-to-severe Alzheimer's disease. There does not appear to be any benefit in mild disease.
Memantine when added to donepezil in those with moderate-to-severe dementia resulted in "limited improvements" in a 2017 review. The UK National Institute of Clinical Excellence (NICE) issued guidance in 2018 recommending consideration of the combination of memantine with donepezil in those with moderate-to-severe dementia. Effects in autism are unclear. Recent scientific journal reports are showing guarded promise with severe obsessive compulsive disorder.
