Amantadine and memantine are NMDA receptor antagonists with neuroprotective properties
Johannes Kornhuber, Michael Weller, K. Schoppmeyer, P. Riederer. PubMed, 1994-01-01
Topic: Drug trials: efficacy and safety
The pharmacological inhibition of excitatory amino acid neurotransmission has evolved to be a major topic in neuropharmacology since enhanced synaptic action of glutamate and possibly other related neurotransmitters has been suggested to play a role both in acute neurological conditions such as ischemia and epilepsy and in chronic degenerative neurological diseases including Parkinson's disease, Huntington's disease and Alzheimer's disease. While antagonists at N-methyl-D-aspartate (NMDA) type glutamate receptors include psychotomimetic and neurotoxic agents such as phencyclidine and MK-801, the aminoadamantanes represent a class of drugs which may be largely free of such actions and which have already been used clinically as antiviral and antiparkinsonian agents. Multiple in vitro studies have recently delineated the neuroprotective properties of amantadine, and of its more potent congener, memantine, which appear to mediate neuroprotection via inhibition of NMDA receptor-dependent glutamate activity. Thus, neuroprotection targeting glutamate receptors does apparently not have to be associated with prominent psychotogenicity, and the development and evaluation of new neuroprotective drugs will have to performed in consideration both of the relative safety and of the good clinical effect of the already known and established aminoadamantanes.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
