Glutamate-based therapeutic approaches: clinical trials with NMDA antagonists
Muir KW.. Current opinion in pharmacology, 2005-12-15
Topic: Brain proteins, microglia and lab models
The majority of clinical trials of N-methyl d-aspartate antagonists have been conducted in the fields of stroke, traumatic brain injury (TBI) and dementia. Stroke and TBI trials have involved more than 9000 patients, but have yielded no therapeutically useful agents, with the possible exception of magnesium for treatment of subarachnoid haemorrhage. Several of the synthetic N-methyl D-aspartate antagonist development programmes have been abandoned owing to concerns about drug toxicity, particularly in stroke. Systematic reviews in stroke and TBI have shown that definitive conclusions cannot be drawn for most agents owing to early termination of trials. In dementia, memantine has shown some benefit in moderate-to-severe Alzheimer's disease, with no clear benefit to date for milder stages of Alzheimer's disease or for vascular dementia. Other therapeutic areas of promise remain inadequately explored at present.

How this study scored 47/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported 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 27 of the 58 points we could judge it on, which is 47 out of 100.
