Selfotel (CGS-19755) is a drug which acts as a competitive NMDA antagonist, directly competing with glutamate for binding to the receptor.[1] Initial studies showed it to have anticonvulsant, anxiolytic, analgesic and neuroprotective effects,[2][3] and it was originally researched for the treatment of stroke,[4] but subsequent animal and human studies showed phencyclidine-like effects,[5][6][7][8] as well as limited efficacy and evidence for possible neurotoxicity under some conditions,[9][10][11] and so clinical development was ultimately discontinued.[12][13]
