Traxoprodil (CP-101,606) is a drug developed by Pfizer which acts as an NMDA antagonist, selective for the NR2B subunit.[1][2] It has neuroprotective,[3] analgesic,[4] and anti-Parkinsonian effects in animal studies.[5][6] Traxoprodil has been researched in humans as a potential treatment to lessen the damage to the brain after stroke,[7][8][9][10] but results from clinical trials showed only modest benefit.[11]The drug was found to cause EKG abnormalities (QT prolongation) and its clinical development was stopped.[12] More recent animal studies have suggested traxoprodil may exhibit rapid-acting antidepressant effects similar to those of ketamine,[13] although there is some evidence for similar psychoactive side effects and abuse potential at higher doses,[14] which might limit clinical acceptance of traxoprodil for this application.
