Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/11249721

Traxoprodil (CP-101,606) is a potent, selective N-Methyl-D-aspartate (NMDA) receptor (NR2B subunit) antagonist under development by Pfizer for its potential as a neuroprotectant in head injury and neurodegenerative disease. It is in phase II trials in the US and in phase I in Japan for the potential treatment of head injury, such as, Depressive Disorder, Major and Parkinson's Disease. CP-101,606 does not protect against glutamate-induced neurotoxicity in cultured cerebellar neurons, up to a dose of 10 uM. These results are consistent with CP-101,606 being a potent NMDA antagonist, selective for the type of NMDA receptor associated with the hippocampus. Some further investigation revealed that CP-101,606 was associated with a dose-related dissociation and amnesia. These results support the hypothesis that glutamate antagonists may be useful antidyskinetic agents. However, future studies will have to determine if the benefits of dyskinesia suppression can be achieved without adverse cognitive effects.

Sample Use Guides

CP 101,606 (TRAXOPRODIL) was administered at 0.25 mg/kg/hr for 2 hours followed by 0.12 mg/kg/hr for 2 hours, targeting a minimum plasma concentration of 60 ng/ml. “High dose” CP 101,606 was administered at 0.75 mg/kg/hr for 2 hours and then at 0.36 mg/kg/hr for 2 hours, targeting a minimum plasma concentration of 200 ng/ml. Matching placebo infusions were administered the control day. The study drug (CP-101,606 or placebo) were infused at a same infusion rates for each subject via a dedicated intravenous line.
