Remacemide, also known as PR-934423 and FPL 12924AA, is a low-affinity NMDA antagonist with sodium channel blocking properties. It has been studied for the treatment of acute ischemic stroke, epilepsy, Huntington's disease, and Parkinson's disease. Remacemide binds weakly and noncompetitively to the ionic channel site of the NMDA receptor complex. Remacemide binds both allosterically and in the channel. However, because remacemide binds so weakly to NMDAR, much of remacemide's in vivo effect against excitotoxicity is thought to be caused by its metabolic transformation to the more potent desglycine derivative FPL 12495.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
