Sabeluzole (R-58,735) is a nootropic and neuroprotective drug which was originally developed for the treatment of Alzheimer's disease,[1][2] and has subsequently been researched for other applications such as sleep apnoea.[3] It acts primarily as an NMDA antagonist,[4] but other mechanisms of action may also be important.[5][6]
