Pridopidine
Pridopidine (Huntexil, formerly ACR16) is an experimental drug candidate belonging to a class of agents known as dopidines, which act as dopaminergic stabilizers in the central nervous system. These compounds may counteract the effects of excessive or insufficient dopaminergic transmission, and are therefore under investigation for application in neurological and psychiatric disorders characterized by altered dopaminergic transmission, such as Huntington's disease (HD).
