Irampanel
Chemical compound
Irampanel (INN, code name BIIR-561) is a drug which acts as a dual noncompetitive antagonist of the AMPA receptor and neuronal voltage-gated sodium channel blocker.[1][2] It was under development by Boehringer Ingelheim for the treatment of acute stroke/cerebral ischemia but never completed clinical trials for this indication.[3][4] Irampanel was also trialed, originally, for the treatment of epilepsy and pain, but these indications, too, were abandoned,[1] and the drug was ultimately never marketed.
