Zonampanel

Zonampanel (INN, code name YM872) is a quinoxalinedione derivative drug and competitive antagonist of the AMPA receptor which was being investigated by Yamanouchi/Astellas Pharma as a neuroprotective drug for the treatment of ischemic stroke but never completed clinical trials.[1][2][3][4] In clinical trials, zonampanel produced severe side effects including hallucinations, agitation, and catatonia in patients, resulting in early termination of the trials.[5]
