Aptiganel (Cerestat; CNS-1102) is a drug which acts as a noncompetitive NMDA antagonist.[1] It has neuroprotective effects and was researched for potential use in the treatment of stroke,[2] but despite positive results in animal studies,[3] human trials showed limited efficacy,[4] as well as undesirable side effects such as sedation and hallucinations,[5][6] and clinical development was ultimately not continued.[7]
