Neramexane is a drug related to memantine ,[1] which acts as an NMDA antagonist [2] and has neuroprotective effects.[3] It is being developed for various possible applications, including treatment of tinnitus ,[4] [5] Alzheimer's disease ,[6] drug addiction [7] and as an analgesic .[8] Animal studies have also suggested antidepressant [9] and nootropic [10] actions, so there are a wide range of potential applications this drug may be used for. It also acts as a nicotinic acetylcholine receptor antagonist .[11]
A clinical trial found that doses of 50mg and above safely improved tinnitus scores over 16 weeks.[12]
