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 50 mg and above safely improved tinnitus scores over 16 weeks.[12]
