Trimethadione is an oxazolidinedione anticonvulsant. It is used to treat epileptic conditions that are resistant to other treatments; recent studies by Doctor Jianxin Bao, Ph.D., at Washington University in Saint Louis's Central Institute For The Deaf's Center For Presbyacusis and Aging suggest that trimethadione, along with other oxazolidinedione anticonvulsant medications may be useful in treating sensorineural hearing loss cases like those of Iraq war veterans- if the drug's side effects, like dizziness, can be lessened by modifying the drug so it does not cross into the brain itself.
