Study Details

Brief summary:

Ketamine is a medication that came into clinical practice in the 1960's. Ketamine is used as an anesthetic and to provide pain relief. Recently, Ketamine was approved to treat drug resistant depression using subanesthetic doses. In the hospital setting, intravenous anesthetic dosages are used to treat unrelenting seizures known as status epilepticus in comatose patients. Ketamine in subanesthetic doses has not been tried as a treatment for medication resistant seizures in the outpatient setting. This study would like to examine the effectiveness of subanesthetic ketamine in outpatients who suffer from drug resistant epilepsy.
