Topiramate (brand name Topamax) is an anticonvulsant drug produced by Ortho-McNeil Neurologics, a division of Johnson & Johnson. It is used to treat epilepsy in both children and adults. In children it is also indicated for treatment of Lennox-Gastaut syndrome (a disorder that causes seizures and developmental delays). It is also Food and Drug Administration (FDA) approved for, and now most frequently prescribed for, the prevention of migraines. It has been used by psychiatrists to treat bipolar disorder, although it is not FDA approved for this purpose and such use is somewhat controversial. This drug has been investigated for use in treatment of obesity, especially to aid in the reduction of binge eating, and also as a possible treatment for alcoholism. However, these uses are not actively promoted by the manufacturer, and like its use for bipolar disorder, are off-label uses. The drug is also used in clinical trials to treat Post Traumatic Stress Disorder. A pilot study suggests that Topiramate is possibly effective against infantile spasm. In May 2006 the U.S. National Institutes of Health web site clinicaltrials.gov listed several studies sponsored by Ortho-McNeil which propose to examine the use of topiramate on migraine, cluster, and severe headaches within various demographics. Other off-label and investigational uses of Topiramate include: treatment of bulimia nervosa, smoking cessation, treatment of neuropathic pain.
