High Quality Content by WIKIPEDIA articles! Topiramate (brand name Topamax) is an anticonvulsant (antiepilepsy) drug. It was originally produced by Ortho-McNeil Neurologics and Noramco, Inc., both divisions of the Johnson Johnson Corporation. This medication was discovered in 1979 by Bruce E. Maryanoff and Joseph F. Gardocki during their research work at McNeil Pharmaceutical. Generic versions are available in Canada and these were approved by the Food and Drug Administration (FDA) in September 2006. Mylan Pharmaceuticals was recently granted final approval for generic topiramate 25, 100, and 200 mg tablets and sprinkle capsules by the FDA for sale in the United States. 50 mg tablets were granted tentative approval. The last patent for topiramate in the U.S. was for pediatric use; this patent expired on February 28, 2009. On May 21, 2010, Ortho-McNeil pled guilty and was fined $6.14 million by the FDA for promoting Topamax to treat psychiatric disorders, without applying for any Federal government approval. Also, there was no data from any well-controlled clinical trial to demonstrate that Topamax was safe and/or effective to treat any psychiatric conditions at all.
