History
First made in 1966, it was patent-protected by Geigy in 1969 through DE 2011087 . It was approved for use as an anticonvulsant in Denmark in 1990, Spain in 1993, Portugal in 1997, and eventually for all other EU countries in 1999. It was approved in the US in 2000. In September 2010, Novartis, of which Geigy are part of its corporate roots, pleaded guilty to marketing Trileptal for the unapproved uses of neuropathic pain and bipolar disorder. Research
Research has investigated the use of oxcarbazepine as a mood stabilizer in bipolar disorder, with further evidence needed to fully assess its suitability. It may be beneficial in trigeminal neuralgia. References

Though proximity to open watersheds was linked to incidence in some areas, suggesting that outdoor activity within the city may be connected to many cases, there is also an increasing body of evidence that even the interiors of buildings may be risk areas. An early case concerned a prisoner who was confined to prison during the whole of his likely blastomycotic incubation period. An epidemiological survey found that although many patients who contracted blastomycosis had engaged in fishing, hunting, gardening, outdoor work and excavation, the most strongly linked association in patients was living or visiting near waterways. Based on a similar finding in a Louisiana study, it has been suggested that place of residence might be the most important single factor in blastomycosis epidemiology in north central Wisconsin. Follow-up epidemiological and case studies indicated that clusters of cases were often associated with particular domiciles, often spread out over a period of years, and that there were uncommon but regularly occurring cases in which pets kept mostly or entirely indoors, in particular cats, contracted blastomycosis. The occurrence of blastomycosis, then, is an issue strongly linked to housing and domestic circumstances. Seasonal trends
Seasonality and weather also appear to be linked to contraction of blastomycosis. Many studies have suggested an association between blastomycosis contraction and cool to moderately warm, moist periods of the spring and autumn or, in relatively warm winter areas. However, the entire summer or a known summer exposure date is included in the association in some studies. Occasional studies fail to detect a seasonal link.
