An individual formulation containing solely carbidopa was generated to treat nausea in patients where the combination therapy [levodopa]/carbidopa is not efficient reducing nausea.   The first approved product by the FDA containing only carbidopa was developed by Amerigens Pharmaceuticals Ltd and approved on 2014. On the other hand, the combination treatment of carbidopa/levodopa was originally developed by Watson Labs but the historical information by the FDA brings back to the approval of this combination therapy developed by Mayne Pharma in 1992."}]
