Research has shown that armodafinil significantly improves driving simulator performance in patients with SWD. Armodafinil consists of the (\u2212)-R-enantiomer of the racemic modafinil. Armodafinil is produced by the pharmaceutical company Cephalon Inc. (a wholly owned subsidiary of Teva Pharmaceutical Industries Ltd.) and was approved by the U.S. Food and Drug Administration (FDA) in June 2007."}]
