Strattera is the brand name for atomoxetine, a selective norepinephrine reuptake inhibitor that was one of the first nonstimulant medications available for the treatment of ADHD. Since the drug's patent expired in May, four companies — Apotex Inc., Teva Pharmaceuticals USA Inc., Aurobindo Pharma Limited, and Glenmark Pharmaceuticals Limited — have unveiled generic versions of the drug. All four were approved on May 30; it's unclear when the generics will be made available to consumers.
