In a development that is likely shaking the world of health insurance, Ohio Attorney General Dave Yost on Monday sued six corporate entities over the way they facilitate drug transactions. Yost filed the suit under the Valentine Act — Ohio’s antitrust law — accusing the companies of improperly colluding to fix prices and other actions regarding prescription drugs.
The main target of the lawsuit is St. Louis-based Express Scripts. It’s one of the three biggest drug middlemen in the United States.
