Investigation and a pending class action lawsuit against Schering-Plough, Upsher-Smith and American Home Products on behalf of a class of direct purchasers of the brand-name drug K-Dur 20.
K-Dur 20 is a potassium chloride supplement used to treat patients with depleted potassium. The class action lawsuit alleges that Schering-Plough, Upsher-Smith, and American Home Products violated federal antitrust law by entering into written, anticompetitive agreements under which Schering-Plough paid its rival generic manufacturers, Upsher-Smith and American Home Products, $90 million to delay the market entry of their generic versions of K-Dur 20. The class claims that, as a result of these anti-competitive agreements, purchasers of K-Dur 20 were forced to pay artificially high prices for the drug entity sold as K-Dur 20. One defendant, American Home Products, has agreed to settle with a class of direct purchasers of K-Dur 20 for $2.1 million and other consideration. Litigation against the remaining defendants is ongoing.
