A nationwide class-action lawsuit was filed on behalf of all individuals who paid for prescriptions of the heart medication Cardizem CD, manufactured by Aventis, and/or its generic versions between 1998 and 2003. The lawsuit alleged Aventis and Andrx, maker of the generic version of Cardizem CD, conspired to keep the generic version off the market, causing consumers and third party payers to overpay for the drug. Aventis and Andrx agreed to pay $80 million, in addition to a separate $110 million settlement reached between the companies and drug wholesalers involving the same allegations.
