WASHINGTON AP – The U.S. Supreme Court said Tuesday investors who lost huge amounts betting on the blockbuster drug Vioxx can sue Merck & Co. over whether the pharmaceutical giant provided enough information about the painkiller’s risks before it was pulled from the market.

The high court agreed with a federal appeals court’s decision to allow a class-action securities lawsuit. The suit was over whether the drugmaker provided adequate information about the drug’s risks before its withdrawal.
