Drugs for attention-deficit disorder including Novartis AG's Ritalin should carry the strictest possible warning of potential links to sudden death and heart risks, a U.S. advisory committee voted. The cautions should be highlighted with a black box on prescribing information, the Food and Drug Administration advisers decided today by an 8-7 vote, with 1 abstention. The FDA, which had sought advice on designing a study of the risks, hadn't asked for a warning recommendation. Cleveland Clinic heart specialist Steven Nissen made the motion during discussion. |
