With an estimated $51 billion of branded drugs coming off patent between 2006 and 2011, both U.S. government insurance plans and private, third-party payers will promote increased use of generics in the future. In a data-rich report that employs analyses of 34 branded drugs facing generics competition between January 2002 and December 2006, we highlight the most effective strategies employed by pharmaceutical companies in their effort to ward off the threat of generics competition.
