TRENTON, N.J. (AP) — Growing use of generic medicines has reduced U.S. health care spending by more than $1 trillion over the past decade, according to an industry-funded study released Thursday.

The fourth annual report, produced for the Generic Pharmaceutical Association, found use of generic prescription drugs in the U.S. saved about $193 billion last year alone. That amount was up 22 percent from the $158 billion in savings from generics in 2010, and was more than three times the $60 billion in savings in 2002, the report states.
