WASHINGTON (AP) -- Only 15 percent of new drugs approved in the last decade were novel chemicals that the Food and Drug Administration deemed a significant improvement over older drugs, a study says. 

The vast majority instead were similar to existing medicines. Yet during the same time, consumer spending on prescription drugs more than doubled to $132 billion -- and most of the increase was spent not on the most innovative drugs, but on the less important or copycats, says the study by the National Institute for Health Care Management.
