ORLANDO, Fla. -- About 11 million Americans take cholesterol-lowering drugs known as statins. They're the most widely-sold drugs in this country. Some doctors say they're over-prescribed while others say they're not prescribed enough.
Elaine Overton's cholesterol was 260, so her doctor put her on Lipitor. "My cholesterol dropped about 100 points in about six weeks' time," she said. "It was really remarkable."
Statins can lower cholesterol by 40 percent and prevent heart attacks. The newest research shows they also reduce the risk of a second stroke by 16 percent.
